I not only have the bad accel pump but the 2GV on my 305 is not jetted right, I think it was meant for a '64 283...but I can vouch that the high-alcohol content fuel leave crystaline deposits and other damaging garbage in between the needle and seat as well as tearing cheap rubber. I "save" the old leather pump plungers in as many cases as I can.

I've seen people criticize the NAPA kits and praise the Autozone ones, but I had the opposite experience--the Autozone one (GP Sorenson) was 100% wrong in every way for the carb but I couldn't return it after opening it, which was required in order to find out everything was wrong! The NAPA Echlin kit had everything I needed and more, except for a float (didn't need anyway) and I went ahead and tried the rubber accel pump but as I expected it didn't work. I swapped the leather one back in but can't seem to "save" that one.

I'm not really meaning anything else in saying this except, don't swear off NAPA just because of the accel pump--that's not gonna improve anywhere else.
