pulsation dampner

ok i was leaking fuel under the uim and i found the problem and it is the pulsation dampner. There is a screw in the middle of it and if you have the screw all the way tight the dampner is all the way open if you have the screw all the way up it completly closed and no fuel is let threw. my question is is there anywhere i can buy one or anyway to get past it?

There's a pulsation damper there for a reason, replace it with a new one.

The screw is to limit the travel of the diaphram in the PD. Screwing it all the way down or removing it is the quickest way to distroy the PD, leading to fuel leaks and possible lean run conditions.

No, you are being a dick. I guess you think you are better than anyone else.

What? Is my time, or the other forum members time less valuable than yours? You must be pretty f***'n important. Why should we bother to answer your questions when you can't be bothered to spend one minute to do a search?
