yep....i set the diaphram before i filled it w/ fluid oh, well... im gonna give the 1/4 line a try and if its a "no go" , im gonna ditch the isolator.... - - - Updated - - - finally got-er-done...LOL Def use 1/4 line from isolator to gauge..thanks everyone for the tips and suggestions!!!!!!!

glad to help.... it came with 1/8 line and im gonna swap it with 1/4 soon as i find the right fittings... i went ahead and mocked it up tonight and when i first started it up...i read 11 psi at idle... then it bled down to zero....while it was running...??? dont know why, but i thought maybe some air still in it....sooo bled the guage line again and got all the air out..put it back together fired it up....reading 5psi at idle..WTH?? not really sure but im gonna upgrade to the bigger line and also pick up a test gauge so i can compare

thats a vulcan kit....bought the same kit a week ago

I figured it out with a little help....on my truck the brown wire comin out of the dimmer switch dims the factory gaugesi tapped in there! Dripley, you were refering to a tapafuse....napa had them when i went to get some stakons...thanks for all the help

Thanks..any other options???

Wheres the best place to pick up a switched hot for the guage light?instructions says dimmer sw but there's no where to land a wire.....thanks!

Thanks... Is a 1/8" needle valve sufficient to feed to my isolator?...i went by napa and thats the only size that they could order...now its gonna be next week before i can get my guage installed i watched your needle valve setup video..are you using an isolator??? If so, where did you mount it? thanks in advance

Anyone know what thread the banjo bolt on the bottom of an 01' fuel filter housing is??? I just recently purchased a isspro guage kit and am wanting to install a needle valve there to feed my isolator.....thanks in advance
