Fuel Regulator - ZR-1 Net Registry Forums

ROGER E · 06-08-2007

I think my fuel regulator which is located at the rear of the plenum is bad. I removed the vacuum line to it today and forgot to put it back, then started the car and drove down the block. The car didn't run very well due to the vacuum leak, but I thought that with out the plenum vacuum the regulator should'nt let any fuel pass at all. So if this is the case... is it possible that it is not opening enough during high demand? Or is this just an open or closed type device with no actual regulation properties?
