    will 3/16" fuel line be ok 99 gp800

    Changed all the lines out to 1/4" but was having leaking issues and almost impossible finding clamps small enough to seal especially locally so I went to 3/16 which slides on real tight but seals I know the factory size is 5mm which is impossible to find and 1/4 is 6.1mm which is larger and 3/16 is 4.85mm which is just a hair smaller but a way better fit I just want to make sure I won't starve the fuel supply and blow it up

    mcmaster carr sells crimp clamps like this that should work for you.

    but to the ops question the 3/16 will be fine.

    Cool cause the 1/4 line slides right off with little to no effort while the 3/16 actually fits nice and tight over the flared part of the nipple where it is supposed to seal where the 1/4 would rely on the clamp to seal it which is actually not the proper way
