Isspro has been making guages for close to 100 years - they know what they are doing. In most case when you have fuel pressure problem - the problem is with the installation and not the guage.

 

i was not stateing that the gauge was wrong, i an unhappy that when i purchased the "kit" it should have came with all the componets to properly hook it up like the extra 2 foot of "greese gun" line and the needle valve. but i do like the fact that it came with a potentiometer for the dimmer!
