Re: [OMC-Boats] 1969 buick v6 omc coil

Have you tried adjusting the float on the carb? Beyond that I think you could get a standard length of fuel line at any auto parts stor and a cheap bender to bend up a new one sans kinks....or get a stainless fle line (also just about anywhere) with some AN fittings you will need some adapters but any parts guy can help you out

Good luck

Ok, to be more specific, I have been having an issue of when my boat is wide
open, it starts to sputter and seems to be gas starved. What I have done so
far is:

1-Replace gas line.
2-Install fuel separating filter.
3-Install new fuel pump.
4-Install new gas line from pump to carb.**
    Mechanic put a small, but noticeable kink in metal fuel line. It
appears that it could be restricting.
5-Changed plugs and wires.
6-Cleaned carb.

All of this was done in order to stop fuel starvation issue, but to no
avail. :(

This is the 2nd season out on the water, and I need to get to the bottom of
this before I spend more money on my mechanic.

I'd like to change out the kinked fuel line to a flexible line to avoid
kinking, where can I find one? Also, could my coil be shitting out at high
rpm, causing rpm loss, which would cause the mechanical pump to fluctuate
starving motor for fuel?

I have posted questions in the past about this, but figured that a list as
to what has been done might help solving this issue. My mechanic also
suggested it could be from a check valve in the gas tank?

Any help would be grateful in solving this issue!
