Replacement Afordable fuel injection fuel pump part number

I bought my AFI kit second had from this forum and lately the fuel pump mounted on the fram rail is becomming louder and serging. The kit is a TBI. This is making my volt gauge dance like I have a huge stero system installed. Any one know the part number or source for the replacement pump. I know I can contact them but I would like a local replacement source. I've looked at the pump and their are no numbers that I can see. Thanks for the help. JC

Airtex makes a good external pump. Part#E8228 I'm using this one in my 5.0 EFI build.

Humm looks a lot like what I've got installed. I wonder if an efi rated pump would flow more fuel than I need and give me a rich condition . I think my pump runs about 30 lbs of pressure?

Your TBI is EFI. You'll be fine using that pump as long as your pressure regulator is doing its job, which it probably is if it has been running so far.

Another option is the E2000 which was used on late 80s/early 90s F150s and Broncos.
