I'm looking for some sort of an adapter or t-fitting to connect a fuel pressure gauge and fuel line to the rail to check my fuel psi when spraying. Can anyone help me out? I've checked local parts and performance stores with no luck.

 

Napa autoparts has them. Male/female/female. That's where I got mine.

 

Is this what you are looking for?

I don't think that's it unless there's another fitting that attaches to it. I also checked with Napa, but they're clueless.

 

Do you have stock or aftermarket rails ?

 

This should be what you are looking for. Basically the same thing as above. Just a different choice.

From looking at the hsw pic, it looks like the hole in the middle of the fitting screws into the fuel rail, where the end of it is capped off with a nut, but can be removed when that end is needed. Correct or not?

Btw, my fuel rails are stock.

 

One of the AN nuts goes on the end of the rail, the NPT (pipe thread) hole is where you mount your FPSS or your gauge sending unit. There will be a core in the rail once you pull the cap off. Just use a tire valve core removal tool to get it out of there.

 

Thanks, but I found one at a performance shop that I forgot about. I tested my system today with odd results: https://ls1tech.com/forums/nitrous-oxide/947711-fuel-pressure-dropped-10-psi-but-still-rich.html
