Is diprocol the only company that makes rail pressure gauges, and were is the best place to get one?

 

Nope, quad makes one for about half the money. Its a digital gauge. You can get one from the DTR shop!

 

thanks for the response, is one better than the other?

 

I just installed a quadzilla rail pressure/fuel pressure gauge. It works perfectly. I wish I could read both parameters at once, though, ...but for the money, Im happy. I paid $160 shipped, used.

You can get them as cheap as $190 shipped, new,... though.

 

I dont think one is better than the other but I like the analog guages better. I have the digital tst rail guage and the dipircol analog and it is just much easier to see what your rp is doin with a dial. Doesnt mean it is better than a digital guage, just suites me better.

 

SPA Technique has a nice one. I ran it on my '03. It has rail pressure and another pressure reading that you can use for fuel, oil, or drive pressure. Just depends on what you want. It has programmable alarms as well. You can even wire in a separate audible or visible alarm if desired. Pretty cool. It also has max pressure recall.

One feature the SPA has that I don't believe the others have is the ability to adjust the averaging rate of the rail gauge. You can get as detailed of a reading as you can get with a digital gauge.

Here is a pic (the Rail gauge is white-face):

 

what kind of numbers should I see or do I want to see for highs and lows

 

Should idle aroun 7,500 and you dont really want to go over 25-26k and the guage will only read accurately to 27,500. The factory limit is set around 26,500

 

well I know the quad rail gauge caused issues for me so I took it off. I was a nice gauge but it threw codes on my truck so it got taken off and sold. anything that I think is gonna hold me back gets taken off. I would like to get the dipircol and see how it does. I have had good luck with their other gauges I run 4 of them
