So I'm running dual wahlbro 350 pumps in a 03-07 fuel bucket with -8 feed an -6 return an a aeromotive fpr. Well so far I've blew a line off the pumps in tank. But when it's really cold (I live in Alaska, so cold is below 0) my Fuel pressure gauge reads 100 an stays pegged out until the truck has ran for 30 mins- an hour some times longer. Has anyone else had issues with the aeromotive regulator with temperature fluctuation?

 

Anyone??

 

Call Aeromotive.

 

Does it run like crap when the pressure reads high? Have you tested with another gauge?

 

^^that would be my thought as well. It would be pig rich at 100 psi, and I'd be surprised if it would even idle.

 

Generally it surges until it finally dies. Or sometimes it'll stop surging and idle normally. I haven't tried a mechanical gauge only my glowshift maxtow electronic fp gauge. And my aem wideband took a crap on me so I'm not sure what afrs when it's doing all this right now.
