    As we all may know the 69 rivi has the electric fuel pump in the tank. My question is if i want to go to a manual pump on the block would i have to remove the electric pump from the tank in order for it to pull??

    Im not sure what the advantage would be:Do No: . The problem with running a mechanical pump is that the fuel lines are on the right side of the car and the pump is on the left side of the engine. So you would need to run a rubber line into the frame rail, past the front suspension, through the engine cradle and out to the pump. Seems like just replacing the electric pump is the lesser of the two evils. Takes very little time and you dont even have to drop the tank.

    and to add to what Jason said, a 1986 Ford Ranger pump works well and I used an Airtex FS100 strainer to replce the "sock" on the pump, the FS100 works better than all the others I've seen used

    The pump has not went out on me, I just dont like the electric pump does the pump stay running and pumping at all times while your driven, or does it turn off when the pressure gets to a certain point?

    Ive owned my 69 Riviera for 27 years and Ive never had an issue. Its a low pressure pump. Maybe puts out 5 psi. The pump will stay running as long as the engine is running. The pump is wired to the oil pressure switch from the factory so if the engine has no oil pressure, the pump will stop.

    Just stick with the original '69 electric pump, unless your looking for a 'make work' project ? :Do No:

    You can also get your sending unit rebuilt and when you install a new pump (they are still available) your system will be spit-spot.

    If you ramp up the performance you will see that the stock pump can't keep up, and the Fprd pump works well there.
