- In this video I look at the most common cause of Volvo Penta Fuel Pump whine that I see. I show you what we do in our shop to resolve the issue and show you our process of changing the fuel filter. We have a close look at the fuel tank pickup, as well as the anti-siphon valve, and how to inspect them.

Hi, You really explained that well. I have confidence that when I do the things you talked about that my problem will be resolved. And if it is not, it will certainly be of value to the engine. Thanks Mate!
Excellent presentation!
We are appreciate you sharing your knowledge with all of us.
New subscriber because you have the best Volvo maintenance videos I’ve found so far!!! Keep them coming !!!
Thank you Kevin, those are very kind words. Been busy the last couple months but plan on more videos coming out soon. Thanks for subscribing.
Great video sir! I'm looking at buying a boat with a VP 8.1 Gi and EVERYONE is telling me to watch out for dreaded fuel pump issues. Coming from Merc the fuel sytems on VP seem more accesible and easy to understand. Your video help take the mystery out of VP!
To anyone having fuel starving, backfiring issues on Volvo Penta engines: had the same issue on my '04 Four Winns 250 Horizon with VP 8.1L Gi. I had bought the boat used, but could only run on its trailer before buying. Ran fine on muffs!
Went through the fuel system from tank to fuel pumps, everything checks out: fuel clean, good pressures. Took it to local Four Winns dealer who started at the other end of the fuel system, drained the fuel rails. Bam! Water in the fuel going into the injectors! Where's that coming from? The water cooling jacket on the fuel cell was leaking water directly into the fuel before being picked up by the high pressure fuel pump. Put a couple pieces of hose on the water nipples on the fuel cell, one with a plug and one with a Schrader valve. Hooked up an air pump with gauge, fuel cell water jacket wouldn't hold pressure.
Worked with Man Cave Mechanic in MI to swap out my fuel cell core, checked that new one would hold pressure in the water jacket. Yep. Had accumulated some rust in the high-pressure fuel system - here comes a good word for Evapo-Rust. Let it sit in my fuel rail upside down overnight, no acid in Evapo-Rust to attack any seals. Rinsed it out. Had my fuel injectors ultrasonically cleaned and put in new screens. Boat's been running like a beast past 4 years!
So to anyone suspecting a fuel system issue, start at the other end first....check the pressure and quality of the fuel going into the cylinders first, then work BACKWARD to the tank! Also, nothing like an in-water, full throttle test before buying.
That is good advice. These Volvos are getting to the age that corrosion in the fuel cooler is becoming an issue. I expect to be changing more of them in the future for this exact reason.
Can you help more, I have the same problem and sometimes the fuel pump sucking fuel is stop working but when I unplug the high pressure wire then it start working?
@@aaalammari Sorry. But that is nothing like my problem. I had a water leak in the fuel cooling jacket but the pumps were working fine. Sounds like you have an electrical problem or something inside the pumps themselves.
Well done! Clear and concise. I was hearing some intermittent "whining" and thought the pump was just going bad. Great preliminary things to check as I troubleshoot my fuel pump problem. Thank you!
Did you fix your whining problem?
Yes. It took a bit of time and a little frustration. No restrictions mentioned here in the fuel line. I checked and broke off my anti syphon valve in the syphon tube fitting so both of those needed replacing. My issue was black paint flakes in both the pump and pressure regulator screens. With the help of videos from "Man Cave Mechanic", I ended up removing the black paint from the interior of my fuel pump assembly. After that I tested in the shop and all was good. I went to the lake and the engine ran terribly after a few minutes of cruising and barely made it back to the ramp. The problem was found to be that I did not quite tighten the anti syphon valve in the syphon tube fitting enough and I was sucking a small amount of air. Once that was remedied, it ran great. I also replaced the pressure regulator in the troubleshooting process but I don't think that really had anything to do with the fix. I'm glad I got all the black paint removed and my original pumps are now functioning great. @@erich9063
Thank you! Thank you! Thank you from Alabama!
These are great videos and very helpful. One suggestion, you could create playlists for each motor brands that you discuss. Having recently moved from a single yamaha outboard to twin volvo penta i/o I am trying to learn as much as possible and your videos are the best I found online. All the best from Vancouver Island
Thanks for the suggestion, I am beginning to get some playlists together now that I am getting a larger catalog of videos. I certainly need to make it easier for people to find the information they are looking for.
Thanks for the kind words, and tanks for watching.
Excellent video. You have been a wealth of information, thank you!
Great video and very timely for me.
Awesome, thanks for watching.
Excellent and informative video! Thank you!
You're very welcome! And thank you for watching.
Awesome video . Tks for sharing the video . It has helped solve out pump issue
That's great, glad I could help.
I have just recently run across your great vids and subscribed. Thank you for the efforts!
For the dreaded VP fuel pump whine, I understood another potential cause was the internal paint that VP uses on these pumps. It eventually flakes off due to the ethanol and clogs the passages. I too had this whine and a check of the incoming line was done as you outlined but no restrictions. I replaced the fuel pick up and check valve nipple for good measure anyway, but whine persisted. Note: the replacement Moeller fuel pickups no longer have the screen on the bottom of the tube. And my milage was down. Continuing to poke at it I found that I had excessive high side pressure (100 vs 50 PSI) so out comes the regulator and I find it clogged with what appeared to be paint form the pump. Turns out VP issues a Service Bulletin P-23-7 Number 3 Version 01 that removes the regulator’s screen. So, a combination of new regulator minus the screen, plus a new VP pump - with the internal paint removed - and the whine gone. And milage back up. Been running for a few years now like this with my 5.0 GXi-E and no issues! Note: I did pull apart my original pump and wow! what a mess inside due to the paint pealing off!
You are totally correct, and thanks for sharing that for everyone. I did this video because I have seen too many people replace their pump assembly and still have a noisy pump because they didn't clean the pickup side. In our shop we have seen more blocked suction side than the paint problem, although I think I have just had one come in and I may do a video on it.
Thanks for watching and subscribing.
Since you took the pump apart to have a look at it, in your estimation would it be advisable for me to do the same to clean it out to continue using it? i plan on replacing the fuel filter, cleaning the pickup, and removing that screen on the regulator as per the bulletin.
I found my filter area has been leaking and there may also be a slight whine i noticed on the water yesterday. I've been noticing a strong fuel smell after shutting off the engine and opening the panels.
Thank you!
Thanks!
You showed the pickup tube orientated on its side parallel to the bottom of the tank, is that correct?
I have a 1987 Volvo Penta, 5.7 G. I've had it for 20 years and I've been through 5 fuel pumps. I've checked the pickups. I checked the filters in the tank out of the tank. For some reason, the fuel pumps just burn out is that normal.
Thanks for the great video! Do you use teflon tape on the threads when re-installing the anti-siphon valve and the fuel tank fitting?
I use a Mercury marine product called "Perfect Seal" on the threads, it is similar to an aviation gasket sealer, but thicker. You do need to seal the threads somehow or you will get an air leak into the fuel system. Teflon tape will work, or any other thread sealer that is compatible with fuel.
@@CanadaWideMarine Perfect. Thanks!
Very helpful video. I see you replaced the filter with a longer one, 18-8149. I normally use 18-7989. They are both 10 micron filters. Do you recommend that replacement because of increased capacity?
If it will fit I always prefer to install a larger capacity water separator. If you have very good control over the fuel going into your boat the larger capacity may not be needed. By very good control I mean inspecting your fuel before it goes into your tank, I highly recommend using a funnel with a water separating filter, it saves a lot of heartache.
perfect timeing i just installed new volvo penta , and it has a very loud fuel pump and eventualy dies ,runs out of fuel, will check my ant siphon valve 1st before ordering a new pump
Happy to be of help. Thanks for watching.
Very helpful, but what if I do everything in yrou video and it still is shining? Do I replace the whole pump or just the high pressure side? I have 2006 8.1 OSI-C Engine
That is a question worth asking. In our shop we would replace the whole assembly because the rest of it is also 16 years old. If the low pressure pump failed a couple months after replacing the high pressure, the customer could be upset that they are broken again and are paying for a repair that could have been done the first time. Taking into account lost boating time, towing back and forth to the shop and the extra labour is a pretty big factor. If you are happy to wait for the low pressure side to fail to maybe save a few dollars or spread out the expense you can just replace the one side.
Does a 2013 380 VP suffer from restrictions or paint issues? If there was a restriction causing a low-speed fuel pump whine, wouldn’t you expect a corresponding lack of performance due to fuel starvation at WOT?
It could suffer from either problem, and many other possibilities as well. A compete and proper diagnostic will define exactly what the problem is. A restriction to the fuel pump can cause a lack of performance, particularly at higher rpm and load. Many boaters never see those conditions, every situation is unique. It is impossible to to cover every single possible cause of a certain problem in a youtube video.
If youve got a moment. I need a part number for the pickup and elbow. Mine sheared off in the tank. Gonna try and recover with an easy out...what a silly thing to happen. 7.3GSI PEFS Motor.
The pickup and elbow are specific to your fuel tank. We will need thread size and depth of tank. You can email: support@canadawidemarine.com, or call us toll free: 1 855 949 8176
Would the belt tensioner pulley on that engine in the video be a normal right hand thread as it rotates clockwise to loosen the belt?
Yes it is.
Thanks for the video. I'm tracking down a fuel pump whine and issue. Do you replace the fuel pickup tube, check valve, and strainer? Or is there a way to clean them effectively?
Hello Carl. Generally I have found that the anti siphon valve, pickup tube and strainer can be cleaned by simply blowing out with compressed air. If there is a varnish or sludge buildup in the anti siphon valve I will replace that so it works properly.
One other thing you can check is the pressure regulator on the fuel rail. I recorded some video on this but seem to have misplaced it. There is a simple clip you can pull out to access the regulator. There is a fine filter screen on the regulator that can become blocked causing the fuel pressure too high. This can also cause a whine in the pump. I will re-do a video on this next time I see it.
Thanks for watching.
@@CanadaWideMarine Thank you! I will give those a clean. I took them out but didn't see any sludge. My pickup didn't have a strainer, just an open tube. I will take off the whole fuel line and check as well. I've cleaned the FPR mesh a few times, I even removed all the injectors, cleaned those, so the fuel rail, FPR, and injectors are good. The pump is new this year and is one of the non-interior painted ones from ManCaveMechanic. So I'm narrowing down my issue to something in the fuel pickup, or the fuel filter itself which I'll swap out too.
Have you checked your low and high fuel pressures?
@@CanadaWideMarine No but going to check tonight!
I saw that in your video and other comments so I want to do that as well as cleaning all the bits on the supply side too. Again, thanks for everything.
Thanks for the helpful tip on the VP 5.7 Gxi. Have you encountered an issue where the engine starts fine at cold start and you run it for a few minutes shut it down and it will not restart unless you put the throttle in neutral and give it gas then it will run fine all day until you shut it down again. I've been having to leave the engine on all day to avoid this, but with gas prices so high it's draining my wallet. Any info or tips would be greatly appreciated. Thx
Hello Cesar, thanks for watching our videos. There are many possible causes for the problem you are describing, the best advice I can give you is to invest in having a marine mechanic diagnose your problem before you start spending money on replacing parts you may not need to replace. It should only take one or two hours to diagnose your problem accurately. See my video: th-cam.com/video/pAjbGZhagZA/w-d-xo.html for more information.
I have same issue on 5.0gxi, let us know if you figure it out!
I had the same issue with VP 5.0Gi. It was the Water temperature sensor not well plugged. Disconnect, clean them & reconnect it.
When priming the fuel filter, I've seen many videos showing opposite of how you're doing so. They hold they're thumb over the center hole and fill in around the outter holes..... How important is one method over the other? I'm assumng it's about the draw.....
Great question. In operation the fuel enters the filter through the outside ring of holes, passes through the filter media, then exits through the center hole. So if you want to be absolutely certain that all your fuel is being filtered yes, pour it into the outside ring of holes and not in the center. I find it easier to just use clean fuel, from a clean container to fill the filter. I'm not sure why anyone would want to use dirty fuel to prime a new fuel filter.
Do you drain the tank prior to checking the anti-siphon valve?
Hi, Chris.
No need to drain the fuel tank to check the anti-siphon valve, if it is on the top of the fuel tank.
Thanks for watching our videos.
I put a 8.1l in a m1123 humvee, is there any reason i cant/shouldn't use the same external pump you have here?
No reason at all really, but you will pay a premium for it being a marine pump with raw water cooling. You won't be using the cooling with your engine coolant, (too hot). So it does not seem like the right choice, unless you just happen to have one kicking around.
There are plenty of aftermarket pumps and pump systems available. If you need some help choosing something feel free to contact me at info@jimobalek.com with more details of your build and I can help you out.

Very helpful, but would like part numbers included.
part numbers are different for different models, so rather than have someone assume what part number they need it's best to give us a call or email with your make model and serial number and we will happily look up the exact part number you need. Toll Free: 1 855 949 8176

Got an '07 8.1 ... mine ( and MANY others have that range ) takes 3862228 ( if they haven't changed it this week )
I have a 2005 Volvo Penta 5.0 with fuel pump issues. It has no anti siphon at the tank. Should I add one? I'm replacing the fuel pump this week
Yes, you should definitely add an anti-siphon valve for safety. you don't want a small leak in a fuel line to drain your fuel tank into your bilge.
@@CanadaWideMarine is this something I can pick up at a parts store or do you recommend a good source to order from?
Any marine store should have them. We do not have them listed on Canadawidemarine.com but if you use the chat function, or email us at support@canadawidemarine.com we can set you up and ship them to you.
I just replaced my fuel filter and now my pump whines and the engine backfires at higher rpm. Any idea?
You may have dislodged some debris and caused a blockage, restricting fuel flow. Or you may have an air lock in the pump. I always pre fill my filters with "clean" fuel before installing them. Electric pumps do not like to suck, but are very good at pushing fuel.
@@CanadaWideMarine I filled it with some fuel from a gas can before installing it. You think I should try putting another fuel filter on it? Engine runs perfectly fine until I go over 5000 rpm. I have the new Penta 240.
I would definitely try a new filter if that is all you changed and now have a running issue.
Would this also cause the boat to have loss of power and backfire under acceleration?
A restriction in the fuel supply will certainly cause those symptoms.
I am having the same the same issue. I run dual fuel tanks and I switched tanks to isolate the fuel feed. No change. The fuel filter is new and pump is whining off and on ,which it did not do before . Thoughts on what else the issue is.? It is a 2015 5.7 with 240 hours . Thank you
I would look closely at the common fuel supply line feeding the pump first, then I would investigate the pump itself. There were issues with the black paint contaminating the pump internally causing the whine. I have never seen it happen myself, but have heard that it was a problem with them.
@@barrywalton3894 I just went through my entire fuel system. Pickup line was clogged, anti siphon valve was gummed up. Cleaned those and still same issue. I then started going through the entire system. Spin on filter had paint flakes in it, the screen on the bottom of the HP pump had flakes in it, and the screen on the fuel pressure regulator. Cleaned all of them, still same issue. Ran pressure test on the low and hi pressure pump. Both were below where they should be. Long story short, that way I know everything is new and good to go, I am replacing my entire fuel system. Pickup tube, anti siphon valve, filter, fuel pumps, fuel lines, and regulator. We will see how it goes.
@@ryankimble4743 thanks for the info .I have a new fuel pump ordered. Had to go with a after market one. Volvo one is not available. Hopefully this is the issue. The boat acted up once last fall with backfiring and loss of power shut the engine down and restarted and never had an issue again until last weekend and put it in the water and it started backfiring about 5 minutes after being on plane .
my fuel pump does not look like this one pictured..
if we have eliminated all possible restrictions and still have a pump thats whining after you accelerate for about 30 seconds and then continues to run terribly and whine. pull it out take home, check things replace things, go back and same thing..
this is a brand new pump
I assume you have not done a fuel pressure test. Check low pressure and high pressure side. If I remember correctly low pressure should be 8 psi, high pressure 50. This will ensure both pumps are actually working. It is possible for say the low pressure pump to not be getting power, (or ground), and still have the high pressure pump working and doing all the work. Another possibility you may find is a blocked return screen in the fuel pressure regulator, this will present as pressure over 50 psi on the high pressure side.
The problem with youtube diagnostics is it is not possible to cover all the possibilities.
#unintentionalasmr 🥰🤩😇
This is all wrong … the pump gets noisy because the water lines get plugged up coming from the thermostat. And the pump runs hot. Or the vapor separator gets blocked up with salt and causes the fuel to turn into vapor. Has nothing to do with the inlet lines. Or the filter. Also. Volvo recommends not to fill the filter before install because the center is unfiltered. Then u can bring contaminates into the fuel pressure regulator screen and block it up which is a service bulletin to remove the screen and put a e clip on it. ..because it will cause the fuel pressure to spike to 100psi. When the paint fails
Inside the fuel pump tank and feeds black paint chips into the injectors and for screen. I’m a Volvo penta rapid response dealer.
So you are saying that all those fuel pump whines I have repaired over the years somehow had the water cooling lines cleared out when I cleaned the blocked suction side of the fuel supply? How did that happen? In fact, the last one I repaired because of paint blocking the regulator, (yes, I am familiar with the tech bulletin) had great water flow through the cooling lines because I happened to be checking that out also.
How about you try admitting it is not "all wrong" and accepting that there can be multiple causes for a fuel pump whine. As for pre-filling the fuel filter, why would anyone pre-fill a fuel filter with contaminated fuel? I only use clean fuel from a clean container.
This is why I never diagnose a problem without seeing the boat or motor in person, because there is never an absolute "this is what causes the problem". Machines are dynamic, many factors influence many other factors. Just an FYI, I am Volvo trained, Honda Trained, Indmar and Ilmor as well. I've been doing this for 43 years.
Let’s see YOUR videos.
