Rusted Fuel Pump

[StManTiS]

So I wanted to remove my fuel pump but haven't been able to get the fitting to come off no matter how hard I try or how much WD40 I use. I've heard of cutting the hard line, but then what? And where should it be cut?

 

[tsi4g63dohc]

did you put the block of wood on one side of the wrench ? Let some type of wd40 or something sitting on it over night , keep soaking it, mine were so badly stuck it kinked the line on top the sending unit and under the car, I ended up ordereing the tank to rail kit from stm , and check my pictures, that's how I fixed my sending unti from kinkin the top line

I cut mine. Used some fuel hose I had from work, and it doesnt leak. I also cut the other end of the fitting off as well.

 

[tsi4g63dohc]

oh yeah check vfaq.com

 

[StManTiS]

Well I have tried letting WD soaked and have put so much force into it that the hard line is now twisted ><

I'll give it another try with the wooden bock idea, but i dunno if that'll do anything...its a real rusted PoS

Well I broke an inch thick piece of wood, but putting a wrench under it worked...so now I got my pump out and its a mess. Like a seven year installed a walbro ><

 

[tsi4g63dohc]

you twisted what line ? how badly twisted?

 

[StManTiS]

the metal one...its not terrible (i think)

If you do want a new line, they are surprisingly cheap to get from the dealer. I bought the clutch hard line for my 1g for $11 plus shipping.

 

[StManTiS]

Could a badly wired or poorly grounded fuel pump cause a car to run very lean, like stalling out lean? Could a bad fuel filter?

The hard lines on the fuel pump assembly are welded to it. If you bent/twist/break them you either replace the assembly or custom rig something. The assembly is $400+ from the dealer.

just check out the stm kit, it's pricey for a line and fittings but it worked out great

a bad bad fuel filter can. So can a bad fuel pump, FPR. A lot of things, I always start with the cheap/obvious when I troubleshoot. I like to work my way up to the headaches rather than start one for no reason. I'd say a bad ground/wiring the pump wouldn't work at all. Well if its not badly twisted you can just test your luck... start it up stuff a shop towels under the fitting, e-brake and check. If it does not leak and you don't to spend the money on peace of mind then always be weary of that possible fuel leak.

 

[StManTiS]

The pump is a Walbro GS341...I have replaced the FPR already.

But which walbro is that and do I need something special for it to work?

 

[Jerkychew]

That is a walbro255 and no you dont need any special work done to it as long as it works.

Whoops, I didn't know the fuel line was that involved. OP made it sound like they were banjo bolted to the fuel pump, but I guess that part is on the other end.

A flare nut wrench is the proper tool to use for this job. It "grasps" the fitting on the tubing from all sides as opposed to just two sides on a regular wrench.

For the price of a flare nut wrench, its a good investment.

The only banjo fitting is on the top of the fuel filter up front. Read the VFAQ for more on swapping the pump on a 1G AWD. Walbro 1G fuel pump kit install

I had to cut the fitting off on the sender, then i cut the fuel line and use hose clamps and fuel line to put it all back together. It worked out fine. if you were looking to mod the car heavily i would suggest ordering the STM kit it is relativity inexpensive and is good Quality.
