I just bought some stuff from them the other day. I got my stuff and most of it is currently on the truck. I haven't got the gas sender float on yet, but give me time...
I usually call them if I'm wondering about a part; it seems to be the fastest. They do eventually get back to you via email if you ask questions that way, though.
They're also having a sale right now for orders from their online store. FYI.
