Engine/Transmission (1998.5 - 2002) Fuel pressure sensor location

[Sandmancw]

I have my gauge installed, just need to hook up the sensor. I bought the fuel pressure line from Geno's that screws on the Schrader check valve. The recommendation is to attach the sensor to the engine so they vibrate together. My question is where and how did anyone locate the sensor on the engine. I do not have a machine shop to make special parts, also not that mechanically inclined, so simplicity is of the essence.

This is for my 2001. 5.

Any help would be appreciated.

Happy New Year.

The recommendation is to attach the sensor to the engine so they vibrate together.

Who told you that? The sensor needs to be attached so that it is completely isolated from the engine vibration and 'water hammer' effect of the injection pump. I prefer to run a rubber grease hose fitting from the bottom of the fuel filter (leaving your Schrader valves intact) and mounting the sensor off of the firewall. Putting the sensor on the engine will surely lead to failures.

The information that Geno's sent along with the Westach sending unit.

Westach Fuel Pressure Sending Unit Discussion states:

"We would suggest a mounting location like the one in the photo (sending unit vertical; flexible line from a R. L. Torrestal tapped banjo bolt to the sending unit:sending and tapped location are both on the engine and rock/vibrate together) rather than mounting the sending unit away from the engine on the firewall or fender area. "

In this case I am using the fuel pressure line. The picture shows the senor attached to the top of the throttle lever cover by a fabricated bracket. On my truck the throttle lever cover is plastic and the screw that holds it on is plastic and doesn't appear to thighten down(keeps turning). Maybe I am in the wrong location but do not think so.

I personally used one of Ray T's tapped banjo bolts on the bottom of the fuel filter cannister and ran a 3' section of SS fuel line(picked it up from Summitt Racing, it came with the proper ends attached cant remember if it was 3 or 4 an size) to a needle valve with my sender attached to the other side of the needle valve and then zip tied it up by the master cylinder. Been there for 40k with no problems. By using the bottom of the fuel filter it still leaves the stock schrader valves (though I did drill them out to the same size as Ray T's banjos) for testing purposes. My original setup used the schrader at the lift pump and the dealer was going to charge me 90. 00 to r&r it when they replaced my lift pump under warranty. Ran up there and took it off for them in the parking lot for 90. 00 took me all of 10 minutes. When I got my truck back I moved it to the bottom of the fuel filter cannister to avoid that issue in the future.

FO PSI SENSOR MOUNTING

Here is where and how I mounted mine almost two years ago, the sensor has been perfect.

It is mounted to the dipstick tube bracket(there are three holes already in the bracket, no drilling needed), using wire strap with eyelet. I wrapped the sensor with rubber stripping and foam to help with any vibration. I used aeroquip hose and fittings, needle valve and threaded banjo at the VP44 inlet.

If you need p/n's let me know.

BarryG has a good method for a reliable installation. I too use Ray T's tapped banjo bolts for the installation. The use of the SS lines and needle valve is an excellent method for plumbing to the sender and dampening of the 'water-hammer' effect. I also mounted my sender on a custom bracket which is mounted to the master cylinder (firewall). Mine has been going strong for 2-1/2 years and has already flagged two failing lift pumps.

. . . sending and tapped location are both on the engine and rock/vibrate together) rather than mounting the sending unit away from the engine on the firewall or fender area. "

I disagree with this statement unless you take extra precautions to insulate the sender as DShuart did. I think that the intent was to discourage applications in which the engine movement causes the hose to pull on the sender. Of course, you must allow for this movement when using the remote sender.
