Aqua hot leaking diesel

[contrail Bob]

Hi all, We're at SPI and I've noticed that my AQ is leaking fuel. I took the
main burner off and it looks like the outside seal on the fuel pump is leaking a
lot of fuel. has anyone replaced this pump or can I just replace the seal in the
pump???? It was leaking a small amount when I left home, I tightened all the
screw's and that seemed to fix it. Before I arrived here at SPI I filled the
fuel tank on the bus and now the leak is big time, it leak's without using it.
Thanks.
