Im in the process of installing a Autometer elec. fuel pressure gauge.
The best place looks like a fitting right before the fuel enters the fuel injector rails. However, finding the fittings for this connection are a PITA here in the bay area (from large metric, to standard, to an Earls 'AN' fitting).

Since the pump is in the tank and the pressure is controled by a regulator which allows a certain amount of fuel to return back to the tank---can i just install the fuel pressure sender in line right after the tank (rubber hose--splice a 'T' fitting in)????? would the fuel filter have a neg. effect on my pressure?

if so, i'll install it near the rails, but who the hell has stuff that goes from huge metric to standard?? i tried american streetrod off sunrise a few weeks ago and they said no chance of earls or aeroquip making something like it.

Is there a place where you could cut the hard line and install Tee fitting with compression fittings? I did this years ago on an EFI Mustang. In fact, I also used compression fittings on my current mustang to splice the fuel line. At the time, no one had those spring lock tools. Seven years later, they're still there.

As far as installig it before the fuel filter, it wouldn't tell you how much fuel pressure your engine was getting, but it would sure tell you when you need to replace your fuel filter.

Fuel pressure gauges are meant to be a PITA. To many guys not thinking and running a mechanical gauge inside the cab. If you have EFI why do you need a gauge at all? They do make the adapters to hook to your fuel rail so that you can hook up a temperary gauge for dianogansic work. Flag down a Snap On,Mac truck, he will have one .

i guess i could cut a hard line, flare it, then splice in the necessary adapter, but that earl's stuff runs $$$$$. I need the elec. pressure gauge because my truck has been giving me fuel delivery problems on a very erratic basis.

Sounds like a bad power problem. I would wire in a small lite to the fuel pump power. Tap in right before the tank and run it to a small LED or light that's in the cab it sure sounds like you loosing power at some point to the pump.

yup..have that in the plan as well. but when it wouldnt start up, i bypassed the wiring, checked the pump, and it was all good. I already replaced the fuel filter, but may have a faulty fuel pressure regulator. I also checked into one of the kits from snap on, mac, etc...and they are way more than my gauge--but a lot easier to use.

What's wrong with doing this?? risk gas/gas fumes getting in the cab??

Having the line pop off and spray gas out at 40psi comes to mind. and It's illegal in most states

I had a good buddy burn the shit out of his girl friends legs with hot oil off of a broken oil line to his gauge. <IMG SRC="smilies/smokin.gif" border="0"> <IMG SRC="smilies/smokin.gif" border="0"> <IMG SRC="smilies/smokin.gif" border="0">
