Another ideea for you would be instead of haveing a return line that you have to hookup to the fuel rail just assemble your pumps and fuel preasure regulator under the driver side passenger seat were you get to your stock fuel pump. You can make the settup alot more isolated in one area and have to run less fuel line. It works the same and it seems to be the settup my buddys like. Hell, there putting down 850 to the wheels no problems.

can i use FPR before the rails? i thought we used that right after the rails. i think i'll be using stock fuel lines & evap lines for the returns.

One side mount.... Thats nonesense. You need both sides, your engine will produce lots of torque. Do not finish your swap with only one mount, specially if its on the side like ours. About the fuel setup, I dont see it een a good idea to keep the stock pump to provide fuel for the other 2. Think about it, you will have two pumps sucking lots of fuel.

stickmantijuana

o i think i see what you mean. it's a great idea, but i think it'll be little too noisy right under the seats...?

stickmantijuana

thanks joel. about the pump capacity though, i'll have return line to the sump tank directly.

is your setup same as pr guy's? i think they said replace the stock pump with 023 and run that to the primary rail, and external 044 to the secondary rale. return using the same return line but back into the fuel tank, not the evap tank.

Moon Assad

Yeh, just run it like this fuel supply, fuel pump, filter, T for supply to fuel rail, preasure regulator, return to tank. As for the transfer in the tank, you should be fine but you might want to put in a fuel preasure sensor so if it does fail you now it when you loss preasure.

angeljoelv

Lets assume you have a large sump tank and it fills up while your car is iddling, Now you deside to go on the highway and step on your car to see how fast you can go. Now your two pumps will be sucking fuel at a rate your |OEM pump will never be able to keep up. In other woeds, im not worried about the pump not working at regular driving, Im worried about when you want to have fun.

Thats a different story... That wont be the OEM pump... I like that..

angeljoelv

Hey stick... If you need pics, PM with what you need. Ill take all the pics you want from mine and send them to you...

stickmantijuana

i thought 2gal would be enough to have "fun" often while giving oem pump time to "catch-up" when i'm slowing down after accelerating at WOT. i may have to rethink the design.

moon, which pump is your friend using that's supporting 850hp? i like that setup alot, but i couldnt' find any pumps that'd be quiet and support that much flow by itself.

stickmantijuana

thanks joel. whenever you get a chance, your pump mount, location, any modification made to the original tank and basic info of your setup would be really helpful. no hurries.

angeljoelv

Yea but if you change the OEM to a better one you will be fine

angeljoelv

You dont even need to leave the feeding pump in the stock place. ( I dont have it there)

Moon Assad

Its prettymuch like the stock settup but outside of the tank. Just leave the purge system open under the hood to relieve tank pressure. We ran all of our prototype blower kits with it open so theres no vapor problems to worry about.

angeljoelv

If you ever have a chance you can allways come to FL and take a look.. haha

stickmantijuana

haha, sounds fun joel. so i'm guessing just take the stock pump out and replace it with one bosch 044? if so, that's great news.

i guess you guys don't worry much about stock system that balances both sides of the fuel tank. i haven't taken it apart yet as i got a broken one from scott, but i'm assuming, just take the stock pump out, hook up send line to the 044, and that's it?

some close-up photos of this mod would be really helpful...

angeljoelv

no no no... you do have to worry about that. Thats why my set up is outside the tank. I just took my OEM pump out. Everything else tays the same... It has to or iyt wont work properly. Ill try to take pics and show you. I wont be taking the set up out for now though so there is not that much I can show you from the outside....
Its very simple, so simple I did it... hahaha you will see..

Ill swing buy Richys monday and ask him, it was on a 2nd gen, hes gotten it into the 7s consistant, maybe the 6s once or 2wice. Have you gotten any leads on a lower intake yet???? If you need me to mod it for you so it sits lower im game. Cant tell you how much lower I can get it till I can look into it but you no what, for bragging rites you just might be able to talk me into a building one for you. Ill carve out the runners from solid stock. You just gotta pay for supplys and any tools I might need. Other then the before mentioned costs my time for you will be free. Itl be fun!!!!

stickmantijuana

oh okay. i think i see what you guys mean now. take out the oem pump. insert a self-priming external pump in the fuel line, run AN-10 to the rails, etc.

where are you dumping your return fuels? using stock line or custom one?

stickmantijuana

moon, sounds awesome. i plan on changing that LIM eventually, but just wanna get the engine rolling asap for now i'm hoping to crank it just before the spring! once it runs, i'll address other stuff, and LIM will definitely be on top of my list then. besides, just learning basics of fuel system took me all day. ehh probably shouldn't expand onto other areas just yet

angeljoelv

In my case Im using the stock fuel line for return. and I used my OEm return line as a breather conected to the intake with a Check valve.

stickmantijuana

thanks for this. this clears up tons of things. did you take out the evap system under the trunk? i'm guessing it's not doing anything anymore. before i take it out, i just wanted to make sure

so use the original fuel send line as return going right back into the driver-side tank. and connect the evap/purge line to the intake with a checkvalve. sounds excellent.

and i'd need to make just ONE drilled hole from the fuel tank (attached to the stock fuel plastic assembly without the stock oem pump) to the external pump pumping to the engine.

angeljoelv

I drilled right on the plastic cover. The only thing is my setup has two lines going out the tank. But it will still give you the idea.

angeljoelv

I dont know if somebody already said it but in my car I put a check vallve on my secondary pump, so that fuel only goes out. Mine opens at 5 psi of boost, so while is off there is no fuel pushed from the primary pump, thus lost in pressure...

Moon Assad

Just throwing you the idea to help with fitting your intake in the tunnle. Just a warnning, if someone isnt an expert welder you dont want to trust what shady tree welding can do. Most begginer welders (even expert welders do it from time to time) will turd. If you have a big gap in the materials you run alot more risk of turding through. If you have any turds they can break off through all the heat cycles and fall into your engine. I see alot of gaps in that intake you recieved, I wouldnt run it if I were you, you need to find a stock one and see what your clearence issues are before you continue. If you want me to build you one ill try my best to get it done before spring but im telling you it will be ****. Im not trying to make any money from you, I just want to see an awsome project finished rite.
