The stand pipes are pretty much the same as the dummy plug as far as blowing.
The new update for the stand pipe also has the nylon ring to help with the o-ring
problem, but it also has the updated check valve also witch is another thing that helps with that noise from the pump. For any questions give me a call at (678) 920-1187.
Signs that this could be a problem are:
- Hot no start
- No star
