I am going to go with the Dipricol gauges. I think they look good and they are accurate. Anyway as for the fuel pressure guage they recommend this...

Important Note!! This is a mechanical gauge and in order not to have raw fuel coming to the back of the gauge in your cab, we highly recommend that you purchase the fuel isolator kit below - click here

Should i get the isolator kit or is it somthing that i don't really need to worry about? Thanks! Paul

Do you like the smell of raw diesel? I just installed a new fuel pressure gauge with isolater a couple of weeks ago, last weekend I noticed a slight leak from the guage just need a slight nut tightning. Glad I had the isolater!!!

 

I wouldn't run one. I Just have a needle valve so if it does leak, you can shut it off. I had a leak a few months back and I just turned it off for a few days and it hasn't leaked since!
