sorry for the crappy pic its the only one i could find right know<br/>

Didn't it come with instructions? Whats the application? What psi are you shooting for?

no instructons. stock fuel pump goin to a 48 ida i wass told to do 7 psi i hooked up the line to both fitings and nothing. i have a clear filter temp hooked up right before regulator the wierd thing is that when i losen up the clamp on the regulator i hear air coming out and the fuel filter starts to fill up like if the regulator wass completly seald.

What psi range is the reg designed for? The ones I saw on ebay that looked like yours were all
20-140 psi range, and that wouldn't work.

BTW 7 psi is a bit high for a weber.

i dont know ill try to find out but that would explain alot right. whats your opinion on the right psi for a weber

it says 0 to 140 psi

Weber needs 2.5-3.5 psi. Throw that regulator in the trash

cool and i really doo feel like seting fire to it then trhowing it in the trash thank good i have a low presure one on the way

This argument on twins is still going? Once again I'll put it on the table. Send me a set of your sp twins and i will dyno them back to back against a set of bnrs on the same car on my Mustang dyno. Only thing that will be adjusted is the fuel table to keep afrs the same. If they make more power ill gladly be sold on them. If not ill send them back.
