Alright last fall i bought vulcans isspro EV series gauge kit and it had a mechanical fuel pressure gauge and i have had nothing but trouble i had alot of trouble with that pos ends and had a guy that used them to do 100+ psi things and had no trouble and he had trouble. After ever 2 months it will start ticking very annoying and i have to refill the isolater with windshield fluid and it will work fine. I looked for leaks and can not find any. under the gauge there is dust so it doesn't drip there so i have no clue where it goes. Now my question is does isspro make a electrical fuel pressure gauge that would match them? If so i am going to buy ASAP because i fixed it again and it is just ticking after 50 miles. What a POS!! srry about the rant i am just getting fed up.
