A single line tank doesn’t have any valves. The valves are in the primer bulb in it’s fuel line. . . 😎
That would make sense Garry!
I didn’t think about it until I had my dual line guts all back together,
but does the primer button pressurize the tank to move fuel,
or suck it up the pickup tube?
I got the homemade check valve disc to work good now. I must be smarter in
the morning. 😕 I realized the pickup tube protrudes into the check valve
body slightly, and the tube has a notched end, that keeps the disc from
opening too far, yet allows fuel to get into the tube.
I thought I had the original pickup screen pretty clean with wire brushing and
solvent, but decided to take the old screen out, and I was aghast at the amount
of crud in, and behind the screen. Decided to make a new screen!
Also, tore apart a rusty / crusty tank assembly from an OMC single line tank
to measure the O-rings. The two little valves behind the core plugs have
a tapered seat, and the o-rings I removed had a tapered ID.
Whether the taper in the o-ring was manufactured or just took that shape
from years of spring pressure on the tapered valve, I don’t know.
Anyone know for sure?
The closest I could measure these o-rings are…..
OD- .325
ID- .170
CS- .075 (cross section / wall thickness)
The closest I see in an O-ring size chart is OD- 5/16" x ID 3/16" x CS 1/16".
