I was just reading my Holley High Ram instructions and you are exactly right! (from Holley) *The best configuration for plumbing the fuel rails is to split from the supply line with a “Y” type distribution block or fitting, then feed into the inlet end of each fuel rail. The hoses from the exit end of each fuel rail would then feed into each inlet port of a fuel pressure regulator with two inlet ports or into another “Y” type distribution block or fitting connecting to a hose leading to the fuel pressure regulator.*
Can I still do this for the boost ref., on a stock 99 Camaro ECU, or how much is this ecu going to limit me..? Not out to break records, just drive to Bradenton, bust off a 8.60 and drive it home with the a/c on! Thanks for your help and support for the automotive industry Doug, Andy, Garrett, and I'm sure a dozen or so more!! Yes, yall have been blessed doing what you love, but you've also started a world on TH-cam for guys who are afraid to DIY., maybe it makes em try..?? I know it took me a lot and I'd built cars for years!
Thank you for this video, I looked at a few other videos that were no where near as detailed! Really helped me understand it. Was mostly looking how the boost reference regulator worked. I have currently have a n/a carb’d ls, will be switching to efi and twin turbos (big change in all my components) pretty much have to redo whole car haha. Shooting for 800whp with room to grow to 1200whp+ if I have to, which I mean come on it will happen eventually haha. I am definitely going to have to check some of your products out!
Doug, I am SUPER LATE with watching these tech videos. I have to say though u are dropping BOMBS 💣 of knowledge and sure correcting the mis education of going fast. The way u always say “with any part not just ours” says a lot. I am a big JEGS or SUMMIT RACING guy but I’m gonna start buying my parts from MOTION RACEWORKS. If the tech support is as good as in these videos I know I will NEVER go without the vital info I need to complete my project or any project I work on. Looking forward to buying from MOTION RACEWORKS and finishing my Camaro without too many issues. Keep up the GREAT SERVICE & GREAT VIDEOS. 👍🏽🙏. Headed to the website now to see what stuff I can buy and piss my wife off with buying more Hot Rod parts
oscar cabrera thank you for the kind words! We are just getting started too. Every single person at Motion is a passionate and knowledgeable enthusiast. We appreciate your support!
Any way you can do a video of making and hooking up a return line for a plastic tank that didn't have a return line for some of us please? Have an 06 silverado and didn't have a return line but wanna put one like you explain in this video.
I know this is an old video so IDK if you'll see this, but if you want to run #10 from the pump to the rails, where are you finding fuel rails with #10 ports? Everything I see is #6. May be a dumb question, but I'll risk it.
I have F.A.S.T SMART INJECTION TBI ,Just bought a Aeromotive A1000 pump .do I set the F.A.S.T REGULATOR aside and get the AEROMOTIVE REG,and I had a 500 hoss LS1 went from the pump to the REGULATOR from the REGULATOR to the T.B.l ,so I've yanked the LS1, and a Texas Speed 427 Stroker is taking its place,,,,is why I went to the Aeromotive A1000 to get a Solid 59 psi, so run AN 10 from the Tank to the pump from the pump to the REGULATOR and AN 10 Return Line as well ?
Doing -8 feed from tank to the rails should i keep all the rest of the connnections to the fpr -8 aswell or will using -6 give me pressure issues? Using -6 for the return aswell
I apologise, I know this is an older video however I do have one question.... I was previously running my boost reference straight from a charge pipe, now I have your distribution block and wanted to use that as a source for my fpr. Will I have any issues with the fpr now seeing vacuum??
Ok, one big problem about running in series. You’re wrong about that. Explain how one bank runs more lean than the other when the regulator is showing the correct psi for your application. Because pressure being pressure means the system is full. And the regulator is reading from the fuel pump to the regulator. So the ENTIRE system is seeing the desired amount of fuel. And if your pump is strong enough that pressure drop shouldn’t be an issue. And in all actually running parallel might actually have a higher chance of what you’re afraid of happening because one source has to fill up 2 zones. Theoretically the fuel would move slower after the y because of the pressure drop. Only way I’d run parallel is if I had two feed sources.
But that would be assuming pressure wasn’t involved in both instances. On the initial starting of the pump would be the only time the issue would/should occur. I think you need to make a video with transparent rails on startup. That way you can time which one takes longer and by how much to fill the rails.
Tommy Hathaway would love to setup some test benches on this! The issue would be considering that the pump is completely running out of capability. It’s going to burn those cylinders out much worse. Rather than the entire engine going lean. With an averaging O2 there are going to be some very starved cylinders. If maxing out pumps is never an issue and pressure can be carried than that is something that doesn’t necessarily apply
Motion Raceworks Official gotcha gotcha. I feel it. Apologies if I came off standoffish. Lol My main concern was with the video saying series was a flawed setup. They both have advantages and disadvantages. And you touched on what I was saying about the pump maintaining volume and pressure. But I completely feel you. In the even of a failure one bank would see more damage in the in the short time before running out of fuel. However, I do feel like parallel would burn two identical cylinders on front or back. And I’m asking to make sure my facts are straight. If anything I’d like to learn something new.
blockequals4 lol I’m just trying to have an intellectual conversation. Like I said, my bad if I came off upset or something. I’m just making sure I understand clearly. I’m good.
I am thinking of fitting an Edelbrock Pro-Flo 4 system. Edelbrock suggest that I loop the fuel rails (the opposite of what you suggest) and fit a fuel pressure sensor at the end of the second fuel rail. If I do as you suggest where would you permanently mount the fuel pressure sensor? Perhaps on the fuel regulator?
Crap! I thought I had it right because Regulator is after, but I did the loop around. The worst part about learning something new, is when it sounds completely obvious. 🥴
Im sure you are going to tell me to call.. But I will be running a 4.5L whipple and don't think I will have the room to run the regulator in the front like that. its a 427LS at first I only plan on running 15lbs of boost on pump gas, and then might switch to about 23lbs on E85 . the pumps are in-tank and triple 450 setup.. Suggestions?
RRM Garage you can mount it where works for you except fire wall. The main thing he’s getting at is pump feed lines then t in y fitting to each rail then into reg and then return. I’d prob do -10 feed y’d off to rails with -8, then from rails to the reg with -8 and a -8 or -10 return to tank. That may be considered overkill for pump gas but with a 427 and a big Whipple you will prob eventually want to hose it down with some e85 and of course it needs more volume. Hope that helps. Better to have more than not enough fuel system. The line sizing I described should be enough to run out that blower. Stay safe out there patriot.
RRM Garage absolutely! As brad said. You can certainly put the regulator elsewhere. Just make sure to feed the rails before you go into the regulator. Hope that makes sense. Feed the front of the rails with the feed line via y and fittings and have the regulator AFTER, but in the back.
Thanks Brad, that is pretty much what I was already thinking. As far as the E85 goes Ill probably throw some in after I get done with RMRW. Get that power up there a ways to see how fast she will go, I've kinda become interested in one of those Motion stickers. lol
Damn man, I’m questioning my fuel set up now. We run N/A on E85 carburetor. Should we be running into the fuel rail and then to the regulator? I’ve never heard that but we don’t run a booster application either.
nice video, I do disagree with a couple of things though, the return line size being large isn't always going to bring your fuel back to the tank faster, the volume of flow you are pushing through the line is going to determine the flow rate back into the tank along with a whole bunch of other variables. (meaning how much fuel is actually being used by the engine before returning plus the rate of your fuel pumps and the pressure). Phenolic spacers are a good heat barrier but after prolonged use they will transfer the heat just as easily as metal. Aluminum just has a much higher specific heat than phenol resin. Fuel increasing temperature could be a lot of variables including the routing method, the type of connections being used, the material of the lines and their proximity to other things that may cause it to increase in temperature (like you said exhaust). Thankfully ceramic coating is taking off in the automotive world, because for many years people have believed that anodizing aluminum parts changes the emissivity of the material (especially when it's black). it was mostly used as a corrosion barrier. (The myth about black coated intercoolers not heat soaking).
Great info. Im running a magnafuel 750 in-tank right now with a -8 feed - running in series at the rail to a magnafuel 1:1 regulator. Then -6 back to the tank. Do you think this would be alright to get 6 maybe 700hp (whp) with e-85? Or should I go ahead and switch to a parallel setup?
Only reason I subscribed and liked this video is because of how detailed this man is thank you much obliged👌

Can’t tell you how much these videos are helping me. These and speaking with Dalton have been invaluable in my build.
Thank you

Best video yet for me ... I screenshot your way of running this set up
FYI the under intake one clears a TBSS intake with the upswept throttle body!! just picked one up. . . and Gushers are good for at least +5HP 😅
Califormula even with a factory truck water pump in place?????
Any way you can do a video of making and hooking up a return line for a plastic tank that didn't have a return line for some of us please? Have an 06 silverado and didn't have a return line but wanna put one like you explain in this video.
Don't know if you'll see this comment but this was great information. Do you guys ever sponsor smaller youtube guys?
Great video! What are the spacers called? And what angle fittings coming directly off the regulator? Also where is the return?
Awesome video! Great Info!
George Mitchell thanks sir!
What about regulator and fuel heat? And scrapped fuel return for a Gen V LT1
Will this fit under a sheet metal eBay special?
I know this is an old video so IDK if you'll see this, but if you want to run #10 from the pump to the rails, where are you finding fuel rails with #10 ports? Everything I see is #6. May be a dumb question, but I'll risk it.
In a 2006 non return fuel, where and how do we put the return line please?
I have F.A.S.T SMART INJECTION TBI ,Just bought a Aeromotive A1000 pump .do I set the F.A.S.T REGULATOR aside and get the AEROMOTIVE REG,and I had a 500 hoss LS1 went from the pump to the REGULATOR from the REGULATOR to the T.B.l ,so I've yanked the LS1, and a Texas Speed 427 Stroker is taking its place,,,,is why I went to the Aeromotive A1000 to get a Solid 59 psi, so run AN 10 from the Tank to the pump from the pump to the REGULATOR and AN 10 Return Line as well ?
Doing -8 feed from tank to the rails should i keep all the rest of the connnections to the fpr -8 aswell or will using -6 give me pressure issues? Using -6 for the return aswell
So if you run a 8an feed do you recommend the y into the rails step down to 6an? Or is it OK to just y into two 8an? Any benefits or cons either way?
Keep loving your videos 😄
will the rh head mount work with a a1000 and a OE plastic intake as far has line and fittings routing ?
Dose this work with a sheet metal intake ? With a truck water pump
What about a carb setup with twin turbos..
Is there a specific reason as to why the line criss-cross into the regulator??
robertcas2269 simply for aesthetics

James Barnes if it’s not an all out race setup that will work
Does running a fuel cooler/chiller helps with performance and hp?
zohan zoe it certainly can bring the fuel back down to a proper temp which makes tuning safer!
What about mounting the FPR onto the fuel rail it self?
ItzBueno4Wat you can and lots of people do. I have seen a few bounce and crack fittings tho. Build a mount or remote mount if possible
Crap! I thought I had it right because Regulator is after, but I did the loop around. The worst part about learning something new, is when it sounds completely obvious. 🥴
What degree fittings are on the fuel regulator?
150 degree

Damn man, I’m questioning my fuel set up now. We run N/A on E85 carburetor. Should we be running into the fuel rail and then to the regulator? I’ve never heard that but we don’t run a booster application either.
Motion race works: If I have a bigger fuel pump and running stock injectors, could this setup cause a p0300-code (misfire) in multiple cylinders...

Marc Clegg the main purpose of the return line size being larger is to get the fuel off the back of the diaphragm
That may be the case for that. But there a point where it can be too big.
Great info. Im running a magnafuel 750 in-tank right now with a -8 feed - running in series at the rail to a magnafuel 1:1 regulator. Then -6 back to the tank. Do you think this would be alright to get 6 maybe 700hp (whp) with e-85? Or should I go ahead and switch to a parallel setup?
98snakehorse I always like to Y them. It’s going to regulate better that way. However, you may be able to squeak by at that 6-700 hp as is.
Motion Raceworks Official thanks I may just split the feed to each rail then to be safe
