Have a 81 924, has been sitting for years. Just decided to get it ready for my daughters 1st car. Both fuel pumps are seized. I remember readingsomewhere that prior to 79 only one pump was used. What is the purpose of the internal pump? The external pump inlet is level with the sump.For ease of replacement has anyone tried a aftermarket external pump and ditch the internal. Accel, Walbro or any other external high pressure pumps are readily available and cheaper. The only scenerio I can think or requiring the internal pump might be high G cornering with a low fuel level. Someone stop me before I cut the internal pump out and stop by Summit and pick up a Accel pump.
