Just wondering if you contacted grippa about the recent problems you had with your heater
1. the leaking diesel
2. the melted fuse
As this is in addition to the problem you had with the fuel tank connection when they installed it, I am curious as to their response. They should reimburse you the money you have spent so far resolving the diesel leak, and be able to advise of the reason for the fuse melting.
