Fuel pressure regulator question

[96cobra_12]

Just got a new pressure regulator from Kragen. The new FPR only has one O-ring, Stock has 2. I that ok? also the new one came with the gasket but not like the gasket on the stock one. Which one should i use?

Pic: Stock-Left with round gasket. New-Right with oval gasket.

use the one that came with the new one and one o-ring is fine.
my Kirban has one IIRC

ok. should i keep the old gasket in its little cutout or remove it all together?

I would be inclined to not use it. If the new FPR required a gasket one would be included in the kit. The gasket may prevent the fuel line from seating as deeply as it would otherwise. I would also confirm that the gasket was just not missing from the kit.
