To supply 2x150s at full chat via a single line will need a fair size hose. Depending on the size of the pickup in the tank you might be on dodgy ground. My 115 etecs have 3/8" individual hoses via separate tanks. I'd think you ought to be looking at a 1/2" feed if not larger (not done the maths to work out the equivalent csa) If all this is being fed via a 5/16" pickup.......
If you starve the engines, they can run lean & you could melt a piston
