Mine runs about 28psi

 

Mine holds low 30s.

My 255 is doing the same thing. Sometimes if i cycle it twice it'll stay near 30, other times it bleeds off fairly rapidly and i get long starts on occation. I've change the regulator and nothing changed. I'm going to play with the pump or rotate in a #42 and see if i can pin point what it is.

 

Key on i have 36 psi... and it holds it, i dont see any bleeding off of pressure

 

Have any of your removed the sender and turned on the key to see what the gauge reads at atmospheric pressure? Should read 14.7 correct? Or should it be 0, PSIG or PSIA?

Mine reads 9 when sitting at atmospheric, off of the rail.

Any comments or feedback?
