Quality and correctly sized
Nice construction, used for pond water feature rather than fuel so s tad over engineered for the purpose but I like that. Good fit well made.

Pesimo
Pesima calidad, no es de la medida que describe (mas chica) y no soporta mas de 5 psi de presión, no lo puedo devolver porque ya lo use!

Works as intended.
My zero turn would crank a little longer than I thought it should before it would start. I suspected the fuel was siphoning back to the tank after shutdown. This was cheap and easy to install so why not give it a try. Glad I did. Much better now.
