The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
what size fuel line should be on a 2002 2.6liter
200 hpdi? changed my primer bulb and was surprised to find 5/16 fuel line? i assumed 3/8 would be the norm.
Yes, it should be 3/8....but boats are rigged by manufacturer, not Yamaha...who built your boat? And you need to replace the line from tank to engine, complete. If you starve this motor for fuel, it'll die.
xpress bassboat. had 5/16 all the way through.
i had installed a moeller fuel water seperator and since
then the primer bulb would not stay primed. the filter
had 3/8 fittings so maybe this is why im having
troubles?
I would certainly change it all out and you MUST use a 10 micron filter, either Yamaha or a couple of others.....should be at least 50 gal/hr rated, 90(yamaha) is better.....you could put a vacuum gauge in front of engines filter with a 't' fitting in fuel line to see what vac. is on line...if over 2 1/2 @ idle or 4 1/2-5 @ wide open you have a problem...and I would be surprised if you don't....
i agree the moeller doesnt have much info on it
about flowrate. filter is gone now i will go back
to running with out one for a few weeks see if
i get this straightened out.
