Dave, I may have a non-constant duty gauge. It is a cheap combo vac/pressure gauge from Actron - CP7803
The way I had it hooked up before was a 90° barb on the other end of the hose that was 1/8" NPT male into the manifold.
Here's what I have now...the problem I recently noticed is I musta whacked it, the barb on the gauge is cracked.
Let's see if this pic works -
I see Sunpro makes a nice 2" vacuum gauge (CP7978)..I can pick it up for almost the same price locally as I can at Amazon..it has a 1/8"NPT connection.
Changing the subject, I also noticed my "Mr. Gasket" #1561 fuel pressure gauge reads about 1 PSI at rest..is there a way to zero these gauges out? It is a little unnerving to see 4+ PSI on the fuel pressure gauge..and I don't want to have to remember to scale it from 1 PSI, espcially if I am troubleshooting fuel issues.
