It has been a long time since we have taken advantage of our blog and actually posted something note worthy. Well today is the day we start to change all that. We had the opportunity to work with Zosh, A local Honda enthusiast to our area and YouTube Content creater who puts out a lot of great content working with friends and Honda’s. We offered up our B-Series fuel line tuck kit for a honest review to be installed on his dc2 Integra with a B20Vtec and Zosh was more than happy to give it a go. What we got was more like a install guide but it was up to him what he wanted to do with it. We have attached the Vlog for your viewing pleasure. Enjoy.

These fittings will work for any b-series motor which has the black box on the back of the block. It just gives you another port to hook up a catch can. This fitting will come in real handy to those who only want to use one port on the back of the block. You don’t have to take off the stock 28mm plug on the back of the block, which can be tough if the motor is still in the car.

Note: B20 blocks don’t have this port.
