Re: Fuel pressure inconsistency run to run Aeromotive
A little further clarification----there is no difference in gauges of Autometer on the cowl and Aeromotive at the carb, they are consistent with each other. The car can sit still for an hour or the next day and have a different pressure everytime it is started and can be higher or lower from where it was at the last run. ??????

Re: Fuel pressure inconsistency run to run Aeromotive
fuel cell vented? Or had one system on a Superstocker that the fuel line had gotten sliced where the fitting was put in and the liner was getting sucked in when a lot of pressure was on and collapsing the line.
Took awhile to find that one and it was on a carb system. |

Re: Fuel pressure inconsistency run to run Aeromotive
You have the same system I run, what about voltage? Have a way of monitoring it, pump output will change with varying voltage.Merely a guess as I've never had that issue using their products.

X2, three very good areas to look at.

Re: Fuel pressure inconsistency run to run Aeromotive
What size needle & seat is in your Q-jet and what fuel pressure are you running? Larger N&S's don't like a lot of pressure. Also, how much pressure is at the regulator from the pump? One of my customers once told me he spoke with a Tech at Weldon and he said a Q-Jet should not have more than 18 lbs. to the regulator. Anymore and it "overworks" the regulator. Lastly, the ideal location for your regulator is in front of the carburetor, not to the side, and "soft" mounted according to Product Engineering. This allows inertia to work for you instead of against.

Re: Fuel pressure inconsistency run to run Aeromotive
If its the large N/S like Danny always put in ours, 5.5 lbs is about all they like . Some of them will go 6 , that's it ...

Re: Fuel pressure inconsistency run to run Aeromotive
Had customer pulled his hair out over fuel pressure,would be 6-7lbs. then next thing you now would be 2-3lbs then back. changed regulators 3X,checked pump out,looked OK,he bought a new aeromotive just like he had,same thing. He found out line was sucking together between tank and pump, just took him 2 weeks to figure it out.
