Fuel heater leak

[RTRAM]

I just noticed that I have a leak around the fuel heater. I have the remote fuel system that I installed a few years ago. . maybe 10 or 15 years ago. I am thinking that the O-ring that may have just gotten old with time and is starting to degrade. I checked and the adapter was tight.



It's a little difficult to work in ths area, I was using a mirror to see what was happening, so I would like to have any parts on hand before I tear it apart.



Has anyone had a fuel heater that leaked?



Does anyone remember what kind of O-rings were used for the 93 adapter?
