Isspro drive pressure guage

[rulonjj]

I bought a electronic isspro drive pressure guage for my truck. When I was reading through the instructions it said to not allow the sender unit to reach a temperature above 275 F. how would I plumb that to work. Any ideas or suggestions would be appreciated.

Copper or stainless line a couple feet away from the manifolds or wherever you are tapping into.

I use about 12" of 1/4" aluminum tubing with no problems. Understand that the hot gases will not travel down the tube (only a pressure wave) unless you have a leak, so make sure the seal is good on the sensor side.

I used AN fittings, flare tool, and tube from Summit Racing. You can bend aluminum by hand.

Is anyone using filters in there set up?

The reading "pulses" quite a bit. It really does need a mechanical filtering of some kind. It would probably assist in increasing gauge life and making the readings easier to read.

I never tried this, but one thought would be using a larger tube dia, with about 1" worth of steel wool loosely stuffed in the tube.

What about a dessicant filter? The aluminum isn't melting?

That's a good idea. I will try it and see how it is.

you guys think a guage for drive pressures is required all the time or more just for setting up?

 

[rulonjj]

I'll prolly leave mine in since I have it. But then I always like to tinker and change stuff.

Just for setting up.

Mine has a section of rubber hose (few feet of it tucked into the frame) rail that utilizes a lawn mower fuel filter to keep the goo puck out of my gauge. It's a pretty simple setup and when it gets clogged, it's an easy fix.
Mark Broviak whipped this up for me when I was at Danville Performance in May.

mines never clogged on me nor do i have any soot in my gauge that i can see. I used the small 1/8in copper line all the way to my overhead console. I hear that some rubber line in there somwhere reduces noise and a bit of flutter, which i need to try.I made a cooling coil right before it goes in the cab but i can grab the line pretty close to the motor and its only warm, prolly from radient heat. As said, make sure you dont have leaks.

if you use a needle valve(inline, and almost closed all the way) near the firewall, or closer to the guage, it will cut down on the pulses and the bouncing of the guage needle tremendously.
