Also: Since some of you may not have seen my fuel regulator recall note, Iβm pasting it in below:
Many of you have re-fitted your LBCs with aftermarket electric fuel pumps, and usually a fuel pressure regulator. If you have a "Purolator" or "NAPA" fuel pressure regulator, you may want to read the notice below. My race parts supplier (RacerPartsWholesale) send me a note about this last week....two of my cars have these regulators, and one of the devices was built during the affected interval, and will need to be sent back.
Number of Units Affected: 32518

Consequence Summary:
