Holley throttle pump daphram
 
Hi all I have a new Holley 600 . been on my engine about 6 months . not used it much . Still waiting for IVA . my question is the pump diaphragm has been leaking . I replaced it yesterday and its still leaking . Should I put a sealant on it ? I know it came without sealant . I will get in touch with real steel tomorrow
that's who I got the carb from .

Thanks John..

No sealant reqd, check the pump cover is not distorted, warped, sheet of sandpaper on some flat glass or newish oilstone to get it flat, check the carb bowl surface for same and porosity in that area, probably over tightened by someone if its warped.
