Fuel system install question
 

Hey guys,

I'm working on installing my KG Parts fuel system and I have a couple quick questions I haven't been able to find the exact answer to. I'm screwing the NPT->AN fittings into the fuel rails. I am using plumber's tape to seal the threads. Now, my questions are...

When I screw the NPT->AN fittings into the fuel rails, how tight should I screw it in there? Should it be tight at all or should it be loose, allowing the plumber's tape to seal it?

Thanks!

Use your calibrated elbow but it needs to be tight. If not, when under pressure, you'll have a slow leak.

I installed that kit and had to pull it out twice because I developed leaks. Nothing wrong with the kit, I just didn't have the fittings tight enough or I had to reposition the directional fittings to get my lines routed correctly.

My advice is to dry fit everything, figure out which way you're going to route your lines and which direction your fittings should be facing. You're gonna have to use some judgement when tightening everything up because some things will have to be looser than you would want so they face the right way. It's more of an art than a science.

Another point to consider. I would leave the solenoid rack off if you still have it, I see the single turbo in your avatar so you probably don't. Dry the top of the housings because you're going to spill some gas on them. Make sure they're really dry!! Once you get everything back together and the lines primed, check the cutouts on the housings for any slow leaks or major leaks. If no then you're good to move to the next step. Run your car for a while but don't go driving it. Go back and check the lines again for leaks, look mainly at the top of the housings again. If you're leaking fuel, over time it will build up and may start an engine fire. If you're still dry and there's nothing leaking on the ground, you probably got it right. I would still be cautious for a while and check back in a day or two just to make sure.

The reason I say this is because I had a very slight leak that I didn't detect until a day later when I was looking for something else. Could have been a big problem.

If you need help getting your Computer setup, I can give you some tips on that too.
