HPFP fitting weeping

[AceHammer]

Well noticed today that the 17mm nut on the HPFP hardline running into the injector rail is wet with gas. Not enough to really drip but it is definitely weeping.

I had it off while doing my carbon clean, and snugged it up as best I could, but it was real hard to get a wrench on it. How tight do I have to realistically get these fittings. I doubt it's crossthreaded as I spun it on by hand.

Not tight at all - from memory on my old MK6R it was something around 8ft lbs

Hmm perhaps the nipple on the line isn't seated all the way.

Undo it and check threads.

Anyone got any tricks for getting at it, without pulling the manifold again?

crows foot or stubby 17mm

crows foot or stubby 17mm

Lmao been working on this car for 3 years and just learned that a crows foot was a thing. Would have made my life a lot easier. Now that I think about it I doubt that its tight enough. I cranked down pretty hard on the top fitting every time I've removed it and have never had an issue

I have these but they don't utilize the ball bearing lock on my wrench so of course I lost one. Be careful using them. I'd use some tape to keep them on.

Universals might be needed too.

Well that's good to know, cause I was looking into a HPFP

do tell.....

He just did.

Pretty much everyone gets the Autotech pump or internals so that should tell you something.

I might have assumed it was more the price but lets not assume anything

Not many posts under "HPA HPFP failure"

See Jeff had an issue that was fixed as did other post I've seen. I do however remember from my MKV days that Autotech had a high failure rate (yes some to install errors)
