A couple of weeks ago I had to remove my fuel
sending unit to replace it.
I didn't thing it through and the top of the tank where the sending unit came out has been left open since.
The tank was 100% full when I left it and it has been under 50 degrees (down to the teens) ever since.
Is there anything I should treat the fuel
with before I put the sender back in? I'm going back on Saturday to put things back together.
