Adding a fuel-pressure check port
 

I occasionally want to measure fuel pressure on my Jeep WJ 2004 4.0L
I6. I am looking at installing a Schrader valve - the Jeep deosn't
seem to have one. Can anyone provide suggestions on where to put a
schrader valve and how? I was thinking of cutting the plastic hose
close to where the fuel enters the fuel rail, inserting a 1/8" NPT
brass T with a Schrader valve in the middle, and clamping with two
screw-clamps. Any safety issues here? Is there a better long-term or
safer solution?

Also, occasionally, I would like to be able to check pressure while
accelerating etc. Is it worth installing an electrical sending unit so
I can connect a couple of cables and a gauge and stick them to the
windshied when testing?

Thank you.

Re: Adding a fuel-pressure check port
 

You could install the valve like you mention. They make solid
track/band worm clamps for the higher pressure lines something like the
ones with the slots for threads.

I don't really see the need though. Usually when a Jeep fuel pump up
and quits, it up and quits. Unless you are having issues???

What's a band worm clamp ? Is that what we call a Jubillee clip over here ?

Re: Adding a fuel-pressure check port
 

The normal 'hose clamps' that screw along a slotted track are called
worm clamps. They make them for higher pressure applications with a
solid band stamped with threads.

I either use one of those or I double the old style ones.
