Address common customer concerns.
Q1: Why is my manual primer pump leaking fuel from the top?
A: This is usually due to aged or cracked internal seals. Since these pumps are sealed units, the most reliable and cost-effective solution is to replace the entire assembly (5001821529).
Q2: Does the pump come with the sealing O-ring?
A: Yes, our package includes the necessary high-temperature resistant O-ring to ensure a vacuum-tight seal upon installation.
Q3: How do I know when the priming is complete?
A: Press the pump repeatedly until you feel significant resistance. This indicates that the fuel lines are filled and the air has been purged back to the tank.
Q4: Do you offer a warranty on this part?
A: Absolutely. We provide a 12-month warranty against manufacturing defects to give you peace of mind on the road.
