Had a hard start problem and a chugging problem for the first few seconds when I floor it. After a lot of searching Agostino Racing pulled off the vacuum line on the Aeromotive Adjustable FPR and when the ignition was turned on and the pump pressured the system fuel poured out of the line (Leaky diafram) So they change it and it ran fine for all the tuning and test drives.
I pick the car up go home which is 300 miles away. I started noticing the hard start again and and the car had no top end. SO I pulled off the line atthe top of the AFPR and sure enough it was wet. Then turn the ignition to the on position and out comes about a tea spoon of gas. I had heard Aeromotive had changed the design because of this problem.

QUESTION: I know this would cause the hard start but would it also cause drivability issues like no top end and a chugging when I down shift to 3rd on the high way hold it there for a second then pin it? Also anyone else have this problem? 2 times in less then 500 miles Should I get them to go to another brand?

Thank you, Jason

 

If its leaking it needs to be fixed asap. I had the stock regulator go out and it filled the cylinders with so much fuel that the engine hydrolocked resulting in a shattered starter.

 

FWIW, I have been running this regulator for 2 years now with no problems. What is your fuel pressure set at?

Hmm I dont know what its set at I dont have a FP gauge. It was set when tuned.
