## Questions & Answers

**Q: where are these made?**
A: CHINA.

**Q: Will itwork on the high-performance electric fuel pump**
A: This filter will have some flow issues with most high volume fuel pumps in either electric or mechanical versions. 

It is always very important to match your fuel filter flow volume to the output flow volume of your pumps rating.

**Q: Sirve para motores marinos de 2 tiempos?**
A: No, solamente 4 tiempos pq es para filtrar gasolina unicamente, 2 tiempos lleva aceite y el filtro no lo soporta.

A: Yes, as long as it has a 3/8" fuel hose...
