Can I run 2 motors off 1 fuel tank?? (port tank developed a leak)

[crazy charlie]

Hope all reading this are staying safe and are well.1988 twin 5.0XL with alpha drives.Bad news as my port fuel tank has developed a leak.Aluminum tank that looks nearly new has developed a leak in an inacessable location.Going to drain ,clean and abandon the use of this tank for this season and deal with it next year.I have attached a pic of my fuel junction.Can I hopefully run both motors off of the stbd tank..?? Leaking tank cannot be removed without a major project that cannot be addressed this year.Take a look at pics,thanks Charlie

Yes, use the fuel valves to select the tank, but be aware of a lean fuel condition and high throttle settings

yes, those are crossover valves designed for exactly that purpose. I’ve heard of people filling the bad tank with water to eliminate any gas fumes.

Sounds like good news.Any idea of the valve handle position to achieve stbd tank for both?

I would recommend disconnecting and plugging the line from the bad tank if you do that. Nothing worse than accidentally opening the water tank to the engine... :facepalm:

Identify the fuel lines and we can tell you... (which lines come from what)

Left valve is port with bad tank,right is stbd with good tank and want it to run both motors

And which of the hoses on each value is to the engine, and which from the tank?

 

[crazy charlie]

lower lines run to engine and upper comes from tank

I found your valves online, but I couldn't find any diagram to indicate if they are T-ported or L-ported. Based on the configuration in the picture, with the crossing pipe between them, the only logical reason would be if they are T-ported. So, assuming they are T-ported, and the handle points at the tee drilling, then the following positions would have both engines running from the stbd tank.



It appears that the configuration at the moment is each engine running off it's 'own' tank.

As I said, this assumes they are T-ported and the handles point at the tee drilling. I would remove one valve and verify.

sounds like it makes sense.Yes my pic has both motors running off their own tank.I will give it a shot.Thanks
