Dual fuel pumps in a 2g AWD

[blageo23]

I also am going to do a dual walbro setup on my 2g. This is what my single setup looks like with 6an lines

I used this part...

The only problem is with the 2G there is no alot of room. The top of the fuel pump nipple is sitting inside that AN fitting(with hose around it) and its still sits too low.

I have a spare sending unit and 2 spare walbros. So soon I am going to fab my own and not spend $500 on it :)

Just do it.

I'll machine you one for $499 lol.

Quick question, what would cause fuel pressure to drop quickly after the pump turns off? It goes from 40psi down to 0psi in less than 5 seconds, and it's done this for the past couple years. When I installed the 255 last weekend I made sure the o-ring was still in good shape. I also have an aftermarket FPR. Any ideas?

[blageo23]

Mine does the same thing!

Mine also doesn't hold pressure after shutting the car down, and most after market FPRs are suppose to hold like 20 psi for a few minutes correct?

I thought it was the o-ring as well but never really looked into much.

Check the adjustment screw on the top of your AFPR. I actually put thread sealer on mine after hearing about quite a few leaking. Otherwise yeah that o-ring is a possibility.

My gauge started working after I filled the tank for the first time. What would cause this, the type of 2g tank style? I've always been confused on how those work, does it have to suck gas from one side to the other? Why did it not work after a fuel pump install?

Time 1: 2-3 gallons of fuel left, fuel pump install
Time 2: 1-2 gallons of fuel left, drive home with gauge not working
Time 3: full tank, gauge works fine

I've read that you need almost 6 gallons for everything to work right with the siphon and everything, but why does it work when I'm below 6 gallons and driving?


I also figured out a way I can make the dual pumps fit, since the T fitting is the same size as the output on the walbro pumps, I can just seal one end of the T fitting up there instead of a pump, shouldn't be too difficult. Obviously it'll fit a bit better than my sloppy picture.

The float was probably just stuck, and the fresh tank of gas dislodged(sp?) it, so now it's reading the correct level again.

Your MSPaint skillz are incredible!

Well my fuel gauge was working fine, then on my way home last night the fuel level started dropping rapidly, I thought a line broke, then the level went up again, then down to zero. I think its an electrical issue with the main white plug, which would explain the erratic fuel pump power problems I've had the past year.
