## Customer Reviews

### ⭐⭐⭐⭐⭐ It looks good
*by G***S on February 17, 2023*

It is always crap shoot when ordering on line. It is good when it arrives promptly, in one piece, is exactly what you interpreted it to be and looks like it is well made and the price was right. If it does not leak and holds up over time I will be a happy camper.As bonus it came with gloves,Teflon tape, hose clamps, brass nipples and plugs.

### ⭐⭐⭐⭐⭐ Fuel water seperator
*by T***M on March 16, 2022*

The most complete unit at Amazon. Includes all brass parts, teflon tape and hose clamps.

### ⭐⭐⭐⭐ Some items are poorly made and overtightened
*by R***P on July 13, 2022*

The filter and drain bowl assembly was over torqued. The water drain petcock rubber gasket popped of after 4hrs of runtime causing my fuel to empty out of the bowl and losing prime of the fuel hose. I tried to remove the bowl to reinstall the rubber gasket to reprime my fuel system offshore but couldn't remove the filter or bowl assembly. Ended up calling seatow for to tow the boat to shore.
