Don't know if this happened to anyone else but if this helps just one person it is worth posting my fix. After doing the Hutch and Harpoon mods I had fuel seeping from around the fuel fill tube after filling the tank. I guess I wasn't cautious enough when replacing the tank. So I removed the tank again and used a 2 part epoxy that came in a Napa heavy duty fuel tank repair kit. Just brushed it on all the way around where the fill tube entered the tank. After filling the tank and running around for several days there is no more seepage. The gray stuff around the fill tube in this pic is the epoxy I brushed on.

 

i didnt have that problem..but it is good thing to keep an eye on...thanks Robin...
