i need to run new fuel lines on my 94' DT40, but i do not know the I.D. of the standard hose. can somebody help me? also, what's the difference with marine fuel hoses?
I guess as long the hose fits over the nipple of the carb/fuel pump etc. it has the right inner diameter.
I use automotive fuel hose, it is much cheaper.
The Suzuki fuel hose thinner and fits better in tight situations.
