Reply to "Fuel Leak..........."

George PAdmin.

Ron, welcome to the 4300D. That carb and I have a long frustrating history with each other, dating back to the 1970s and extending into the 1990s.

My advice, eliminate the fuel leak for now (are you guys sure JB Weld wouldn't work?).

But as a permanent solution, and to achieve superior engineering and performance, I'll ask you to consider a 1970/1971 vintage factory manifold (casting number D0AE-9425-L) and a 750 cfm Holley 4150 style replacement carburetor having these features:

(1) annular booster venturis
(2) electric choke
(3) vacuum secondaries
(4) "street-performance" calibration
(5) well designed high-capacity fuel bowls
(6) ease of calibration when needed

Summit Racing's 750 cfm carburetor meets all of that criteria. Its reasonably priced, and folks have had good experience with it. I consider it the most cost effective replacement for the 4300D (which was also rated at 750 cfm).
