I installed my fp pressure gauge with the isolator, works fine but we took a bolt off the injection pump and tied the fuel pressure line in there.....is that fine? Will it hurt anything? It's the front bolt on the drivers side.

If your injection pump is like mine, that's the wrong banjo bolt. The front one on mine is a special pressure relief valve that allows fuel to return to the tank. The next one back, the one with the Schrader valve on it, is the supply line from the filter. That line is fed from the bottom of the fuel filter cannister.

On my installation, I put the new banjo bolt (with the 1/8" NPT hole in it) in the bottom of the fuel filter cannister, leaving the Schrader valve in place on the other end.

Here is a link to information on the banjo bolt that I used:

Planning on doing the same on mine.

Tapping the bottom of the filter seems like a PIA

It's not too bad. The only problem is the somewhat limited space to get your arm/hand into position and the fact that you're threading in the banjo bolt by feel, assuming that you approach it from the top. If you remove the air intake hose from the inter-cooler there will be a little more space for your arm but I was able to squeze through there (approaching from the front) with no problem.

If you're left handed, though, it might be more awkward.

I installed mine at the pump Inlet much easyer and just put the schrader valve in the tool box

Yep, me too. Mine is tapped at the VP44 inlet. Good place to tap into, you get to see what is going into the pump. There is only one downside, that spot being so close to the IP you get a lot of pressure pulses that can rattle your guage.

I installed in the bottom of the filter housing...

Its out of the way and I don't have to worry about it.

Same here.

This method also leaves the test port there for testing.

Dealership will want their test port available if you ever take it in.

Still have 50K of warranty left, and I'm 99% sure at least one lift pump will fail during that time.

Not unless you plan to drive that 50K miles in the next year +/-. The warranty seems to be 100K miles or 5 years since the documented in-service date whichever occurs first. Use the link I posted earlier in this thread to determine your truck's in-service date.

The in-service date of my 2001 is July 25, 2000 so even though my truck only has 42K miles the warranty expires on July 25th of this year.

The dealership did replace the lift pump at no charge. Even though they said that the injection pump is within specs I'm still concerned that it was damaged and may fail within the next 6 months to a year. It will be interesting to see if I can convince them to replace the IP under warranty after it has expired. If not, I'll probably just do it myself.

7 years on mine. DC trying to clear the lots for the new 2003's coming in.

I tried that link, haven't gotten a response yet, but I know it is either March 1st, 2002, maybe February 28th, depending on whether they used the signing date, or the picking up and driving off date.
