is there a way to tell if you need more fuel?

 

When the Needle is pointing at "E"

 

When you get on going down the road, and it starts to buck, need a little bigger lift pump.

 

mine does the bucking thing, but I thought that was the trans slipping? Will my aux. lift pump not help any?

 

The only way it will help is if the factory pump is in good shape. If it starts to fail, any aftermarket will be useless, and your sittimg on the side of the road. Factory pump won't allow suction, so the only way is to bypass it completely is w/ a FASS or AD pump.

 

whats your RP and how much fuel/timing r u adding
