1997 dt150 suzuki fuel line

[micel]

Im replacing fuel line from tank to seperater,it now has 7/16".The largest Ive seen on a outboard is 3/8",could the larger diameter cause any problems?Ive also been told to put a electric fuel pump in line would increase performance,is this true? Much Thanks Micel

electric fuel pumps are not good

Thanks for input JIT,I wonder how much head pressure the oem outboard pumps can take because I have seen quite a few little 4-7psi,and 35gph pumps in use on bay and bass boats.I think the idea came from some body seeing one on a larger boat which would require a 25'+ run of fuel line.I guess I'm going to go ahead and rerig fuel line with 7/16"ID,the only difference I can think of would be increased flow,I've just have not seen anything larger than 3/8" on a outboard.

I would stick with the factory fuel pump. The 3/8 line should not make much of a difference, if any difference at all.
