when testing LP pumps 1 undolt them from motor 2 squeeze primer bulb . result// seems gas is leaking out of the mounting holes to the pumps , not out of the hole that goes to block . Question Does the mounting holes have to be bolted together to do this test . motor bogs down at 3800 rpm ,, it just stops like the key is turned off , but pull back on the stick and it comes back . changed all filters new high pressure pump , new lift pumpoxs last year . what is the proper way to test pumps? thanks in advance !
