On Knots2U's website under Cessna/337/interior they list a primer overhaul kit selling 50 cent o-rings for some 3 bucks apiece but the applicability description states in bold type "for non-fuel injected engines". I'd be willing to pay the premium for the correct parts but I called and asked about the discrepancy and could not receive confirmation that these are in fact correct. I've never been able to ascertain the proper part number for fuel resistant o-rings for this application. If anyone has the correct part number I'd very much appreciate knowing it. The mentioned "kit" uses MS29513-012 o-rings but I don't believe they have the proper cross-section. The primer seals appear smaller than standard.
