Swapped out my kinked fox fuel rails for a set of sn95 rails onto my 89. While attempting to transfer over my existing schrader mounted gauge, I noticed it wasnt reading zero when disconnected. Hmmmm, betcha that could've helped blow the head gasket!
Anyhow, the gauge is the standard Performance Fuel Systems gauge where you can basically twist the housing to calibrate it to zero. There's a spot down below where you can see that the zero is basically a range, not an exact spot. Doesn't this mean the gauge can be off by a few psi as the needle starts to move?? Is there a better way to calibrate these?
Of course nothings that easy, and now I need to locate a very short adapter in order to mount this gauge at the schrader valve on the sn95 rails, which is actual rail mount as opposed to the fox lines where the port is on the supply lines. Can't keep it there, as a had to do a little creative twisting of the supply likes to mate up to the sn95 rails. Looks like part number 3280 from Autometer will work.
Why dafuk don't they make the gauges to actually thread right in?
Rant over....
