OK! I understand that the VF500F worked better as gravity feed. Too many fuel pump failures and such. So I do know why the fuel lines were made into gravity feed for my miniceptor. what I don't understand is why, right off the petcock, coolant line was used, trashing the filter and the rest of the lines, yes those were fuel lines. and then! I found out 3 different size lines were used. can I possibly talk someone (read ANYONE) to tell me how they did theirs if they did convert to gravity feed. and I really want details, ie size of line, type of T, filter type/size. and then maybe try to talk someone (again read ANYONE) into furnishing some pictures to help me along. thanks all for taking the time!
