Going thru list of things to do to car and replacing all o-rings is part of it. Thinking about fact that I will have some nitro in it at times anw ondering if I should just go with EPDM. Works with both nitro and alky, just don't like any thing petroleum . Harder to keep system lubed when you can't add wd 40 or other lubes. Then again would 20 to 30% load hurt Buna n o-rings?
What are running with limited loads of nitro?
