1G Fuel Sending Unit replacement options?

[1Gab Laser]

The shop is telling me I have a gas leak, which I know is a load of crap because I've had the car running for a year now, and other than driving it to the shop last Tuesday, every time it's run it's just sat idle. I'd let it idle for a while just to lubricate all the seals and gaskets. There have NEVER been any puddles under the car. so I don't see how I supposedly have a gas leak...

But anyways...

They won't inspect it till it's fixed, and they have to fix it because my 10 day grace period on my registration is over, so I can't drive it home to do it here.

They called Chrysler and they said the part was discontinued. They didn't bother calling Mitsubishi, but I did, and they said they can't do anything without the part number. I was like "Well if they give me a part number at Chrysler, it wont be a Mitsubishi number?". The guy told me it would be a Mitsubishi part... so then wouldn't it be discontinued from Mitsu anyways?

Back to the topic again...

I'm making a junkyard run tomorrow to get a fender for my friend's Subaru, and the same yard that has his car has a pump and sending unit from a 92 Eclipse, and I'm pretty sure it's already off and in storage because I was there last week and didn't see any 1g's in the yard.

On car-part.com, there's only 1 option for the fuel pump on a 1991 Laser. It's the same as the one on an Eclipse before 1/31/1991. The 1991 Eclipse has a whole bunch of options. 1991 after 2/1/91 goes through 1992. Where this one they have is off a 1992 would it work? I'm wondering if maybe its just got a higher flow rating or something?

While I'm at it, is the one from a 1993 Eclipse with a 4G37 the same? I have a junk 93 here, I just don't know if that'd be the same. If it is, would it be worth the effort of dropping the tank and pulling out the pump/sender? Or would I be better off to just pay $40 or whatever and get one from the yard? Just wondering how much of a job it is.

i got the same problem right now junkyard just charged me 200 bucks for a sending unit that was almost worse than mine....and they said theres only like 2 in the country brand new and theyre in michigan and wanted 600 bucks for it

$200?! They should throw in the gas tank for that much

you can get to the sending unit from the left side of the trunk. Pull up the carpet that covers the spare tire and there should be a plastic plate of the left, unscrew it and there is the access plate for the sending unit and pump.

Just get the car to your house and fix it there. It's probably the hard line going into the sender that's leaking. It's a pretty easy fix and shouldn't cost you any more than a couple of bucks. The shop will replace the entire unit if they can find one and probably charge you triple for the part plus an exaggerated labor charge to put it in. As far as I know all the AWD sending units are the same from 90-94 but I'm not sure about the N/T or FWD units.

AWD and FWD are not the same, like coop795 said it's under the spare tire in the hatch for AWD. On FWD it's underneath the car on the front of the gas tank.

Just to give you a heads up, those rusty screws that hold on the plate for the FLSU are not gonna come off very easy, try using PB Blast before you attempt to unscrew them, even then there's a good chance they're gonna strip and then you'll have to drill the screws out unfortunately. If you do have to drill them out, DRILL SLOW you don't wanna make sparks under there, or if you really wanna be safe, empty the tank first.

if you really wanna be safe, empty the tank first.

That's the worst case unless you then fill the tank with water or something else non-flamable. It's gas fumes that ignite and an empty tank is full of them where a tank full of gas is pretty safe.

 

[Trav83]

Ok you're probably right on that, but isn't he most likely gonna have to empty it anyway so it doesn't pour out when he removes the FLSU? Unless he goes to a junkyard, then it's gonna be empty anyway.

I haven't swapped the pump assembly on a FWD. Which is he changing, the pump or the sender, since they are two different things on a 1G FWD unlike the 1G AWD.

I'm assuming the real problem is with the fuel pump. Is there enough space to drill, if needed, without dropping the whole tank?

 

[Trav83]

Well looking at the previous posts, I would assume he's talking about the sending unit. I really don't think you would have to drop the tank out, I've been down there before and it's pretty easy to get to it.

You may never find a sender in a junk yard. The gas tank is one of the first things they remove and get rid of. Try one of our fine Vendors, such as Mitsubishi Graveyard.

At our junkyard they keep the gas tanks on, but they punch a hole in it to drain the gasoline. I do agree with you however that he should check out Mitsubishi Graveyard, as there is a greater chance they would have it.
