I have an Edelbrock 1901 on mild 454 in a 71 corvette. Several years ago I install your quadrajet HP kit and applied recipe #2. While doing minor tuneup I noticed accerator pump sticks when the throttle throttle travel reaches the point where the pump should begin to collapse. So I need a new accelerator pump. But which one? There a 4 different lengths. The one that was installed was 2.625", I have several pumps out of Qjets I have around and they all are 2.53". Also do you sell individual gaskets.
Thanks
