I'm in the process of rebuilding and upgrading a 92 z-28. I'm going back in with an adjustable fuel regulator. Can anybody tell me what the normal pressure would have been with the stock reg. I need some guidelines to go by to set the adjustable reg. I was unable to take a reading before because the engine was not in running condition.

 

not too sure but i think on a 89' it was around 43. Hope that helps a little.

 

FYI. Just remember to do it without vac. hose hooked up. I think the new car carft has an article on TPI tech this month in the back of it.

 

Thanks for the info, I'm gonna see if I can find this months Car Craft mag, today. Thanks again

 

Stock fuel pressure is 36 PSI when you turn the key on and 41/43
PSI running at idle.
