Edelbrock Pro-Flo 4 Fuel injection on the Chevelle

- Today we make a massive upgrade to the 1965 Malibu SS by installing Fuel Injection to the small block Chevy 350. We will be using a high pressure fuel pump mounted near the tank, a copper nickel pressure supply line, pre and post pump fuel filters and a return line back to the gas tank.
If you have a project you would like to showcase at the end of one of my videos just email me a few pics and a short description to: foothillpaintandfabrication@gmail.com
Nice work Mark. I'm a carburetor guy but I see the beauty of fuel injection for a street car or daily driver. I like how they say plug and play like there is nothing else to do. Thank you for your time.
Thanks. I know a few carb guys that scoff at fuel injection but they sure like it on their daily driver. This system is supposed to be able to go up to about 950 hp with bigger injectors.
@@FoothillPaintandFabrication I have nothing against EFI. Other than my 67 Cadillac hearse and my 53 race truck all my vehicles are fuel injected.
@@lazyhoundracing9621 Hearse? Do you have a side job I don't know about???
@@FoothillPaintandFabrication About 30 years ago I was building an addition on a nursing home and the engine blew up in my work truck. I bought the hearse for $500 to use as a work truck while I rebuilt the engine. It's roomy. I fell in love with it and couldn't let it go. The director of the nursing home was not impressed and made me use the back gate. I load it up with zombies on Halloween and hit the haunted houses.
@@lazyhoundracing9621 That is awesome!
Just add a return line directly to the tank , thats the rite way to do it , !!!!
Always enjoy when the Chevelle is on the channel!!!
Nice change of pace for sure. John wants it painted red but I am busy with Ruby and he needs to save lots of 💰
Hi Mark, nice to see the 65 again. I plan on using efi on my El Camino. Thanks for including the “stumbling blocks” in the video. Great job as usual.
Thanks Steve. If any trouble comes up on the system I will let you know.
Great video. I just ordered the ProFlo 4 for my ‘70 Chevelle SS 396 project. I already have a Tanks Inc. gas tank with an in tank fuel pump. Hopefully that will help me avoid some of the issues you ran into. Also, I’m replacing the factory 1/4” return line with a 3/8” line to match the feed line. I was wondering can you run the fuel lines to the back of the intake for a cleaner look.
Hi Ryan and thanks.
Yes you can easily swap the cross over line from the back to the front and put your pressure in and regulator out in the back. The Edelbrock regulator works well but may pose a space problem at the back of the fuel rail. A remote regulator would work just as well too.
The larger return line is a good idea.
I had a problem with a 67 Chevelle I installed this system on because the vibration dampener had shifted over all those years so the timing mark was way off so when I set the ignition timing to 12 degrees before top dead center it was very retarded badly. So bad that the exhaust manifolds ran cherry red at idle. Ended up cooking a brand new set of plug wires before I figured out what the problem was. If you are running your original dampener confirm the timing mark has not moved.
Good luck on your build and let me know if you have any questions.
@@FoothillPaintandFabrication thanks for the advice. The install doesn’t seem as daunting after your video. I still have a ways to go to get started on the install though. Got to get the frame painted and the body back on first
I have the pro Flo 4 app on my phone but under the “E tuner Display” yours has a speedo and tach. Mine only has a tach and it’s just a basic graph style. It doesn’t look like an actual gauge like yours. Are you using the E tuner 4 app? I can view my speed on the transmission app but that one is separate for the trans controller they sell.
@@jarrettb.7302 Yes I downloaded the newest version I think. When I select the E Tuner display it asks to use my phone's location services so the MPH must get its signal from GPS on the phone.
I am using an Android with the latest OS.
@@FoothillPaintandFabrication I see. I’m on iPhone so the android and iPhone apps must be different. Thats pretty unfortunate.
@@jarrettb.7302 Android wins again!
It is a nice feature, maybe they will add it soon.
I am planning on getting an aftermarket TBI for the panel truck. After seeing the hassle you went through with the return line I (hopefully) am glad I retrofitted my existing gas tank with an in tank electric pump from Speedway Motors.
I'll want to use the braided steel lines so thanks for sharing how to fabricate them. Is that a kit you purchased to make them up?
Another excellent video Mark. Thanks
Thanks
Does your in tank pump have a built in regulator to bleed off the extra pressure?
Yes we got a kit from Amazon with 6an hose and fittings. If you are planning on running pump gas then there are a ton of options on there with hose and fittings. Here are two links: a.co/d/6fqsGNe
a.co/d/84Emqap
Throttle body units are a lot less expensive and less work with some nice benefits.
No it doesn't. That's my next step to get a regulator (once I have a permanent fender panel to put it on).
Thanks so much for the link! I put the black braided hose kit on my Amazon wish list.
@@BusyAsABeaver72 Ah those pesky details...
Getting a good cut without fraying the braid is the tricky part. I walk the cut off wheel around the hose kind of like a pipe cutter so the wheel cuts down into the braid through the black tape.
Hi Mark, hope you’re doing well. Still working on my 64 Malibu SS here in Florida. Just watched your video on the fuel injection install on the 65 Malibu. You mentioned the electric fuel pump you are using is very quiet. For my carbureted 327 I’m using a Holley 670 with an edelbrock electric pump. This seems to be working well but the pump is a little too loud for my liking. Do you know of one that might be a bit quieter ?
Noisy fuel pumps are the worst! We used a Walbro inline pump and although you can hear it with the key on and engine off you cannot hear it with the engine running. I did my best to isolate it though. The Edelbrock pump looks a lot like the Walbro unit so I don't know if they are just repackaging theirs and tripling the cost or not. I have been told the Holley pump is crazy load so avoid theirs. How do you have the fuel pump mounted?
I used isolaters between the pump and the frame. I don’t have a return line and that concerns me for longevity of the pump. I agree with what you said though, when the engine is running I can’t hear it so at this time I’ll likely keep it as it is. In your opinion is there really an advantage using an electric pump vs. a mechanical one on a street driven car ?
@@davidrosenthal735 For non fuel injection cars a mechanical pump is more than sufficient as long as it can keep up with the carburetor. Are you running a fuel regulator?
No, I am not running a fuel pressure regulator. This all got started when I noticed my fuel pressure gauge was showing about 6psi at a cold start. After the engine warmed up the pressure dropped to zero. I changed my mechanical fuel pump at least three times. I decided to install an electrical pump, no change. I put a 1/2” phenolic spacer between the carburetor and the intake still not a fix. After the gauge drops to zero there is no change to the engine, it continues to run fine. So confused.
@@davidrosenthal735 Very strange. The psi on the electric pump should be much higher. I wonder if the gauge or plumbing to the gauge is faulty. Could be vapor lock but that is unlikely to just start happening but it might be worth a look to see if any fuel lines are too close to a heat source. Is the tank vented well? Has there been a change to anything else prior to this fuel pressure problem?
