Replacement stock-type fuel tank for restoring your CB400F's frame to a complete, ride-ready condition. Comes in primer grey straight out of the box, ready for you to finish in your colour of choice — ideal for a full restoration where you're matching a specific paint scheme or want a fresh, custom finish on an otherwise stock build.
Requires a 14mm x 1.0 threaded nut petcock — our part #12-0078 is confirmed to work. Note that this tank does not accept a stock-type petcock. Gas cap (#20-0045), petcock, emblems, and all other hardware are not included and will need to be sourced separately.

Frequently Asked Questions
Which petcock fits the 1975-1976 Honda CB400F replacement tank?
The tank requires a 14 x 1.0 nut-type petcock, such as part 12-0078. The original stock CB400F petcock does not fit this replacement tank.
What is included with the primer-gray CB400F tank?
One primer-gray fuel tank is included. The gas cap, 14 x 1.0 petcock, emblems and mounting hardware are not included.
What should be done before painting and filling the replacement tank?
Test-fit the front cushions, rear mount, petcock and cap before final paint. Rinse and leak-test the tank, keep debris out of the fuel outlet and inspect all connections after adding fuel.
