So I aquired a Fuel pressure gauge but its just the gauge itself, I was wondering what fitting I would need for it. Since I am sure TBI lines use different fittings.


Thanks.

 

They do indeed. It's an o-ringed double flare fitting. Same fitting type you usually see on power steering hoses.

They're kinda hard to come by. Usually a salvage yard is the best bet, but I've seen them from time-to-time, at autozone, in the section over by door handles, and window cranks and such.

The best way, in my opinion, to install an external FPR is to use a tubing cutter to cut the steel line (the return line), and then get a piece of high-pressure fuel-injection fuel line (and fuel injection hose clamps), and just use flexible hose to run in and out of the FPR. (usually mount the FPR on the firewall, or somewhere close to where you cut the return line).

I also like to take a tubing flare tool (cheap at harbor freight), and put a slight flare on the ends of the steel line, to help the hose and clamp have something more to 'bite' onto, but it's not really necessary.

Once you're done, check for leaks, and call it a day!

 

This may be helpful. Aeroquip sells a compression fitting to attach to the steel line to assure a good tight seal.
