I have an rv that lost its prime in the fuel lines. I tried to siphon, but could only get a trickle. I know there is gas because I put 3 gallons in the tank.

Could be a clogged-up fuel intank pick-up sock/strainer and a defective fuel pump/fuel filter

I put an electric fuel pump on and I can hear it so I dont think it is the fuel pump, but the in tank pick-up sock strainer is it accessible without dropping the tank? Oh and thank you for your reply.

Sometimes a fuel pump will humm/buzz but its not producing fuel pressure -check the fuel pressure with a fuel pressure tester if its within specs

I was told there are two kinds of electric fuel pump one that pushes and the other draws is this true? Thank you again for your time.

Disconnect the fuel hose at the fuel filter and slap on the gauge and read the fuel pressure and get back with the readings

Fuel pump pushes/draws fuel it depends on howow the fuel system is set up-could be high and low pressure pumps, again it depends
