1931 devaux fuel pump

Recommended Posts

Does anyone have and old rebuildable fuel pump for a 31 or 32 devaux.the devaux I recently purchased has an electric fuel pump with a block off plate,I’d like to get an original pump and use the electric as a backup.i believe the pump is a Stewart Warner 506 n. Model pump. Thanks for looking

well a lot of pumps are quite similar,  I have found one big difference is the pump arm.


You  need to determine the bolt pattern and that is the first step, then work on the arm needed to reach the cam lobe.


here is a link for your pump but we can't help without the bolt pattern for mounting to the motor
