Return style Fuel system

[noshine4mine]

Wondering what other people did with a 2018+ car with the regulators. Did you go dual or a single fuel pressure regulator? What size feed line and return line?
I am leaning towards -8 feed and -6 return.
Has anyone installed one that wasn't a kit? How much hose did you buy (lengths)?


Thanks,

I would check out our DivisonX fuel system line! I like the dual regulator set up. We offer 10an feeds and 8an return lines with PTFE lines which are E85 approved. Send me a message and I can get a system specially tailored for your car and go over pricing. www.lethalperformance.com

I built one using a DW X2 hat. Ordered 15ft of -10AN for the main feed and 20ft of -8AN for the rest of the system. Single regulator setup. If I did it over I'd probably stick with -8an for the feed. The -10an was on sale at the time and was cheaper than -8 for the same length, its the only reason I went with -10.

Fore, single regulator, upgrading to triple pump and dual reg soon.

Holy shit, this is some good info. May I ask what your reasoning for wanting to use -8 instead? I am in that boat right now. I can get -10 and kind of want to for future expansion but I might just be over thinking it. My car is a street car not a dedicated dragster.

I have no intention of running e85 (closest Pump is an hour away). so I got a DW dual Hat too. I will be using Meth in the future, which wont increase the load on the fuel system to achieve higher power levels.

Found out today my tuner preferred Dual regulators, so that is what im doing.

-8 feed to the rails will support 1100-1200whp @ 75psi of pressure all day.

-8 feed to the rails will support 1100-1200whp @ 75psi of pressure all day.

It'll support much more than that if you beat on the fuel hard enough

For others, the reason you go larger with delivery (and return) components is to reduce the restriction and pressure drop between the pump and the injector. You can supply fuel to a 2000 hp motor through a 6 AN if you want, it just means the pumps have to operate at a higher pressure in order to deliver the desired pressure at the regulator/rails.

A general rule of thumb in hydrodynamics is that with fluid mechanical systems through piping, if you double the diameter, at the same pressure, you increase the flow nearly 8 times.

You don't need a 10 AN feed. You don't even NEED an 8AN feed. But it helps when optimizing the fuel system and pump sizing so you don't need to oversize the pumps as much.

In reality, the difference between an 8AN feed and a 10AN feed for most people is a couple PSI pressure drop difference at most and half of that coming from the filter (10AN filter size flows considerably better than an 8AN).

The other thing to consider is the "choke point" concept. Most guys don't even realize that upsizing between larger piping components helps, but if you have a choke point at any portion of the system, the rest of the upsizing is almost useless. What does that mean? It means if you're trying to water your lawn, you could have 20" diameter piping everywhere but if you're pushing the water through a coffee straw at the start, it ain't going to make an appreciable difference.

This comes into play in quite a few of the aftermarket fuel hats. The "manifold" that's used to combine the fuel feeds from multiple pumps can sometimes be a very small restriction (like 3/16"). Every little improvement helps, but for most guys, it's a non factor.

The whipple fuel rails are tiny compared to most aftermarket rails and guys make plenty of power with them. The pumps just have to run slightly higher pressure.

fore single regulator system here. I am getting a ton of pulsing on the pressure gauge at idle, swinging from 30 to 60 basically. The pulsing smooths out with rpm is this correct?

I don’t have a fore setup but that does not sound normal. My fuel pressure holds steady at idle.

What is the regulator set at?

Thanks,

Single or dual both work fine. we actually run the single on our shop car. 1500 wheel,

Fore is what you want, they are a fuel system company, they make fuel systems, everything machined in house other than a few oddball fittings.

Only thing they don't make is the pumps and the lines.

8 feed / return on most setups unless your going like 1200 plus.

level 1 e handles pretty much most of the average guys and our best seller on that.

Fore is a fuel system company, not a retailer like me piecing together parts to make more margin.

I would rather make less and deliver a quality part from a company thats going to stand behind it 100%. You won't find a better bunch of guys than Justin and his crew at fore.

2018+ I run duals.
2017 and lower, singles.

Just my personal preference. I enjoy the stability of the pressure with the duals on the DI cars. (lotta noise in the DI pump that can turn into feedback)

What is the regulator set at?

58 lbs. as far as I know. Shop did system install and tune. Shop says logs are fine, communicating with fore currently. Sounds like lots of guys have this problem to some extent. It is swinging from 30 to 50 after re watching my video.

It should not be fluctuating like that something is definitely not right. When I had a single FPR it held steady just as my dual ones do now when at idle.
