## Questions & Answers

**Q: Can i use this on a 99 nissan maxima?**
A: For windshield washer - yes. Not for fuel system. Your car is fuel injectected and fuel system is operaiting under much higher pressure then this pump can handle.

**Q: Can this be used to start a continuous siphon (assuming gravity is in your favor) or does it require hand pumping the whole time?**
A: I have not used it in such a manner, I would think it would work once the flow is started. The check valve in the unit is supposed to provide a force flow to the unit, then the fuel pump would take over, or gravity flow if that is the manner of fuel flow. Hope this helps.

**Q: is the internal valve spring loaded?are you SURE? just bought one that does not work**
A: Yes the valve is internally try to close one side and press the bulb .... vacuum your hand?

**Q: My hose says 5/16” ID. Would this 8mm barb fit?**
A: My husband says it should.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great primer bulb
*by L***S on May 16, 2025*

Works as expected, will harden over time, lasted many years. Ethanol is murder, pleased the the quality of the bulb.

### ⭐⭐⭐⭐⭐ Not high quality rubber
*by C***K on October 5, 2025*

Can’t recommend because the rubber bulb has rotted and cracked after just a few years!

### ⭐⭐⭐⭐ Works as shown
*by K***T on March 2, 2024*

It is a standard squeeze bulb with two different sized fittings. It does not include a check valve to specify the direction of flow. Therefore, when trying to "pull" on a siphon, when one squeezes the bulb, one is also "pushing" the siphon back up the tube, unless you include other parts to prevent same.
