1g fuel pump in a 2g......are they interchangeble?

[GlenMartin]

i have a aftermarket 255 lph holley pump kicking around for a 1g. i believe a 90-92. the pump is actually sitting at my bro's house. can i stick this in my talon? which is a 95 tsi.

[John Hartman]

you will have to rig it up "Mustang" style as it won't have all the correct fittings, but you can make it work.

[Brett Haviland]

the 1g walbro kits use a 2g or "universal" style pump.  The 1G kits just come with a wiring adapter to make it work with the 2g style wiring.  

SO yes, The 1g 255 lph walbro pump will fit perfectly into your 2G. or it should anyways.

i not sure about the fittings john is talking about?? dont the  2G's just use a "hat and o'ring" to seal off the top pump outlet where 1G use a hose over the outlet... but i could be wrong here.  I have been wrong about rear o2 sensors affecting fuel trims before!

i think i compared a "1g" and "2G" dsm kit before.  they were idential besides the wiring adapter in the 1g kit and extra piece of hose/clamps and small oring.  they should both also come with a neopreme "sock" or whatever and a hose clamp i beleieve.

I've never actually put one in a DSM, but apparently if you hook it up with a universal pump, it won't hold pressure when the key is off?  And if its hooked up with the correct parts, it will?

I asked Lowell about this once when he did my pump WAY back in the day 

Also Marke and I were talking about it and his is hooked up "Mustang" style and he has to crank it a little to build up pressure whereas mine (at least it used to, I think the little check valve has bit it) would crank on one or less crank rotations sometimes.

But like I said, I have never actually put a pump in Dizzm.  TONS of other cars, but never one of these.

[GlenMartin]

i think all you guys did was confuse me. it will work? but it wont work? your suppose to have pressure when the key is turned off? what? you guys be crazy.

[Brett Haviland]

it will work glen. and it will support 400ish HP too with a re-wire, maybe even without!! haha

for fuck sakes......so vague. i think your saying with the ground wire mod thing right.

[Graeme H Burvill]

Seems like it just may need some special wiring, such as the 1g wiring kit or something similar. Or you could just sell it and get one that will drop right in.

I am begining to think this might be the best option..........anyone need one?

[Brett Haviland]

jeeze!! if its 1g KIt it WILL fit right into a 2G.  okay? NO WIRING REQUIRED!

IT WILL WORK FINE!  (simple enough?)

[Phil Maki]

OK this is it!

1g FWD pump only = 2G pumps (both fwd and awd)
1g AWD is it's own.

it's all about the inlet and outlet positions to the pump.

The installation kits are specific to each model.

yayyy  i never knew the fwd pumps differed from the awd pumps (1g)

[GlenMartin]

ok so that means i need to sell mine.......right?? brand new never used. offers? what are these worth?

[Brett Haviland]

Glen:

was the walbro pumpyou have, was it originally going into that old beat up maroon awd 1G that your brother had?? It was AWD if i remember corretly.  If it was... then the pump you have should work!
