How do you depressurize the fuel system when remote-testing?
 

So, I've read on the forum to get some longer feed and return hoses, prime the pump with the rails uninstalled and "remote," and check for leaks.

However, what's the proper method of depressurizing the system this way? I can't exactly start the car and pull the relay, since the rails aren't installed. Or, is the system not exactly fully pressurized, and gently pulling the hoses is perfectly okay?

you could try just opening the fuel fill cap. maybe that would let out some of the pressure.
good luck

Hell, even if the system is fully pressurized and you open a line, just hold a rag around the fitting when you take it off and youll be fine. It only gonna spurt once. I dont know where the test port is on these cars, but their might be a little schrader valve somewhere.

Yup, just remove the fuel cap and have some rags handy. Won't be a big deal.

P.S. No open flames or cigs in the area ;)

Darn....I was planning on lighting a cigar to celebrate a non-leaking system. Or, a cigarette to help me relax when I'm frustrated at a leaking one.

Thanks, guys.

Or drop lights, either:

That thread would be more informative with some pics ;)

Good warning though, you never can be too careful.....enough FDs have expired due to fire.....

Yeah, and watch out for those propane heaters in northern states! They're like an afterburner. Luckily nothing caught fire when pulling my motor.
