Hey guys, I'm trying to install my walbro now... took two guys but we broke the 14mm/19mm fittings apart. However, while trying to unscrew the line, I can't get it all the way off. It twists so much and then it's just like a knot of hose. How have you guys gotten your fuel lines all the way apart?? (the 2GNT wiki doesn't mention anything about the hose not being able to rotate enough)

I'm running into problems everywhere trying to turbo this car LOL.
 
to clarify:

the 19mm fitting connected to the fuel hose - is it supposed to let the fuel hose spin freely inside of it, or is it supposed to be solidly connected? If it was supposed to be able to spin, then I could just unscrew the fittings and pull the fuel pump out. But mine won't spin without twisting the fuel hose with it... and it just keeps twisting so much I'm afraid either the hose with tear or it just won't be able to physically twist any more between there and the hard line connection under the car.

This is super frustrating, please let me know if the fitting should be able to spin without twisting up the hose or if there is any special technique.
 
I don't know if this helps you now but I bathe DSM fuel
line fittings in JB-80, Knocker-Loose or your favorite
penetrating oil...every night for 2 or 3 nights before I
loosen them.

Doing so will allow the fittings to break loose and they will spin on the line.

To answer your question: If your fitting is not spinning, it is rusted to the line.

I'm pretty sure on the 2g's you have to unscrew it from underneath the car, and then you can take the fuel pump out. I did the same on my car and ended up twisting the line, and about a week later, once it got under any kind of real pressure, the line snapped.
 
alright, so try getting it off from under the car too? Maybe I should just replace that line then since I already twisted mine up a bit. I'm just afraid of snapping the hard lines, those fittings are so tight.
 
Actually, if I remember correctly, I'm pretty sure that fitting is NOT supposed to spin. I remember having to go downstream a little bit, where the rubber hose meets the hard line... if you disconnect the rubber hose there, you'll be able to pull the fuel pump assembly with no problem.
 
You could use a pipe cutter and then double flare the line. Use some an fittings. If you go that route i would buy some braided hose to run to your engine compartment to help fuel flow even more. Just be sure to upgrade the size of course:thumb:
Edit : yea, ive seen some break loose easy, and some not. People do say they are brazed, but i doubt it most likely its corrosion or something

Yeah downstream as in underneath the car, not in the back seat.
 
The hard feed line on the 95's don't unscrew right at the bracket, you have to go underneath the car to get to them undone. The 96-99 you can unscrew right at the top of the fuel pump bracket.
 
You guys have your upstream and downstream backwards.

Upstream is always towards the source. Your fuel pump is upstream from your inline fuel filter. The fuel filter is downstream from the fuel pump.
 
Thanks Paul and Mike and whoever else had the correct answer.

Just to confirm - Yes, undoing the fittings where the hose meets the hard line under the car was the way to go. 14mm fitting spun free on the hard line, then once the rubber line was detached I unscrewed the fittings in the car and slid the fuel pump assembly right out. Lol that was harder than swapping out the pumps. And I didn't have to modify my bracket at all like the 2GNT wiki, mine fit nice and snug through the original screw hole.
 
good job on gettin it done OP

Thanks man, it feels good. I got it started up yesterday. I've done all the work myself throughout the week when I wasn't busy with class or homework. It sucks now though because it's my spring break finally - had to come home for a doctor's appointment, and I didn't want to trust the car on a 300 mile road trip the day I finished the turbo install LOL - so now I have to go a week without driving it :cry:
