M1078A1 fuel starting issue

[Ronmar]

well if the reg is the only thing providing the restriction and 2 different ones are doing the same thing, it is probably right. it just seems a little high from some of the specs I have run across...

Been busy but made progress on this today. Pulled the reg and pumped the primer, no pressure built up, just fuel pouring out of the port. I had already purchased a new regulator for $250 (cat 1420371)So installed that with new o rings. Pressure dropped to 55-65 at idle same at high idle but with less gauge sweeping. Gauge is dampened but sweeps around 60 +\-5 at different frequencies depending on throttle pos. I guess the other regs are different?

putting this to bed.

now onto the aux panel I bought to house my tach
