I have a jabsco 37202 marine bilge pump that I want to rebuild. When I took a close look at it is quite a state including severely corroded bolts holding the assembly together. I bought the basic diaphragm service kit but I also need to replace the four long bolts that hold the main assembly together. I bought some replacement m5x65 bolts but they are not the correct part. On closer inspection the originals are slightly smaller in diameter with a finer thread, I suspect they are an imperial thread bolt but cannot work out what the most likely size would be or find a bolt kit for this pump, only general rebuild kits.
