I was wondering, Has anyone had the Main Fuel Pump fail & run Home on standby ? 
I heard You should put a in line hose & bypass Main to do this ?

[Terry T]

If you speak to the experts at Carter, they recommend this as well as a bypass w/check valve at the electric pump.

Some people say you should run the electric pump only as a boost pump as necessary if you are going run the lines thru the original fuel pump, the reason is if the diaphram in original pump should break or leak it will fill the oil pan with gas. People who want to run the electric pump all the time remove the original pump and put on a block off plate.

I had an electric booster pump on the 1951 Kaiser Business Coupe.  As the gas started percolating and the engine began to sputter I kicked in the switch to feed the fuel system from back by the tank.  The flow rate was about 2 psi over the vacuum pump at best performance so I wasn't worried about blowing anything out and worked fine.

NOTE:  Unless a fuel pump gets rebuilt to CURRENT component part material standards (can withstand effect of 10% alcohol gasolines), even a brand new in the box pump should be considered useless other than for a core to rebuild with the current component parts.  Depending on how much you drive and how long gas sets in the fuel system with the vehicle at rest (engine not running to move fuel through system) you could lose seals in a relatively short period of time.
