Hey all. I'm going to be installing a fuel pressure gauge in an 01 Dodge and was wondering where I should put the isolator? I normally put it on the inlet side of the injection pump, but he has the big line kit with the JIC fitting. Should I get a tapped banjo bolt for the outlet side of the fuel filter housing? I believe that it is a 12mm bolt, but can't remember for sure. Thanks in advance.

I like to out it in the line from the fuel filter to the injection pump.

The fitting sizes are 12x1.5

I did mine a little different I ran the 1/2" big line kit to the inlet side of the stock fuel filter (on the block) then ran a 1/2" stainless braid line kit from Vulcan from the outlet on the filter to the VP. The FP guage runs on a tapped elbow fitting off the filter to the stainless line so I have about 11" of 1/2 line between the gauge port and the VP inlet...also I have two fuel filters/water separators with the FASS which has saved my bacon on more then one occasion.
Hope that helps.
