i got a made in USA Walbro from FullThrottlespeed.com
as reccomended by Darth,
$99 plus $7 shipping, includes tank gasket, rubber tank ring seal, harness , sock, hose and clamps
its for a Buick, but it should all work good (so im told)
but the walbro is stamped made in USA
now,.. ive swapped tanks on a fiero before but ive never done a FP, just the assembly swap to a differant tank
how is the fuel return line adapted to the walbro?
i put a walbro in my GTP years back and i think it is tha same pump, but there was a brass nipple fitting to go into the pump for the return line
is the fiero setup the same?
i have the hole in the pump right next to the outlet
am i missing anything?
i would just hate to get it all apart and need somthing or have somthing wrong or missing

should i use the rubber hose instead of that other thing that is in the fieros assembly?
ive read thru some writeups but i dont see anything specific about the fuel return line for the fiero assembly
any help is appreaciated and will be rewarded with the all mighty + is possible

that looks the same as mine, i put one in an 88gt. i just dropped the tank, real easy, and used a screwdriver and a hammer to tap off the cap to the fuel tank(standard procedure really). there i removed the assembly and its super simple, no slosh guard, popped out the pump and shoved the new one in, didn tuse the harness adapter or any of the lines they provided, i did use the new sock as mine was black.

rusn good but is loud as hell, and by loud as hell i mean really really annoying, i have no stereo and it sounds like i have a power whine constantly.

I had a walbo in my DOHC and the whine from it was really noticable. Hit the gas though and the engine noise drowned it out

I think the Fiero's return line just dumps back into the tank, it does not go to the pump.

When you installed the pump, did you put the rubber sleeve over the pump to help quiet it down? The Walbro High flow/high pressure pumps spin faster than the GM pumps do and hence they can make more noise. However, with the rubber sleeve on it , in a full tank of gas it shouldn't be that bad. You are correct that the only connection to the pump is the outout line, the return tube is built into the fuel pump/sender assembly.

thanks guys, wish me luck on a smooth install

Ditch those gear clamps and get some real fuel injection clamps.

Definitely DO NOT use the old fuel line, use the new fuel line and cut it to length if you need to.
I re-used mine and was wondering why I was getting crappy fuel pressure to my fuel rail (12-15psi out of 40-42psi) Seems that the short fuel line between the pump and the steel lines exploded.

I have all new fuel lines after the pump and i'm glad I do since any of that old rubber could have also exploded with the 255lph walboro pump.

Also, my pump is pretty damn loud with or without a full tank of gasoline, but my exhaust is still louder =)

ill replace the fuel line, is it 5/16" ?

how many ft?

I'm talking about the 3/8" line from the pump to the pressure line. Its about 2-3 inches long and I can see it in your picture =) Use the one that came with your fuel pump kit and throw the old one away.

that line you are speaking of, is that the same one that busted on you? if it is, is it in hte tank? or can i access it without dropping my tank?

Just remember that some fuel pump manufacturers revers wire their fuel pump.For example,the stock fiero pump would be small prong hot+ and the big prong ground--.On an after market fuel pump it might be,big prong hot+ and the small prong ground--.Be sure ro read the instructions.Use a small piece of high pressure fuel line for your pulsater valve.
