Can anyone recommend a good, adjustable, vacuum operated fuel pressure regulator at a good price?

Thanks,

James

James,

Look at the MSD-2222. It's really a re-branded Bosch regulator, and can be had for less than $70 if you look around. We used on on an Audi turbo motor and it worked great.

I am not so sure about this MSD 2222 fuel pressure regulator it seems to be for boosted engines. My engine is normally aspirated. I need 40 psi static with vacuum contol when the engine is running. Any suggestions?

Thanks,

James

JTVOLVO,

MSD 2222

From JEGS site:

Maintaining accurate fuel system pressure on any multiport EFI system is crucial to performance. MSD's Adjustable Fuel Pressure Regulators allow you to fine tune the fuel pressure to meet the demands of your engine and injection system. Both Regulators are adjustable from 36-45 psi with a flow rate of 9.2-10.5 gal/hr. The inlet and outlets are 5/16" and a jam nut is supplied for special threads on the bottom to ease mounting to a bracket. These rugged Regulators are free standing so they don't have to be mounted directly to a fuel rail and can be installed in any position. Fuel pressure is set with an adjusting bolt and is locked in position with a locking nut.

As per the description it will regulate to 36-45 psi with a flow rate of 9.2 - 10.5 gal per hour -boosted engine or not.

James,

When they say it's good for boosted engines, they are really just saying that it has a vacuum reference for the pressure. The 2220 non-boosted one, has no vacuum reference and is only good for TBI or injectors before the throttle plate. The marketing people apparently wrote the product descriptions and they don't really know how to present the facts in a concise and understandable way.

Yeah, you'll have to be careful with Summit's descriptions on these parts, they are not accurate, there are even inconsistencies between their titles, descriptions, and 'speclist'.
