930 fuel pumps

Front pump sends fuel through filter and accumulator to fuel distributer.

Front pump does not "prime" rear pump - has no connection whatsoever.

Rear pump scavenges excess fuel from system and pushes it back to fuel tank through return line.

Bad front pump results in not enough fuel to distributer - mine is 106 lbs.

Bad rear pump results in build up of excess fuel and fat condition.

Wire each pump on separate manual circuit with 25AMP fuses and proper quality toggle switches.
