Tommorrow I will be putting gauges in my 12V mounted to a pillar pod. I'll be installing Di-procol EGT, 0-60 Boost, and 0-100 Fuel Pressure, I know how to do the EGT and Boost as far as what to drill and where, but I have never even seen a fuel pressure gauge been installed. I've read on here about using a needle valve and a piece of stainless steel hose straight to the gauge, but what size needle valve and what size/length of the stainless line and what kind of sealant as well? Where can I get them? I looked at the needle valves at work and the specialists told me they wouldn't work for what I was going for??? Also how did everyone wire the gauges up, when I went with a friend to Randy Hord and got his dual gauges installed however Randy wired them screwed up his turn signals, I really don't want that to happen. lol. Thanks for all the help guys!

 

B.T.T Can anyone atleast just tell me what size needle valve and hose? Thanks!

 

just wondering? why are you putting a fuel pressure gauge on a 12v? only the 24v really need them good old p7100 pump never dies. I'd do tranny or diff, or a after and pre turbo pyro first.

 

Several people have reccomended one to help in diagnosing problems due to low fuel pressure, also I feel it's better safe than sorry. I'm also partial to tripple gauge pods if nothing else... lol. But in all seriousness I felt like it was a good idea.

 

Fuel Pressure gauges are important on 12v trucks too, especially at higher HP. It is not done to monitor fuel pressure in a pump saving sort of way , it is done for performance , filters get plugged , lift pumps do fail , and overflow valves also fail , a FP gauge alerts you to this immediatly.
