Replacement Fuel Gas Tank Cap For Briggs & Stratton – Fits 799585 799684, Unbranded

Need a quick fix for a leaky or lost gas cap?

This unbranded replacement cap fits select Briggs & Stratton engines that take part numbers 799585 or 799684.

It’s a simple twist-on style with the ESCP feature—basically, it seals tight but still lets air in so your carb doesn’t vapor lock.

Not fancy, just functional.

No logo, no packaging hype.

If your mower, generator, or pressure washer has a cracked cap and you don’t want to pay dealer prices, give this one a shot.

Check your original part number first, then twist it on and get back to work.
