The brass thingee is the adapter you will need to safely install a fuel pressure gauge in your dash (mechanical gauge). The gauge will read raw fuel pressure upstream of the TBI regulator, which is what you really want. if your fuel pump starts south of Terra Del Fuego, you will know it instantly. You might have time to get to a repair shop before it completely craters. I will run copper tubing to the diesel isolator (transducer) mounted somewhere in the engine compartment, and run tiny little plastic tubing from the diesel isolator (transducer), through the firewall, and to the gauge in the dash. No fuel inside the coach, and no way to get there.

More pictures to come as I finish the installation.

These are the other components you will need. I bought these off ebay for $25, which was a serious bargain for $200 worth of parts. As soon as the installation is finished, I will post more pics. FYI, the silver thingee is the diesel isolator ($80 new) and the other is a very nice fuel pressure gauge (illuminated of course) that sells new for $120.

I finally got The fuel pressure gauge hooked up except for the instrument light wiring. Pics tomorrow. I am just too tired right now to hassle with Photobucket. I filled the isolator and the 1/8" line with 3 in 1 oil. I used an insulin syringe for the task.

Guess what? Fuel pressure is 3 psi. Time to drop the tank. I feel better about the job since I know for a fact the pump is history. All vehicles should come with a fuel pressure gauge, especially now that the cost of replacing the pump can be in excess of $1500.

Good luck and happy travels,

Jim and Boo
