I think I am having a vapor lock problem on my '96 Mercruiser 2bbl 5.7L. It has the steel fuel lines running from the water seperator and fuel pump to the carb. I got 1/4" NPT male to 3/8" barb fittings for the fuel pump and water sep., but what do I do for the carb? It has a fitting that contains a fuel filter/screen with a lip for the flare fitting. Can I replace that with something else, or do I have to have a nipple of steel tubing to clamp the rubber tubing to? Any help would be greatly appreciated.<br /><br />Thanks<br />Chris
