1000w digial Ballast fuse problem? Help.

1000W Digital Ballast has an inline fuse Glass type. I didn't realize I had a Hood / bulb problem which caused my ballast to over heat and it actually melted the fuse holder in my ballast. I removed the fuse holder and direct wired the ballast by-passing the fuse and the ballast works fine. I know not to run it without a fuse, but I can't find a new one or mybe a button type fuse.

The Question is where do I get a new 20a fuse holder for it? Any suggestions on fixing my ballast? Need this one fixed... Help Help Help...

Quick added note... Power King ballast...

what i would do is i would go to pep boys and buy a wired fused and just wire it in and use car fuses for now on. it might cost 5 bucks. i have used them to wire up things on my boat.
