Fuel Leak from FFM

[Big Green]

Been a while since I've been around these parts but ol big green has been serving me well.... well until now.

Fuel leak from the FFM. Yes I know I could update it and do a lot of other things however with hay season right around the corner and horses that need to be transported I need to get this fixed ASAP.

I haven't pulled the FFM apart however I understand the heater in the bottom is o-ringed.

Anyone have a source for said orings, or size/spec's to buy local?

If downtime is a factor, be sure to have an entire replacement assembly (OEM, or of any flavor) on hand before grabbing a wrench. When the FFM leaks, it's usually fatal, either failed potting or housing crack. Time-wise, an OEM replacement would be the quickest and simplest, having no consideration for accommodating a foreign agent into the system. If your leaking FFM is original, praise its quality for lasting this long. Its 30th birthday is mere months away.
