I ask because my Mr. Gasket FP gauge reads a strong 6.5 at startup, but then drops to ~2-4 once the engine warms up. The path is tank>canister filter> Carter P4600HP>in-line filter>Holley press reg>gauge>carb Thanks! Last edited by Mosin; 05/01/09 02:08 PM.

Often low or nothing at normal under hood temps. 1972 Barracuda - 5.7L Hemi, T56 Magnum 6spd - https://www.facebook.com/GoodysGotaHemi 2020 RAM 1500 [img]https://i.imgur.com/v9yezP9.jpg[/img]
