What range fuel pressure gauge is needed for an 03 CTD? I have found lots of 0-100psi gauges but that seems a little high.

 

Watch for vender names here , you'll be most likly to get a kit [ do not have to make 3 trips to get all the pices-parts ] , I'ld give you the one I used , but the are out of buis. sold ?
Range on that truck is about 5-18 guess , I like to see mine gauges run in the middle , so that puts it at 30-40 , but again if you use one of the venders every body is using then then you also have them knowing what you need .
Home page here must have several ,

Hay moderator that might be a good items for the store here.

 

when my fuel system gets modded, my 0-35 boost gauge will become my 0-35psi fuel pressure gauge [will split the gauge and relable it].. gonna use an isolator so that will prevent direct diesel contact with the gauge, but i doubt that would damage it anyways. diesel dynamics sells a autometer phantom gauge with their logo that is a 0-35 fuel pressure gauge. autometer also makes an electronic 0-30psi fuel pressure gauge. isspro and pricol make 0-30 mechanical fuel pressure gauges too..

 

30 PSI will be the max you need. your truck will not see anything over 20PSI and thats with a 150gph FASS system. Running stock you will see between 5-8psi depending on how clean your fuel filter is or when your CP3 is about to crap out

 

I just bought the FASS 150 and do not have a box on my truck yet! Is this going to hurt anything pushing extra fuel to the motor and I guess the big question is it going to drop my mileage? Thanks for the help

i don't think it will hurt anything, just make it better.
your the first person i know who has planed ahead in the fuel pump department before getting a box!!!!!
