Highly satisfied

Everything works as advertised, upgraded From a single 525 to dual 340lph plenty of room to grow, product arrived in a timely manner, everything appeared to be super high quality, will definitely be reaching out to quantum for any future projects that require a superior fueling system

Wrong pump

I've had good experiences with your company, but this pump was not suitable for the application that I ordered it for and I definitely would love to return it.

Doesn't fit.

Basically it's too long. Not enough space for nipple on top to be put onto the other nipple on fuel pump. Also The orientation direction of the sock is backwards. Do a 180 onthe sock and it'll be better. Other then that. Get some better plastic material so it doesn't break so easily. I just ordered another one becuz the plastic was so cheap.
