I got the AM FP gauge,
where do I hook up the sending unit??
I have a HRC under the hood gauge can I take that off and plug the sending unit into where the gauge was??

For the HRC gauge, did you take the vavle steam out of the fuel rail service point?

Probably..

And yes, that's where i have mine plumbed.

Well from the stem a line goes to the Vorech S FMU and the HRC gauge is tee'ed off of that line...

So put it in place of the HRC gauge. Or, buy an Earl's fitting (don't know the site URL) fuel distribution block and put the sender, SFMU and HRC FP gauge all off of that.

is it the electric AM FP gauge?

for the sending unit, i removed the shrader valve off the fuel rail, then used a compression fitting that screws onto where the shrader valve was, onto a small line that runs to the sending unit. then just run the wiring.
