Some liquid filled gauge don't read well when they warm up. Dave d1_bradley Mar 16th, 08, 11:53 AM Your pressure can also vary depending on your installation. You will get a more stable reading using a relay and proper sized wiring to the pump. If you skimp on the wiring, the pump will "slow down" as it heats up. nhrafan56 Mar 16th, 08, 12:29 PM yea its liquid filled '67 427 Mar 28th, 08, 1:22 AM Running the same pump and also seemingly loosing fuel pressure at the the carb W/ a liquid guage [cheep $ Jegs brand]. I get a decent 6.5psi at start up... Drops to 2-3 after warm up. | ||
