Hello everyone again! I just cleaned the fuel pump in my R4 and I wanted to order a spare one now that I have it out of the car. However, I am having trouble finding the right one. Mine is the one in the first picture and the closest I have found is the one on the second picture (whose flange has a slightly different shape). Will I be able to fit it in despite the difference? Also, I am trying to fit in a fuel filter since apparently neither the fuel pump nor the carburettor had one. Where is the best place to fit it? Is it between fuel pump and carburettor? Many thanks in advance.
