Re: fuel line help

The Yamaha was fitted with am 8mm hose which is equal to 5/16". V-6s should have 3/8" line.

Re: fuel line help

It should not have much effect we are only talking about 1/16".

How is the fuel pump on the 150? You are going to have to start from scratch.

Compression
Carbs cleaned
Spark

Do you have a primer bulb? Try pumping the bulb at WOT throttle and see if that makes a differance. If it does then it is the fuel pump.

Just for fun go to the larger fuel line ..... they are not that much money.
