anyone here put a fuel pressure guage in----inside or outside?

 

nhra says it hasto be outside, summit carries an autometer adapter for $8.00 and a summit gauge for $17.00 that screws right into the schrader valve on the (passenger side on the fuel line) the gauge is liquid filled and works great..

 

Mine is inside but it's electric.

 

Thanks for the info--i purchased all the guages from Ford Racing--boost,fuel,oil press,water temp and Ford Racing Tach
I guess ill have to run the 170.00 isolator to put it inside
Thanks for the info ill probably use that location to get some fittings to fit
