Whenever possible, I like simple and easy.
I'm looking to get a fuel pressure gauge--I've heard/read that it is a necessity. Problem is, I'm not a very good mechanic. While browsing "genos garage" yesterday I came upon Item Number : LT_FFCPP.
It is a replacement cap for the stock/generic cap, but it has a built in tapped plug that the site cames allows easy connection of a fuel pressure monitoring hose ((quote: The fitting will accept a 1/8” NPT pressure sending unit, perfect for those who wish to monitor fuel pressure. Allows pre-filter fuel pressure monitoring. end quote)) Looks simple enough...a little price @ $59 however. Anybody seen or have comments about the cap? Here's full item description:

Since the fuel filter assembly revision by Dodge in model year 2000, we have been looking for a location to give owners easy access to the fuel system, thus enabling you to monitor fuel pressure. The original answer was replacement of a banjo bolt with a tapped banjo bolt.

In lieu of replacing banjo bolts, it’s also possible to screw a fuel hose into the ‘00-‘02 engine’s Schrader valve, but ‘00 and newer trucks don’t have a Schrader valve, so we developed a fuel cap for the fuel filter assembly that replaces the assembly’s plastic cap.

The polished metal cap has a 19mm (3/4”) hex-head for easy removal with metric or SAE tools. The center of the hex-head is drilled, tapped and plugged. The fitting will accept a 1/8” NPT pressure sending unit, perfect for those who wish to monitor fuel pressure.

Allows pre-filter fuel pressure monitoring.

 

The last sentence ruined it. You want to measure the pressure after the filter so you know what kind of pressure the vp44 is seeing, and so you can tell when the fuel filter is starting to clog. There are options as simple as a t fitting or what they call tapped banjo bolts.

I'd recommend going ahead and doing a line kit at the same time as you set up the fp gauge because once you get the gauge on there you're going to realize the stock pump needs help =P
