Re: how do you put this fuel pump kit together 1981 evenrude 115 hp
These can be difficult to rebuild.
Notice there are two screws on the fuel pump body that hold it to the block#7 in the picture. Remove those screws. Remove fuel lines.
Get over a table for disassembly.
Remove the big screw. Lay the parts in order on the table.
Remove the other screws while holding the pump together with your fingers. (There is a small spring inside that will try to push it apart.)
Slowly release and lay the parts in order on the table.
Reinstall in the reverse order. Put the long mounting screws in backward to line everything up as you assemble the pump. Use a thin feeler gauge or or light shim stock to keep the diaphragm in place when you put the body screws in loose. Gradually tighten them and then remove the shim. Tighten them all the way.
Test the fuel pump before you put it on by hooking up the fuel lines and pump the bulb.
Fuel should not come out of the back of the pump. If it does, disassemble and reassemble until it is right. When it is right, don't forget the gasket between pump and motor......... Whew hope this helps
