they actually make a cover for the slot between the tanks. chrome ones, alum ones, etc. fuel injected tanks should have placement for the pump, which would be submersible. if i personally were changing tank, i would cut the section from around the petcock of both tanks and reuse the section from the savage tank on the hd tank.

Don't know why you would want to go to the trouble of cutting and welding just to keep the Suzi petc0ck. The Harley one works just like ours, is cheaper to replace if needed and the filter is easy to clean/cheap to replace. No muss, no fuss. If either part should go bad on the road there's a whole lot more Harley stores with parts in stock than there are Suzuki shops with 650 parts in stock. That last little issue is why I have an extra head gasket, brake pads and a used belt on hand. If I were to have to rely on a dealer within any range of my house for parts to keep me rolling I think I would be riding a Honda by now. If anything I drive or ride goes down I want it running again, preferably the same day. Suzuki can't even come close on that point with the Savage. And don't even get me started again on the jerkin' a$$ dealer in my town.

By the way, I'm still sittin' on my stock tank that I'll never use again. It's got the cap and a key but no pet-thang. No dents and a couple of minor scrswtches in the yellow that's not the 2000 color. It's from the '96 I think the year was. Cheap plus shipping so it doesn't sit and rust to death.
