Does The RV Fuel Vault fit my Ford E-350 motorhome?

Yes. Precision-engineered for the Ford E-350 filler neck configuration. Use our Fitment Finder to confirm your exact year, make, model, and floorplan.

What is the difference between E-350 and E-450?

The E-350 is the lighter-duty chassis (GVWR under 14,050 lbs, typically for RVs under 26 feet). The E-450 is heavier duty for larger Class C models. The RV Fuel Vault fits both.

How long does installation take?

8-15 minutes with basic hand tools. No drilling, no cutting, completely reversible.

Does it cover gas or diesel?

Ford E-350 Class C RVs run on the 7.3L Godzilla V8 gas engine. The RV Fuel Vault covers the gas cap filler neck.

Limited Lifetime Warranty plus a 30-day satisfaction guarantee.
