My setup is: tank- -10 line-aeromotiv filter- -8 feed line- rails-aeromotiv regulator- stock return line on a '85 GSLSE (about 1/4 inch tubing)

what the car is doing:
1. It won't start right up unless push the gas or keep it floored......seems to me like it's overflooding

2. When turn the key on for the line to charge, the pump sounds real loud and pulsates(I mean really loud), after it charges it settles and is not as noise.

3. The worst part is when the car starts moving if not accelerated hard enough the car will start jerking, it repeats this behavior in pretty much every gear. If cruising on the highway and let off the gas just a bit, the car will jerk.

4. The pressure gage on the regulator pulsates continuosly while the car idles,....somewhere betwen 25 and 30 #

5. When accelerating hard and then let off the gas completely the car will detonate and become a dragon with flames as long as 4 feet.

The car works great as long as you are driving it hard.....try driving around town in it or just cruise and it becomes a pain because it pretty much jeks all the time.

An idea that came to mind was the it is overpressuring the return line due to it's small size.

Any ideas?

 

tuning?

and, get some better return lines.
