i got a bigger fuel tank for the yz450...
it straddles the bike and the sides go pretty low for capacity. that part is fine.
it came with two right angle fittings. each fitting is threaded on one side and barbed on the other for hooking fuel line to.
the directions say to screw one of them into the bottom of each side of the saddle of the tank, and connect them to each other with a piece of fuel line. this is all cool, it will make sure the two sides stay equal with fuel.
the question... how do i just "screw" these things into the plastic of the tank? there are no marks or indicators for where these things go... and i am hesitant to drill holes into a brand new gas tank when i have no experience with these fittings in plastic and am not 100% sure they will seal well?
