I believe that when these pumps are spec'd they're intentioned for the vertical sending unit that has no diameter restrictions regarding the mount. It might be interesting if someone has an old tank unit and they could measure the ID of the sleeves. The only one I have is new and assembled and I can't get a vernier caliper in there to accurately say yes or no but it looks like it could be a challenge.

You can't assume any longer that Delphi implies GM or NOT and they might very well do a GM pump to different specs but the Delphi pump replacement for the GM 25163473 (FE0114) is spec'd at 425 kPa (61.64 PSI) application pressure and 500 - 750 kPa (72.5 - 108.7 PSI) relief pressure. The only flow rate mentioned is 27 with no mention of unit of measure. It's also maybe a little 'chubby' at 36.7mm. It's applications are all for the vertical standing senders also.

Found this from a cross reference guide. No specs on flow rates.
