When winterizing my 302 today, I found a fuel leak. I pulled the carb and found the accelerator pump diaphragm in real bad shape. Has anyone gone to the alcohol diaphragm instead of the standard black rubber one? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Not me I'm keeping mine original. Actually the last one I installed is a light green diaphragm maybe since you did yours Holley changed them? ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Gary, I've never rebuilt the carb and don't know if a PO ever has. The engine runs great but since I pulled the carb, I might as well do a rebuild on it over winter. Summit has two diaphragms available. The regular black one and a blue/green that's listed as "alcohol" hence the question. I'm assuming they mean it's good for ethanol. I'll know more about the condition of other internal rubber parts once I open it up. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I wonder if the marine kits come with "alcohol" diaphragm because that's what came in my kit ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

I have the green one that skidim sells: http://www.skidim.com/Holley-Parts/products/1055/" rel="nofollow - http://www.skidim.com/Holley-Parts/products/1055/ They say it's compatible with alcohol based fuels. I was just in there this past weekend. I had to swap out the fuel bowl, because one of the accelerator pump-diaghram-cover-screw-holes [that's a mouthful  ) in the bowl was stripped out.I wound up putting the green skidim acc pump diaphragm back. It was still in great shape after 3 summers. |
