You'll have to do something similar to stock, other wise the check engine light will come on. I believe the ecm monitors pump amperage and will throw a code if it's out of spec.
Various manufacturers have an updated version. The original pump was a vane pump that wasn't really designed to pull fuel long distances like they had it installed. The update is an inline pump that is a bolt in place option.
Look up delphi # hfp953 for the updated version. Carter and airtex also make a version of this as well.
As far as fass or other aftermarket companies go, I've never used them in commercial service, so I can't tell you how well they'd work.
Be sure to replace the fuel filter and water seperator when replacing the fuel pump
The original vane style pump is still available. If you're feeling ambitious, I know guys that have made a harness extension and relocated that pump back near the water seperator with good results.
