6.1 fuel rail tap questions and problem

**SRT8_in_CT** · 04-06-2010, 08:37 PM

I'm hoping to use the fuel rail tap below for nitrous and a fuel pressure gauge sending unit. Seems like it might be a little tall for the fuel line to reach, but not sure. Anyone use this?

I know I have to pull a fuse for the fuel pump and run the car out of gas first. Is there a special tool I need to get to remove the connection from the fuel rail?

It looks like the threaded nipple and plug are sealed with Loctite. I just tried removing the plug and it won't budge, feel like it wants to strip. Any ideas on how to get it out? And if I do get it out, what do I want to use on the threads of the f/p sending unit threads?

Appreciate any help.

Thanks

I used the exact same set up for my f/p on my supercharger set up. That nipple is a son of a gun to get out....but it will come....we used a vise and elbow grease to budge it. We used thread tape on the sending unit for install. Good luck!

I use the same part on my NOS setup. The hose will reach but it will take a little finess.

That nipple I think will work for the gas hose to the solenoid, but when I try getting that damn plug out the allen wrench just starts to slip a little bit and I'd hate to strip that sucker.

Try heating it up.Toaster oven or a mini torch. Dont over heat it because there is a rubber oring in there.. FYI The special tool you are thinking of is a 3/8 fuel disconnect tool..

I figured there was an o-ring in there and was afraid to use heat. Are these things supposed to come with loctite on the nipple and the plug? Seems stupid and wondering if I got a used one. That 3/8 disconnect tool something I can pick up at NAPA or somewhere similar?

Yea autozone,napa all your local parts stores should have the tool you need. No mine came that way new with the locktite

**1FST4DR** · 04-06-2010, 09:34 PM

Yeah bud,That 3/8 fuel disconnect tool is about 6 bucks. And its the locktite screwing with ya,Why they do that I dont know,But some heat wont hurt it.Just remember its not a pizza

Gotcha, don't bite into it after 5 minutes in the toaster oven

Thanks Scott.

Yeah, it was a bitch to get out. I secured the allen wrench in the vise and held the adapter to avoid mangling it up in the vise. Took a little muscle, but it popped loose... I used teflon paste on the threads. I prefer it over the tape...

Good idea, thanks ..

Scott, your tip worked. We whispered a little heat over it with a mini butane torch, and the plug finally let loose. Thank you

Now, the threads for the f/p sender. Teflon paste, tape, red or blue loctite? Looks like it was red loctite on the plug and nipple.

What say the experts?

Thanks for all the advice

Glad it worked for you

Tape or paste will work.Just be careful near the fitting for the N20 as you dont want that to clog with the paste/tape for any reason.

So ya figure I should take that locktited nipple out and re-install it w/ tape or teflon? I figured that sumbitch was in there to stay, as hard as the plug fought me.
