Had a leak in the high pressure line.
Swapped it out for a new one - getting to thread it to the gear box was a b**** as I expected but got it done.
Had to remove the low pressure return fitting from the gear box to be able to correctly align and thread the high pressure line.
An hour's worth of attempting to reinstall the low pressure fitting has been unsuccessful.
It feels like I am able to barely engage the threads between the low pressure fitting and the gearbox but can't make it stick when applying a wrench.
Any tips? It seems that more downward pressure on the nut would help it engage but difficult to apply.
Tips, thoughts, suggestions?

 

Those are tough. I assume you took out the airbox. If you haven't, definitely do that and it will make things easier. Even with the airbox out, it can be difficult to get those started into the gearbox.. May be worth trying from underneath tog et a different angle on the start. Once I get them started, I use a crows foot wrench to get them all the way tightened down.

 

I did remove the airbox and pulled the radiator hose out of the way. I only removed the low pressure line so that I could thread the high pressure line; the two metal tubes were just too close to one another. Are you suggesting to try to thread the fitting from a position underneath the vehicle?

 

I had this situation, and the thread on the lines is very soft and prone to cross thread

I took a very fine triangular file and was able to restore the thread

This is can be tricky, but I have done it quite a few times before, good light and high magnification helps

 

I was able to thread the high pressure fitting but now can't seem to get the original low pressure fitting to thread. It seems like I need a way to put downward pressure on the fitting while turning it to help it thread. I've tried using a screwdriver but didn't work. Any tips or just keep trying and be patient?

 

Have you managed it yet? If not, have you tightened down your high pressure fitting? If so, loosen it so the line can move about a little.

Are the high and low lines touching anywhere?

If the high pressure line was easy enough to thread in for you, remove it again and see if you can get the low to thread alone, after checking it's threads. If the low just screws in, it's just a matter of keep trying or working out exactly what is stopping it from going in.

 

Won't have time to take another swing at it until this weekend or next. High pressure fitting is seated but loose. Lines are close but not touching. I don't want to remove the high pressure line to seat the low pressure line. It was a beast also and I originally removed the low pressure line to fit the high pressure. Part of the problem is there is very little wiggle room but appears the biggest challenge is applying downward pressure on the fitting while turning it to help the threads grab one another.

 

Mine was nothing but a major pain in the kiester. I fiddled with that until I start creating new cuss words...then when you least expect it...it seats and the nut spins on by hand (fingers) a couple of three turns....

 

Been there, done that. Yep those line suck to get back on.

 

I has same issues with mine. I just kept trying and finally got it. I do tend to do these things with my eye close and go by feel for some unknown reason it helps me. Sorry it's all I can add.

 

Thanks everyone. Sounds like persistence is the key. I'll get after it next weekend again. I have all day. I should be able to get that one fitting installed in that amount of time.

 

Haha same here! Apparently I can't see straight but my fingers can feel straight. I fought one of those connections for two hours and my buddy walked over and spun it in first try 🤔. The first thread or two were a little worn down and wouldn't catch, for me anyways.

 

The saga continues. I bought a new low pressure return hose with a fresh fitting thinking that might be the cause. Nope. Same result. I can feel the threads catch with my fingers (increased resistance) but then it spins off when attempting to turn easily with a wrench.

 

It should say in the FSM, this job is a *****

The first time I did it, I had serious trouble and wrecked the thread

As I mentioned, using tiny files, I corrected it, under bright light and magnification

When doing the job subsequently, I noticed there is a side load exerted on the hose as you try to screw it in

Pretty sure I had to have one line very loose and jiggle the other while keeping it straight and getting the fastener hand started

It must hand thread, the thread is like butter

When I got my corrected thread straight back in, it was like a miracle, done it a couple of times now, keep it straight and hand thread while jiggling

 

Thanks awg. I've done all the things you recommend and still can't get it to bite. Unfortunately at this point my patience and time has run out and I'm going to pay someone for their time and patience to fix it. Such a simple job too!
