You kit came with 2 cups? What did your original accelerator pump look like?
That cup you show does not take a spring inside the cup to spread the lip.
Per Cliff's studies, even the blue cups coming in kits swell with ethanol.
I've got the same problem with the QJ on the ranch truck. Plan on getting one of these.
