im replacing a motor on my 99 speedster and was pulling the pulse line off the pump when the cheap plastic inlet broke. SBT tech guys said to order the mukini high volume pump and it would work but has 3 outlets on it. Has anybody used these and will they work ok on my boat? i was planning on blocking off 2 of the outlets and just using 1. whats the best way to plug the 2 outlets without getting any leaks?
