just for the part numbers

Delco EP286
. At 12 volts, the operating pressure is 70-95 PSI with 36-40 gals per hour. The
biggest Delco pump is the
EP424
, which is 75-90 PSI at 40 gals per hour. EP 268 is a GM#
25117086, EP 424 is a GM# 25176156.

The factory Bosch pumps on any CIS or later VW also work fine.

It could be the ethanol, but to my knowledge they have been adding 10% ethanol to pump gas for years. One thing to try on older CIS or Digifant fuel pumps when they stop working is hook them up backwards and let them run in reverse for a few seconds. Sometimes the gears get jammed up with grit and wont turn. I made a jumper plug when I had my MK2 to do this. Every time my pump would quit, I crawled under it and just hooked it up in reverse and it freed itself. I eventually installed an MSD fuel pump but the jumper trick works sometimes.
