If you're a 95, you should have a service port on the passenger side of the fuel rail. It will be facing upward with a black cap on it. It has a small valve that you need a tool to remove. Once removed, get a -4an to 1/8"npt reducer, you'll probably only find female to male, so you'll also need a female to female 1/8npt coupler. Attach your sender to that. That should be all.

no

home depot dosent have AN fittings
although they do have the schrader valve core removal tool you will need to take out the core of the test port (although a pair of needle nose can do the job)
try Jegs or Summit for your stuff or www.anplumbing.com/

Aeroquip part numbers
-4 to -4 female flare swivel = FCM2914
-4 male AN to Female 1/8 NPT = FCM2721

and BE CAREFUL when you tighten them down, AN fittigns are just finger tight plus 1/4 turn thats it! i sheared the port off my first rail because of tightning issues. (adapter was cracked and leaking i thought it was the conection so i kept tightning)

Aeroquip parts catalog (PDF)
http://www.aeroquip.com/media/performance/A-SPPE-MC001-E-p5-8.pdf
i just call my order in to the local speed shop and they order the parts.

i think anplumbing uses Earls fittings which there catalog is here
