Engine/Transmission (1994 - 1998) Fuel Pressure Gauge on '95 12v?

[onstottc]

I would like to install a fuel pressure gauge on my '95. I've seen fittings for installing them on newer models, but nothing for mine. CAn someone who has done this give me the details on their installation? Gauge, fittings, lines, etc?

Some have drilled and tapped (1/8" NPT) the banjo bolt on the fuel injection pump for hooking up to a gauge.

Unless you install a PrimeLoc remote fuel filter kit. Then it already has two test ports on it. Mine works great. Do a search in the links for the site. Fairly cheap also.

I did it like bmoeller. The PrimeLoc filter kit is in the way big time if you want to do any work on the injection pump. Nice gadget except for it's location. You also need to use a needle valve in the hole tapped in the banjo fitting. The lift pump on your '95 will beat a gauge or sending unit into submission after a while. So you have to close the needle valve until the gauge barely works. You also need to get a 40 PSI fuel pressure gauge. I use one from Westach. 30 is too low so the gauge gets pegged a lot. 60 is too high because normal operation will be mostly in the first half of the gauge.

Where did you install a gauage prefilter. On the banjo going into the filter?

How nessacary is a fuel pressure gauge on a 12v?

Not very. It's important to very high performance engines but the fuel pressure only needs occasional checking for others. It can indicate a weak overflow valve or liftpump but those only fail maybe once in a 12 valve lifetime.

I've done one on my 98 12 valver.

This takes a different filter than the earlier engines, so what I did wont work on yours. Mine is the cannister type filter, and the mount had pre cast bosses in it made just for this.

All I had to do was drill and tap them.

Genos sales a gage that is mechanical that lets no fuel into the cab..... fuel line goes to a diaphram which has fuel on one side and anti freeze on the other... . only anti freez goes into the cab fuel gage. Seems that I used either a port on top of the fuel filter or a T fitting that was already in my fuel line from the factory... works great!
