Vented Fill Cap with 2-inch Base by Fill-Rite FRTCB Review

This gas cap is well designed and immaculately finished. Works as intended. Durable and easy to close. If you don't know how to install it, ask someone who does. Remember! Your work with combustible fuels. I am happy with this purchase.

Works great as an overflow tank vent. This cap doesn't hold the pressure, I filled my tank full of diesel and some of it spilled while parked on a hill. Now I know not to fill the tank closer than an inch to the brim. Good price

Works as it should. Some people say it leaks and I have to wonder if it's because they close it before the first step. Not sure why it's there, but there is a first notch that doesn't close tight enough. Twist it another quarter turn and it won't leak.

Almost standard filler cap that fits over the top of a fuel drum. Without blocking. The lid has a moisture seal and is spring-loaded, so while it relieves pressure, it doesn't let in as much moisture as a lid without a seal. The threads are acceptable, but not the cleanest I've seen. So expect to use sealant when installing. Seems a reasonable price for what you get.

The vent is designed for very heavy duty applications and has nice features like a one piece molded body with a stainless steel cover that can be locked with a padlock. Made in the USA in Indiana with a quality and weight you won't typically find anywhere else. I put them on all my fuel tanks. The seller was also very quick with the delivery and I think the price was pretty good, especially given the high quality of the product.
