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???

Re: Adding a fuel-pressure check port
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.

Re: Adding a fuel-pressure check port
Rather than creating a potential leak problem, you'd be better off
buying or making an adapter you could insert between the line and the rail to check pressure. You don't need a permanent test port.

I would like to study the pressure patterns at idle, during winter, while accelerating and such, so that when a problem occurs, I am somewhat prepared. The problem could be fuel pump, fuel regulator, leaks and such. Moreover, when the car stalls, the problem could or could not be fuel pressure related. My last car, a 1994 Ford Taurus, was running pretty good until 198K miles when it stalled on the road, in 2004. I thought the car is old and would not be worth towing and taking to a mechanic. The car did eventually start but did not have power. I replaced it with my current Jeep. I wish I had studied it's fuel and intake systems; I get a feeling there was a relatively minor problem. |

The problem is getting the fiddly metal bit that is on the rail. I'd probably just splice in a test port with a spare hole for any future pressure gauge. My only concern would be putting excess weight on the quick connector. I've got a setup that does just that and if I'm not careful about the excess weight it can cause a drip in the wintertime.

Ok.. this is what your going to see. ign on -- idealy a few psi from the last shutdown followed by a run up to operating psi start/idle -- basic static pressure running -- basic static pressure wide open -- a couple more psi (depends on the year) shutdown -- a slow but steady build as fuel in the rail expands due to heat. Followed by a return to normal and a very slow decrease Nothing apart from a very sensitive electronic sensor and scope could detect injector firing. About the only things of interest are 1) lower fuel pressure on acceleration - clogged fuel filter - bad pressure regulator (which for your model is in the pump) - worn pump 2) slow decrease in pressure with engine off - leaking fuel system or injector Your probably better off buying a good scantool and learning how to use it.
