OK, reading about E10 and fuel lines has me running scared. I have good fuel lines, but as I have read, not a good primer bulb (no E10 proof bulbs)

So, I need to replace mine as it is original.

I am not able to find the ID of the small hose that comes off the bulb. Input line is ID of 3/8 OD of 5/8 and the output line has a OD of 1/2 and I have NO idea of ID of line.

Anyone know size or where I can get the right bulb?

Thanks

Carlos
