Yesterday I decided to install a fuel pressure gauge. Matt seems insistent on this and I agree with him. Anyway during the process, it was evident that my lift pump was inop. Dead as a door knob. It amazed me as to how well the truck ran with out it. I mean it ran and started perfect. I don't know how long it was like that, but I had changed my fuel filter around 2 weeks ago and had used it to bleed air from the FM. So at most I was without it for that period of time. I have a LED that tells me the pump is powered up, but now I have a gauge which is real handy. So just because your truck runs OK, don't assume your LP is working. Put a gauge on it!
 
You don't - you wire an led to indicate the LP has power - only a pressure switch or guage will tell you if it's really working, or not
 
Yep... ya never know when you're making your IP workin extra hard or not....

How bout some details of your install? Pictures? 1/4 Barbed T-Brass? How was the condition of your Flt mgr to IP hose? Rough length? Size?

What gauge you go with?

This is the gauge, Matt. It was small and inexpensive, so that is why I used it. I plumbed into the hose going to the T valve with a "t" fitting and 1/8 pipe thread.then ran a copper tube into the cab. The gauge is chrome so I installed it into the lower pop-out plate next to the cubby hole. It has no back light, but it serves my purpose. I do not have a digital camera to show pics. The gauge is a MR. Gasket 1561. I used about 5' of copper tube. The hoses are all new so they are in good shape.
 
mine is plumbed in right b4 ip. one thing I added was a cut-off valve to the cab. just in case of gauge failure while on the road. barbed T and cut-off. noticed a huge difference between stock and Heath's LP under load.

placed cut-off at T

and moved to side, got tired of fiddlin with it way in the back. replaced ops, and lines. This way its easier to replace filter, and clean out periodically. At the same time I pulled intake and moved all wiring above intake.

Bonus was finding 2 wrenches and an allen under the intake.(not including the one I lost months before.)

first pic is another view and second is the new engine:D

Doc, I got that filter manager with the drain port coming out the side too, was that a 94 thing?

I love what you did with the filter manager, great idea.
