Q:
Mine has 3/8 on one side 5/16 on the other,suggestions?
A:
We do not have a primer bulb that you can mix and match sizes on either side like that. You will need to check locally for that.


Q:
Will this fit Mercury 500 50HP Thunderbolt 1974 motor, S/N 3821781?
A:
The primer bulb is universal. It will depend on your hose size if this will work with your set up.


Q:
What size fuel line on a 1989 Force 85?
A:
We would need to know engine model number in order to confirm. Contact us at the number at the top of the page with that info and we can look into it.


Q:
Will this fit 2010 Mercury optimax 90?
A:
We will need serial number in order to match up primer bulb for your motor as we need to cross reference OEM number.
