Who makes a fuel pressure reg that doesn't leak off

[Tonysnoo]

I know the stock cat one keeps pressure in the system after shut down. The cutler adjustable did.

My mallory bypass regs didn't. My holley bypass reg doesn't. Did I just get duds or do any of you know of a reg that will stay pressured up for a little while(10-20mins)

Thanks

Bosch regulators will hold. Have you looked at the diaphram in the old regulators?

Customers need to be carefull some Bosch regulators become a fuel restriction when used with 190GPH or larger fuel pumps.

If they hit pressure and hold it shouldn't matter. leak down after the fact would point to a leak. 20 min leak down and it could be a very small leak that would be hard to find.
