Easy Drive pressure guage & sensor install

18194 45
This is where I tapped in , took 45 minutes and a small test drive and it was all done . also a picture of the pillar and console mount . total cost for fittings , brake line and a cup of coffee was under $10.00

For added heat dissipation but I doubt its really necessary , the sensor cannot exceed 250* Fahrenheit . Thank you all for the input . I have gotten a lot out of this truck site just wanted to give a little back

I kind of figured that. I guess Cummins was thinking about the heat when they mounted their pressure sensor on the radiator hose neck as well.
yessir, nothing like a big ole' cooling fin right by the fan to help that out.

Exactly what I did, I couldn't find the right tee fitting so I got a reducing coupling and a 90 can't see it tho behind my manifold..

Yes I bought it from isspro , they have a huge variety but most vendors just list the basic ones , the port is a pressure sensor of some sort don't know exactly what it does

Ok this might be a really stupid question but could I just tap into one of the egr cooler plates?
Yes you could but you need enough line length for it to cool down enough as to not bugger the sensor up

Yep, that is how I did mine as well.

This is the best way IMHO. definantly one of the cleanest.

I used all stainless with swagelok fittings.

Nice job!

I do believe that is the drive pressure sender that is used to monitor DP for the exhaust brake.

I bought a liquid filled gauge for 11.95 its available at any tractor parts, napa, hydraulic store etc.

0-100psi.

I just tapped into the plate with a 1/8 npt then went to a 1/4 brake line coiled then copper like to a oil psi gauge into the truck.

So you took the Factory sender out of the T-stat fitting? The one at the end of the stainless tubing from the exhaust manifold? Did you plug the hole or leave it open?

I would put that factory sender back in. I can't think of any reason to take it out.

Yes you absolutly do , just tie into it like I did . It still must function as its suppose to

I didn't realize that the 6.7L added a factory drive pressure sensor. I'll have to add a reference in the instructions for the ISSPRO Exhaust Backpressure Gauge.
