Fuel Pressure Gauge Install ?

[xcucv]

I am installing a Pricol (SP?) FP gauge on my 99 24v. Included in the kit is the isolation tubing for the cab. My questions are related to plumming the isolator tube to the fuel lines.



1. There are two caps on top of my fuel filter that I could use but which one, the one closer to the center or out by the edge. I would assume one is pre filter and the other is post filter.



2. Does anyone know the thread type for these caps. I know the isolator takes a 1/8npt but not sure on the other end.



Thanks in advance.

All I know is the outermost one is post filter and the innermost is pre filter.

Thread is 1/8 np no tape is used with brass fittings you can get at home depot or other home store (hard ware for us old timers) mount the sender /isolator off the motor use regular fuel line for this with brass fitting . LOL Ron in Louisville KYOo. Oo.
