Amazon.com : low pressure electric fuel pump

This should help you out. I like to focus on the below 4 psi pumps. Get above 5 and their is the risk of overriding the float valve.

Where do you mount the electric fuel pump, near the tank or near the carb ? How are you blocking off the area where the old pump was attached to the engine?

Thanks

mount the pump were it is convenient. Location not critical. And just leave the old pump in place. Won't hurt anything.

And the spam post above mine has been reported.

Have you found a need to run a gas line from the electric pump back to the tank to relieve pressure and not over stress the carb?

no, if staying below 4 psi you are within the working pressure of the original vacuum or mechanical pumps used on small engines.

As stated by ILENGINE, 3 psi is perfect.
