Got new fuel sending unit, what else do I need?

I just received my ACDelco fuel sending unit (expensive little sucker) and a Walbro GSS340 255 lph fuel pump. There are some pieces that I need to finish up attaching everything, and I'd like to hear what brands or locations you buy these from.
  • Fuel Strainer - Will the factory strainer fit a walbro GSS series pump? What is a good brand to get?
  • Adaptor from factory harness to GSS style connector. Not sure where to get these, anyone have a link?
As far as connecting the pump outlet to the sending unit, should I just use rubber hose with clamps? What about the four lines? It looks like three will use rubber hose with clamps and the last will screw in? Is there anything unexpected that I might not be thinking about that I'll have to buy?

After much searching I think I found the proper install kit for the pump. Does this look right? http://www.racetronix.biz/itemdesc.asp?ic=PIK-003&Tp=

So I got just the regular GSS340 and not the GSS340M, will this kit still work? I've seen a lot of threads mention the 340M but I've also seen some with the 340 .

Re: Got new fuel sending unit, what else do I need?

Following up on what I put above, I did get the kit that I linked to. Looks like it will work fine. Had to swap the wires on the adapter but was not hard to do, just have to stick a jewelers screwdriver in the end and pull them out. As for the filter sock, it doesn't fit on the pump since it's not the 340M. I may bring it in to a local machine shop and have them take a tiny bit off so that it's equivalent to a 340M, or would you recommend just trying to find a filter sock that fits the unmodified 340?
