I purchased new pump to filter fuel line along with making a new 5/16" line from tank to pump.
Its then I noticed there are 4 threaded holes of different size on the fuel pump.
Top threaded hole is smaller and finer threads, like the ones on fuel filter.
Bottom threaded hole is 5/16" flared tube fitting type
Found another stock 55, their lines used the bottom threaded holes.
Why 4 holes, one set needs plugged or what do I do. Manual says nothing?
Thanks
