Greetings
I have a QJet carb on my 454 Mercruser I/O and my classic Pontiac 455 so have done some research on these. I have learned that you can not run the old school fuel pressure on these carbs with unleaded and oxygenated gas. The max fuel pressure for a marine Rochester Q Jet carb is 3.5#!! Please search Max fuel pressure for Rochester QJet carb or go to : https://video.search.yahoo.com/yhs/...=7927a1d462b461d24f505c9dcf8bc1f6&action=view
