Oiwa Garage Tech Note

"A cap that does not seal lets condensation into the tank, which is how these trucks grow rust and clog the fuel filter. A proper seal matters."

Frequently Asked Questions

Will this seal my tank properly?

Yes - it is the factory-style cap for the Acty filler neck. Fit it and turn until it clicks, and it seals like the original.

How do I know my gas cap is not sealing?

If the cap will not click or hold, or you get condensation and rust in the tank and a clogging fuel filter, the seal has failed. A proper seal keeps water out of the tank.

Does this fit the Acty Van?

Yes - the Honda Acty Van HH3, HH4 (1990-1999) uses the same cap. We list the van version separately so you can confirm fitment against your chassis code. After something with more style? The crown gas cap fits the same filler.
