radiator cap for canton overflow tank?

[mustang_montana]

hey guys, ive had my canton overflow tank on for about a year now. ive been using this cheap cap i got at autozone, 18 lbs i think its leaking a little. im just wondering what psi i should be using for a cap, and maybe a p/n on a good one. thanks a lot

its a 96 gt with an 01 gt motor btw. thanks

I got an el cheapo cap when I ordered my Canton tank also. Mine was just a Moroso cap. It says 8-10lbs. on it. Worked perfectly for the 2 years I had it on. I got another cap that has a running pony on it. The place was vicsradiator.com but the website does'nt come up anymore so I guess maybe they went out of business.
