I used this on my 90 Chevy when I went to ram assist. It kept overflowing through the cap, so i added this piece of hose to the top of it. It didnt leak at all around the resivior or overflow anymore. I did have to heat it up a little to get it over the resivior. I also cut the top off of another resivior and put it in the top, so it vents properly with a standard cap. $20 shipped or make me an offer. Am full hydro now so i dont need it anymore. Paypal. Thanks
