I think I am right but I want to be sure. On my 02 I have a schrader valve on my vp44. I want to install my fuel pressure gauge at this spot until my fass gets here. Can i just screw in my Grease gun hose in after I take schrader valve with out needing a banjo bolt? So it would be vp44 hole, grease gun hose, then needle vavle/ snubber and then Fuel pressure sensor from quadzilla. 

PersonallyI left that open for a test gauge if needed later to check the in cab gauge. I teed mine off after the filter canister.

I'll put it back after I get my fass in. Would I need a banjo bolt if I do it that way?

As hard asI try I can't remember what the stock set up was. Seems the whole schrader valve unscrewed from whatever fitting was stock. If thats the case as long as the threads are the same it should work. I am thinking anything on that pump is metric.

Alright I think it will work but I wanted to be sure instead of ordering something I didn't need. I am gonna give it a try anyway.
