fuel pump update x15

[marek4792]

So I'm trying to get parts gathered to rebuild my fuel pump, replace the heads (Plunger and head is now one unit and non serviceable) and add the bleed line to the front pump head, but the part number for the new head 5572235 isn't coming up at my stealership, quickserve says it's obsolete. Original is 4384337 but doesn't show a succession for the new heads so I'm quite stumped. Trying to see if there's a new part number that I don't yet know of for the updated heads.
