i'm looking to replumb the fuel system on my 93 C2500 pickup. initially i looked into prebent stainless lines, which would run me roughly $370 plus shipping for prebent lines (which i'll have to modify slightly anyways to clear my SAS brackets). so i then turned to looking at braided stainless lines. i figure i can do braided stainless lines, along with an Aeromotive AFPR for just a little cheaper.

here's what i've come up with so far...

-6AN hose for both pressure and return lines.
20' should be enough, but i may buy a little extra, just to be on the safe side.

Aeromotive 13301 regulator

Earl's 230106 fuel filter. filters to 35 microns, max pressure 75psi, so i shouldnt have much problem there since im only planning on running TBI.

6 -6AN hose ends, two for eact of the 3 lines (tank to tb, tb to reg, reg to tank). does anyone know if these fittings will swivel as they're tightened, or will the entire hose spin as it is tightened?

2 3/8 NPT to -6AN adapters for the regulator

and then a 0-60psi gauge to fit to the AFPR.

and then the 4 adapters required to adapt my stock TB, and my stock fuel tank sender to the -6AN lines.

also looking to plumb the trans lines in stainless as well. can anyone point me in the right direction for the adapter to go from a double flare fitting to the AN hose?

I want to do the same thing to my firebird this summer.

I dont see any reason to run braided line all the way to the tank, unless your steel lines are rotted. I was looking at it today, and the steel lines look like they un-bolt over near the charcoal canister. So, just figure out the fitting you would need, and run one braided line from the canister outlet line, to the TBI inlet. Then, run another line from the TBI outlet, to the aeromotive VAFPR. Finally, run one from the VAFPR to the steel return line over by the charcoal canister. On my car, I would say 10ft of line would suffice.

For the guage, I would get the aeromotive 0-15PSI guage. Unless you plan on running massive pressure to the TBI for PROM burning reasons. I would say 15 would be plenty of fuel, almost too much I think.

Do you know how much PSI the regualtor will drop, with say, regular vacuum at highway cruise? I would ideally like something about 10 or 11 psi at cruise, for gas milage. Then when you crack the throttle, it could jump up to about 13-14. That would be nice.

-----------------------------

The only thing I haven't found yet, is the stock FPR. I was looking at the TB today, and couldnt see where it is, to take it out. I guess you gotta make some "block off plate" to replace the stock FPR, but that shouldnt be too hard with a thin plate of aluminum, and a drill.

the fittings on the ends of my lines were seized to the line, so the only way to remove them was to twist them off. i'm doing a full frame up build on this truck, so removal of all of the components was necessary. they were pretty crusty anyways, and whats the point of using old crusty lines on a truck thats virtually new from the ground up?

going with the 0-60 gauge because i'm planning on getting into tuning on the TBI, though initially it will have the stock 350 back under the hood.

not sure exactly how the vacuum works on this one, there are plenty of guys at www.fullsizechevy.com running the regulator, might try there.

bypassing the FPR just requires removing the spring and washer, IIRC.

You could use new alum/stainless along the frame. then Aeroquip sells a compression fitting adapter to attach whatever. I did that. My lines end just inside the air conditioning compressor. Now consider the Aeroquip synthetic "socketless" EFI rated hose. It comes in black(i like) or blue. you heat the end of hose in water and press fit the barbed fitting into it. when cool down rated I think to 300 psi. Reusable and I did. Heat resistent. Mine lays on manifold. I think a bit more in cost however.
