fitting size for autometer fuel pressure guage

I did a search on this; but couldn't come up with a definite answer.

I picked up an autometer fuel pressue guage on ebay for 20 bucks and built a bracket to mount it above the windshield and underneath the hood.

Does anybody know what the fitting size is on the test fitting on the fuel rail?

I would assume you could take the cap and schrader valve off and run a stainless line from the top of the fitting in the rail.

-4 AN
You don't say what engine you have but if you have a TPI you use one of these to clear the plenum and get the 1/8"NPT gauge port Installs without taking the intake apart. Cap the open end.

LT1 could probably go straight on with a -4 AN fitting

Though you were posting a reply to the OP's question , not asking a question of your own

You want to fit a 1/8" NPT sender unit on to the LT rail?
The adapter I posted in the link above will do that ;effectively a -4AN female to 1/8"NPT female adapter
