Can say enough about this stuff.
Greg Brown recommended it.
Had a leak at the ball/cup union of the dampener to the rail. To visual it was smoothed out with 1200 grit paper. I did note an irregularity on both mating surfaces. After the polishing still with leak.

In comes Greg's recommendation.

Not a drop !

Thought I'd share.

So if the 574 works, then the other stuff must be unbelievable....

Rob,
It actually puts gas into the fuel tank.
Leak abatement in reverse !

Excellent!!!

On a more descriptive note, this agent cures very fast.
I had applied it to the union of the FPR and rail and the union of the FPR to the cooler. Took me 2 - 3 mins to secure the FPR/rail union and the stuff on the mating surface of the FPR/cooler face was already rubbery.
Will do well in other leak prone areas such as tensioner bolt that enters the galley, and some water pump bolts. This, provided that the threads are clean and dry.

What sort of price are you paying for Loctite 574?

I just had a look for local (West Oz) suppliers, and they want $50 - $70 for 50 ml! (~1.7 US fluid ounces)

I paid $32.00 about four years ago, from Bob Whyms in Sydney .. so sounds about right. I couldn't find anyone here in Tas who stocked it.

I find Blue Universal Hylomar also excellent for this type of joint.

Here Amazon had it for 36 $ for 50 ml tube. My local Fastenal shop had it for about the same price, but he didn't have it on the shelf. Didn't want to wait.

From foggy memory, 574 has a shelf life that's pretty short. IIRC it's something in the few-days range after it's opened, and 90 days from date of manufacture. I'm sure you can confirm with Loctite website info. Anyway, retailers are loathe to stock a lot of it for that reason. It may also explain the high price if Loctite has to buy back aging inventory on shelves. For some things, it's the perfect solution, cost not a factor..

I used 2 year old loctie 574 on my head galley plugs and it sealed up just fine. I evacuate all the air out of it and close the lid when done.

Just got a bottle. How much should I put on the fitting for the high pressure line that goes across the front.

Don't want any excess going in the fuel rail.

MainePorsche

I just put a 'dab' on the ball side of the flange joint. Make sure it is circumferential for the seal.
Has to be clean first.
It does cure quickly.

And...
If you have to disconnect and reset, clean it out well and add it again - it will have already cured.

New fuel line installed with 574.

I read through the data sheet, it shows full cure time as 24 hrs. Has everyone else waited this long on the fuel lines?

It's a sunny day, itching to drive. Should I wait the full 24?
