Fuel pumps.

Can anyone tell me the specs [flow rate and output pressure] for the in-tank TPI fuel pump? If not - how about the make/model etc so that I can look it up.
Thanks.

Aus,

The TPI system pump should be able to develop at minimum 60 PSIG (413 KPa) with a closed discharge line. Don't operate the pump in this mode any longer than is necessary to test the pressure.

The minimum flow should be one pint (475 cc) in fifteen seconds to an open container.

The original pump is an AC/Delco, but I don't have the part number at hand, sorry.
