Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It is typically welded onto the tank and features a bolt-hole pattern conforming to TTMA recommended practices, so it mates with standard sump fittings. The flange prevents leaks and maintains tank integrity when a sump is not needed. It is commonly replaced if damaged, corroded, or when reconfiguring tank plumbing.
