your opinions on a streetable 500+ rwhp fuel system
 

Hi guys. Im looking into my fuel system to supply good fuel for my 500-600 whp street setup. Im debating on doing the dual intank system or sump my tank and run inline fuel pump ect. What do you guys think?

You could run a single pump that will get you in the 500+ range, Bosch 044, aeromotive stealth 340, or walbro 400 pump. I have a dual intank Aeromotive 340 setup that might be selling, thinking about going with a sump setup.

I say run new fuel lines with a swirl pot, an 044 (or similar) inline, and a better (FuelLab) fuel filter. Run a -8 line from the tank to the engine bay, then split to -6 line(s) run in parallel to ID1000/ID2000 injectors, with a -6 returning to your swirl pot/tank.

It ain't cheap, but you'll only need to do it once.

Im running an xcessive manifold and was just going to rum 750 cc bosch injectors primary and 1680 cc bosch for secondary in the same rail. And run a bosch 044 inline with an aeromotive inline filter. Woulf that be good enough for my max goal of 600? I can always run the primary rail also if more was needed. And just run 4 secondary injectors.

Let me ask you a question. How much are you bothered by the fact that, without significant modification, you need to keep your gas tank above about 1/3 full or the sheer torque of that kind of setup will make severe tank slosh?

If you're willing to always keep your tank at least 1/3-1/2 full, I would not make any modifications to the tank itself. Furthermore, the simple fuel systems seem to be the most reliable over time. 4 injectors, 1 drop-in pump, no complicated parallel fuel lines and all that. You'll find a lot of guys over the years spending tons of money on a complicated and expensive system that they're always troubleshooting.

I would love to drop in a pump in my tank and run aftermarket filter and thats it. Lol. I did lots of research and everybody swears that you need to run dual pumps or aftermarket inline. If I can just drop in a pump. Do the relay modification. Run feed line into my single fuel rail I would be golden. I want it as simple as possible but be able to support 600... question to you guys. Would 760 cc primarys and 1680 cc secondarys hold my hp range?

From my past experiences, most likely not.

Within the past 2 years or so, higher flow drop-in pumps (Aeromotive, Walbro) have come out and so have higher flow injectors (2200cc high impedence). That's the difference. Furthermore, 500whp is absolutely insane ans barely usable on the street. You may find yourself stopping at 400. 420 on pump fuel only was plenty for me... that was with 720/1680, Supra pump, no parallel lines or anything like that.

Well I want the option of raising the boost and getting 550 when I need it. But deff lower the boost when street driving.

When do you foresee "needing" 550whp? As arghx suggested, pretty much anything 450+ is scary fast..

At the track lol. Im not scared of power.

If you're drag racing than whatever, but if you're talking about an actual track, with turns in it, than I think it's been proven by several members on here that you don't *need* more horsepower to be good.

Either way, if you're looking for a badass fuel delivery system that will support pretty much anything you're able to make than try what I suggested and consider the PTFE/Teflon lines and fittings.

I would suggest:

15' -8 steel braided line
15' -6 steel braided line (return line)
10' -6 nylon braided line (fuel lines inside engine bay)
1x 90* -8 bulkhead fitting
1x 90* -6 bulkhead fitting
3x 180* -6 hose ends
2x 120* -6 hose ends
2x 90* -6 hose ends
2x 45* -6 hose ends
1x straight -6 fitting (3x if doing a swirl pot)
4x straight -8 hose ends (6x if doing swirl pot)
1x -8 to dual -6 y-connector
1x -8 fuel filter (FuelLab has a nice one that comes with mounting straps)

Also, I'd go with the FFE Primary/Secondary rail combo. If you buy them and injectors (again, ID1000/ID2000) at the same time than they will cut you a discount on the injectors.

There is your shopping list, feel free to check my build thread on RCC if you want to see details. I would link you to it, but they block (and ban for) directly linking threads there.
