Macerator extension cord

I want to make an extension cord for a macerator pump. I want to add about 10 or 15ft to the existing cord so I can reach the TT battery. I plan on using 10 gauge wire. Is that big enough? I would like to add an inline fuse. What size fuse would be correct?
Has anyone made their own 1" extension discharge hose or is 3/4" all I need? Any suggestions would be appreciated.

You haven't told us which macerator pump you have but instructions for the FloJet I have call for 10 gauge for a 10' to 20' run. However, I had some 12 gauge zip cord in my workshop and used it for the run from the tongue back to where I mounted a Bargman connector next to the waste gates, about 20' ... been working fine for years, no issues at all. To protect the cable I ran it through a length of black hose that's zipped tied to the trailer frame. There's no need for additional fusing with the FloJet as there's a 20 amp fuse in the switch handle. The run from where my FloJet is located to the sewer intake stack I installed on the house is ~ 50' so I use that length of 3/4" hose, as recommended by the manufacturer. I'd only use a larger diameter output hose if the run was much longer, over 75'. A series of 10 pics start here.
