I was looking to buy a fuel pump for my outboard but I cannot find any information about it. It is more square with an in hose and 3 out hoses. Any information would be helpful.
 
This is the pump I Am looking for.

It is telling you that there is no complete pump replacement from Yamaha. Buy items 31, 32, 33 and in effect you have a complete pump.
 
All Yamaha 30 HP two stroke models are the same with respect to the pump. Reason being is that the float bowl for carburetor #3 mates with the fuel pump components. Unlike other models that have standalone pumps. Just a different way to get the same results.

There is not much that can go wrong with these pumps.-----What is your motor doing / not doing ?

In order to keep the motor running you have to keep pumping the ball like a heartbeat. Cleaned the filter, new hose/ball and tryed it with different tanks. Works exactly the same, pump it and keep going, stop and after a minute it sputters and dies.
 
Rebuilt the pump with new diaphragm/gasket. Works 90 percent better. Now after 3 kilometers or so it bogs down and a couple pumps on the ball we are good to go.
 
Have tested it with 3 different tanks, one built with all new parts, no difference. Have a new high quality hose coming today and new fuel filter and housing. Defently better than having to hand pump every couple of seconds. See how that goes. Thanks for the replies.
