where do i tap into fuel line to put on gauge

 

you can tap into the schrader valve on the VP, or on some of the earlier 24v's there is a port on the fuel filter housing. mine is at the VP.

 

its 1999 forgot to put year in

 

I have a 98.5 and I believe they are the same. You have two options you can choose pre filter or post filter. I removed the fitting on the top of the fuel filter housing that was closest to the engine and that gives me fuel pressure after the filter. This will allow you to monitor how dirty your filter is getting. Its also handy in the extreme cold to see if your fuel is gelling up. IF the pressure starts dropping add more power service.

I went with high flow banjo bolts, I got 2 that were drilled and tapped, shrader valve in one and fuel pressure guage
in the other, post filter. Here is a link to a pic, I didn't get them from here but many companys sell them.

Geno's sells just a single one and they are great to deal with.
