I have a Chrysler 360 in my boat and to be honest with you, you and I have very rare set ups. Check out my website there is a whole page on the motor build alone. <br /> You can always try ...... HERE! http://www.iboats.com/mall/index.cgi?prod_id=41960 <br />I wouldn't rebuild it. Its not worth the hassle. That pump has been in there for more then 30 years. Not only is the diaphragm bad but I bet the whole thing is worn out. For as cheap as they are there is no reason not to replace it. <br /> PS you didn't here it from me but the same fuel pump only cost 30 bucks at Pep Boys. I have compared both (original to the Pep Boys one) and there is no difference then the ones you get at the marine stores.
I found a "automotive" pump for $20 at AUTOZONE. I think that's what I'll go with. My motor is in a 1962 Chris Craft Sea Skiff which I'm bringing back to life.
