31 PSI with the vacuum hose connected, 39 PSI with the vac hose disco'd.

 

I'm pretty sure about those.

Well I left early today and didnt get the info about the vac hose off /on, but i did check pressure. it was a lil over 36 with key switched on. with it running it was like 39/40ish range.

 

Is that to high?

the regulator is like 40 bucks IIRC, mine was spewing fuel so it got replaced.

I think you misunderstood me,, I was saying it was 36 PSI and around 40 PSI

 

But thanks,,,jt

Your PSI is in the ballpark, and should be sufficient.
