The fuel pump I picked up was AcDelco Part# EP-381 it has 65 psi? I was told it would fit right into the s10 sender, but I don't think they knew about s10's that were '96 or newer.

Thanks for all the answers. I'm glad this many people look at the LSx swap section everyday. I think I'll scour the junkyards looking for a fuel sender from a '95 or older s10 tomorrow.
