when my car is cold i get 39# of fuel pressure line off. 36# line on. when it gets hot it drops to 31# line off and 26# line on is the gauge just getting hot and losing accuraccy or is it something else? my o2's dont change and i have 0 knock then when i shut down till cold and start up its back to 39#. the fuel gauge is an aggressive rail mount, liquid filled. is it better to put a 60" line and mount it away from the motor. this sucks because i keep changing the fuel pressure back and forth from 31 to 39. because when i adjust after hot its up to 46# when cold PLEASE HELP!!!!!!!!!!!!!!!!
