Anybody know the OD size of the schrader valve in the fuel rail? Looking for an adapter for my fuel pressure gauge that does not restrict flow the the sender. Any help would be great. I know the ID is 1/16.

Thanks.

 

sunpro@actron.com they may be able to answer your question or even get you an adapter for your gauge

 

It uses the same thread size as the valve stem on your tires.

 

HI!.... I used the fitting on the right in the pic and then ran -4 braided line to my fuel pressure guage.
