At the risk of stating the obvious, in addition to the pick-up 'Christmas tree' falling off, some other possibilities come to mind:
- Sending unit is off. One of the PO's might have changed it and installed what was on the shelf versus the correct part.
- Tank is smaller than spec. Might have come as custom order, or a PO might have done it.
- Not getting a complete fill due to the OE setup which causes a *lot* of foam.
- Combination of the above.
One way to test for total capacity is to make absolutely sure the fill was complete by dribbling fuel until there is no more foam at the filler neck and it is just fuel. Then drive until fuel level gets to the point where you would normally fill, and instead drain anything leftover. If what comes out is nominal, then the tank is smaller than usual. If another ~5 gallons comes out, focus is on the pick-up and / or sending unit.
Alternatively, just drop the tank and do the in-tank mods and fix whatever else needs addressing. If the tank does turn out that it is smaller than normal by way of a part number review, you are half way through installing a correct / larger sized one
