Which one should you have? It seems logical just to have a rail gauge since this is what we are all trying to protect right? I was thinking about getting some gauges for my stock truck and want to get what I will need for future mods...

A rail pressure guage will not tell you if your fuel pressure is low. So to be honest you really should have both

Who is carrying the rail pressure gauge?

Doug Leno I think the address is dieselspecialtiesllc.com.

If I had to have one or the other Id get a fp guage, its a lot cheaper and I think more useful until you really get to bombin or runnin your rail dry.

If you got the $ get both, if not id get the fp now and get the rp when you can.

Seems to be hard to find...DiProcol rail pressure and fuel pressure gauges have been on order for 2 weeks and still haven't showed up.

CD in NM

Both on mine. Doug is a great guy, he will take care of you.

I guess I forgot to mention it so I'll say it too, Doug is a great guy, even emailed me a couple weeks after I got my guage in just to check up on me and see how I like my guage.
