Reason for this is the aiur bubles in the isolators will give a offset. The whole isolator thing has been a problem with keeping a accurate number. Most people get frustrated and yank out the isolator because everytime there is a low pressure problem you must pull the isolator out to verify if the isolator is the cause of the fuel system. So most people install a needle valve and skip the isolator. Then you always have true pressure reading and if anythiny fails you can pull over and shut the valve.well there are no leaks now but i am getting two different readings the edge read 15psi and the gauge reads 13psi any reason for this
You mean this...Hey Mike, do you have a write up on doing that? My isolator and gauge work fine for a few months, than I loose the reading completely and have to pull everything apart and re do it. It gets annoying.
Also, my length of tubing is pretty long...so would it help if I shortened it quite a bit this time?
Thanks for your help.
