EFI and Boost Fuel Pressure Regulators: Motion360

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?

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.

Awesome video! Great Info!

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?

Does running a fuel cooler/chiller helps with performance and hp?

What about mounting the FPR onto the fuel rail it self?

Is there a specific reason as to why the line criss-cross into the regulator??

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?

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 😅

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!

What about a carb setup with twin turbos..

Best video yet for me ... I screenshot your way of running this set up

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

Dose this work with a sheet metal intake ? With a truck water pump

What degree fittings are on the fuel regulator?

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??

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.

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

Keep loving your videos 😄

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.

Great video. 👍

Awesome video

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.*

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...

In a 2006 non return fuel, where and how do we put the return line please?

will the rh head mount work with a a1000 and a OE plastic intake as far has line and fittings routing ?

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.

Great video! What are the spacers called? And what angle fittings coming directly off the regulator? Also where is the return?

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 ?

Will this fit under a sheet metal eBay special?

Only reason I subscribed and liked this video is because of how detailed this man is thank you much obliged👌

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?

What about regulator and fuel heat? And scrapped fuel return for a Gen V LT1

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

Thank you

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. 🥴
