Fuel system question

[justin]

I'm trying to plan out my fuel system for when I do the turbo install in a few months. Originally, I was planning running -6 SS line for the fuel feed (2001 Integra GSR btw). After looking through my Helms lastnight I realized that it may not be much more efficient to go that route.

The older Integras have a banjo style fitting on the fuel pump bracket that connected to the stock steel feed line. Obviously removing the banjo fitting and running SS line all the way to the fuel filter was a better option, since the restrictive banjo fitting was out of the picture.

Now, on my car, I don't have that banjo fitting. There is a steel tube that sticks out of the fuel pump bracket that hooks up to "quick connect" fuel feed line that heads up to the fllter. It looks almost identical to the fuel return hookup. Should I just leave these lines stock as they are for <10psi?

I have post on h-t.com with pictures to use as examples if you want to take a look. Nobody over there felt like replying to my thread. Thanks for any help.

-6an would almost be stock. I used -8an feed an -6an stock.
I ditched the stock fuel filter and am using an earls in between the pump and tank, and an sx filter between the pump and rail.
I just ran one length of stainless line to the filter, from thte filter to the rail, and from the rail to the regulator and back.
Just used a bunch of AN fittings to connect it all.
If you want more specific then that lemme know, I can give you a list of what I used.

Hmm, see that is another thing I was considering, doing it -8an instead of -6. Would it be at all detrimental (sp?) to run the -8 feed when only boosting up to 8psi? I don't *plan* on building my motor until summer (or later) of 2003. I was thinking that it might be overkill to run the bigger line with such little boost.

I have an Aeromotive filter to use between the rail (aem) and pump (which I don't have yet). But no filter for between the tank and pump. I have an Aeromotive FPR for the other rail side too. Plus I sketched out a schematic of the setup which includes all the AN fittings I need to buy :P

Really my only dilemma is whether or not to run the SS line (-6 or -8) or leave it stock. I also do not know exactly how I would connect the SS feed to the pump and how I would drop the return back in the tank.

Your help/suggestions is much appreciated.

honestly, if you plan on staying at 8psi i wouldn't worry about the lines from the tank to the filter and shit. What you could to is just redo all the engine bay hoses and fitting with AN fittings because the banjo bolts are going to cause your loss in flow more then the lines would. I have it written down somewhere what an fitting you can buy that will thread right into the stock fuel filter. then just run some stainless line from that to your rail and back.

For the return line, you can drill out the stock retrun fitting and use a AN bulkhead and nut to take it's place. Same goes for the feed. I used some rubber line and some copper tube to connect to the stock pickup.

But the reason I did everything like that was so I'd know fuel would not be a problem. If you know your going to go bigger, you might as well take care of everything at once you know?
so you'll never have to wonder if your fuel system will support your motor and shit.

Hmm, I hate decisions that just itch on me like this :rolleyes: I do plan on going with more boost down the road. But I think for now I'm going to leave the lines stock and use the stock fuel filter like you mentioned. I know what AN part I need also to hook up to the filter. This is probably the better choice to start off with anyways, one less thing to go wrong after the turbo and everything is installed.

I'll save this pretty red Aeromotive fuel filter for down the road when I upgrade the lines to SS everywhere :) Thanks for the help.

Oh yea, you think I should I upgrade the in-tank fuel pump too? I don't exactly which kind I should go wih. I'm going to be running 450cc DSM injectors if it makes a difference.

Yeah dude, don't sweat the small shit. The line from the tank to the filter is no biggie, I'd leave it for now. The ones that suck are the return lines, and they're a lot cheaper to replace-- I keep on having the line between my FPR and my FMU break, it's not a good situation--

First time, the line split completely open, sprayed fuel on my windsheild (to mock me) then the "front" (driver side) of the motor caught on fire, to be extinguished under C-470 on Broadway by my Red Robin work shirt and a bottle of Arrowhead water that this nice lady in a Jetta provided me with. I'm forever in debt to women driving white Jettas.

Next time it happened, I was in the middle of No where in NW Arizona/SW Utah. I smelled fuel. Good thing my car didn't catch this time, I would have only been able to see the whole thing burn.

It happened again the other night on C-470 east of university. I caught it early again. I bought some SS line to replace it, and it's fine now.

Ugh, that doesn't sound like fun. I just gotta order up the rest of my AN fittings and SS line and I'll be good to go for that stuff. Planning on ordering the rest of the turbo stuff next month :)

I would leave the lines alone. I ran a new Steel braided from the filter to my inline pump, then to the rail. I had it custom built and retained the banjo's on each end.

You running an FMU then I am guessing? I will be running SS line from my filter to the rail, then from teh rail to my adjustable FPR. Other than that the lines will be stock.

I also still haven't figured out what kind of intank fuel pump I should get. I was thinking a Walbro but I'm not sure which model? I will be running Hondata as well. Anyone suggest a fuel pump to go with??

Walbro GSS-342 is the 255lph fuel pump you probably want.

If you want a good price on it, contact Jim Helbing at 205-661-3600
