Slow bleed down adjustable fuel pressure regulators that act like a check valve?
Which adjustable regulator also acts like a check valve? I have to prime the key 3-5x to get the truck to start without extended cranking. I've tried different pumps, I do not think its the pump. It might have something to do with the Walbro 450 having to fill large -8 lines but I also think it might be the regulator.

Regulators wont hold pressure in lines.....my big ***** looking aeromotive regulator bleeds off just as my magnafuel did
If you take one apart youll see rhere is nothing to keep pressure there youre only restricting the flow.
Even big single pumps bleed off pressure

Im in the same boat aswell with this. I run an aeromotive 340 intank and have the aeromotive boost referenced regulator and i most of time have to prime mine a couple times aswell and truck fires right up. Otherwise a single prime and flip of the key turns over numerous times before firing. Ive wondered about a check valve aswell for this setup!

Having no air in the system and slight pressure will give instant full pressure and starts the same as stock, instead of having to refill and then pressurize a system that has drained because of the aftermarket regulator.
