That looks like a battery problem . Theses pumps are indestructible . Almost. If the pump fails it will be all out. What voltage are you reading from battery ? Go pick up meter from harbor freight for 10 bucks . Free with coupon .

Besides checking the battery voltage, if its been used a few times. Take the upper half of the pump out by pressing the red tab and turning the body of the pump 1/2 turn counter clock wise. Once you have it appart check to see if there's eel grass on the shaft. I had that happen, the impeller looked good but the shaft had a bunch and it was not visible with the pump assembled. The resistance on the shaft slowed it down.

I try to break the pump down every trip so I don't have any surprises . Top is quick release .

You don't have a good suction, there is a leak somewhere. Try some GOOP on the connection between the intake and the tank. Also, you do know these pumps are rated for 12V, so you can always try that. Or get a new pump, they're cheap. Or return the tank for another one.

Faulty suction could explain a bit. If there is air in the pump it will be noisy and pump very slowly like you have pictured.


Make sure the pump is put back together correctly and you pedal faster a little longer. It will completely fill the pump. Make sure your battery is fully charged.
