"I want to connect both my 90H

"I want to connect both my 90HP and 9.9HP outboards to the same 30 gal fuel tank. Can I just put a tee in the gas line near the motors and connect to the master tank, or will that cause the running motor to pull gas/air out of the other motor? Can I use a check valve after the tee to prevent back-flow, if so what kind do I get and where can I get one? Can I just use two primer bulbs both on the outboard side of the tee - is their check valve strong enough to prevent the running motor from sucking gas/air from the idle motor? I don't want to use a manual valve to switch between motors. Thanks for any help you can give - I've never tried this before."
 
"I think it should be fine, es

"I think it should be fine, especially with the two priming bulb idea. There are also check valves in the fuel pumps."
 
No need for the check valves i

No need for the check valves if two bulbs are used. They contain check valves. Should work ok.
