Possible to take fuel fitting off hanger?

Here is a photo of my OLD fuel hardline to fuel hanger pice. There's 2 nuts on each side, 1 a 19mm flare and the other a 14mm flare.

What I'm trying to figure out is if I can remove this hose entirely off the fuel hanger assembley. That is, with this special hose only connected to the fuel hanger, is it possible to unscrew the 19mm off the 14mm that is flared onto the fuel hanger.

I understand to remove the hanger from the gas tank, the hose just needs to be unscrewed from underneath the car with the line pulled up into the car, but I'm actually trying to fix up a fuel hanger I had to pick up from a junk yard to wok on my car. My car came wih a messed up fuel hanger, beyond repairable.

The hanger from the junkyard has its 14mm bolt screwed into the first 19mm in the car, but the rubber hose shown above is cut in half, so the other half is still connected to the fuel hanger feedline. Does that mean I can't use this fuel hanger?

trying to figure out whitch flare nut is supposed to be held in place and which is supposed to turn. I've read the VFAQ on changing the fuel pump and it only goes as far to unscrew the fuel fitting underneath the car and not at the fuel hanger assembley. It says that they are not swivel fittings so does that mean you cant unscrew them?

Here is the fuel hanger assembley from the junkyard:

There's a few threads on here about that particular fitting and it is a serious PITA! When I replaced my sending unit/ hanger I was replacing all the fuel line too. I heard on here how difficult that fitting is to break loose, so I thought I would give it a shot. I could not get it in the car, so I put it on the bench and put a little heat to it. After I let it sit out of the car for about 24 hours for the obvious reason of gas and a torch don't mix well together. To answer your question actually both of them fittings should spin, but from the looks of it your best bet would be to break the 14mm one loose. Hope that helps you out.

thanks for the reply. I've been looking up most of the threads on here and on other forums, getting mixed reviews on which one to turn, although most of the threads suggest holding the 14 and turning the 19, to prevent directly twisting of the hanger's hardline. At the same time, I belive most of the explanations are about taking the hanger out of the car, and the hangers already out getting ready to go in. I have the new fuel line ready for it as soon as I can get this fitting off.

As I was trying to mention above, the VFAQ's page on replacing the fuel pump suggest that the fittings that are on the hanger side of the fuel line are different then the opposite side underneath the car, by not being swivel fittings, even though they appear to be exactly the same.

Luckily I DO have the old line in the first pic to practice on both sides with, so I should be able to figure out the answer to this but it still helps to know beforehand. hopefully I can get the old fittings off since I know how rare they are and I know people need them all the time.

Of coarse it's possible, they are threaded together. Use 2 pairs of flat jaw vice grips if you are having trouble with wrenches. That new sending unit looks to be in awful shape. You will be lucky not to snap that line off.

From my understanding of flare fittings, the 14mm bolt should be able to spin freely, but Im not positive. I'm pretty sure your just not supposed to do it without taking the line underneath first, because the line wouldnt really turn.

Its been hell with these AWD fuel hanger assemblies, hardest to find with the most lines and wires

I really hope the fitting will budge with the hanger in a bench vise, soaked in PB blaster and heated up with a torch. Using flare wrenches of course. Wish me luck everyone I'll post what I find out.

The fitting on the sending unit is brazed to the line so it doesn't spin. The lower fitting on the line to the front of the car does turn. You have to undo the bottom line, than spin the hose off the fitting on the sending unit.

^ Exactly.



Since you are again using the stock lines you'd have been better off leaving that old line hooked up to the car and not cutting it as it's much easier to break the 19 and the 14 loose as opposed to trying to do it while it's off the car. I just did a Walbro 400 swap in my '98 GSX a month ago while the car was on the lift and it was still a pain in the ass to bust them loose, and you have a '95?....good luck with that.

Also as already stated the 14mm on top of the fuel pump assembly does not spin as it's welded to the line and only the 19mm spins. Again good luck getting that off as well while unattached as you're likely to kink that line the 14mm is attached to. I did just that but I had a spare assembly on hand.

That ish is a bish, good luck.

I GOT IT OFF!!!!

Suprisingly enough, the flare wrenchs hardly helped, I only needed the 19mm flare for the fitting on the hanger. I got it off using a torch with PB blaster, having the fittings soaked in PB blaster in the week prior to attempting to unthreading the fittings.

After unscrewing 3 of these fittings I can EASILY say that the 14mm fitting is going to be the one that almost always gets messed up. I had 3 fittings threaded together since the factory and only 1 was messed up before I got to it and now they're practically all messed up. All the 19mm fittings ( the bigger ones) are in almost perfect condition minus aging but the 14mm can easily get messed up by even a flare wrench since it's smaller. I used channel locks on all the 14mm fittings as they would strip way to easily.

and deffinatley confirmed from above^^ that the smaller 14mm fitting attached to the fuel hanger feed hardline, is brazed/welded and does not spin freely so you can only unscrew the 19mm fitting attached to it where as the same 14mm and 19mm fittings from underneath the car both swivel freely, BUT the 14mm fitting underneath the car can still seize up to the hardline from old age / corrosion, the one from my car did and almost looked like it would not spin freely, but I managed to get it off the hardline. The original fuel hanger feed bolt is at the top of the pic, the 2nd one from the top is the orignal fitting that came from underneath the car.
