Ive returned one unit of the FS store already for faulty wiring.
1) Also,There is a note taped to every FS box that ships out to test the float before final install. . The reason for this is as previously mentioned it will likely hang up on the internal plastic tank baffle as it drops down and typically never show any lower than half a tank. You can accomplish this test by attaching a fishing wire to the tank float rod and installing it inside the tank without the oring, pulling on the wire to cycle the float thru its range of motion, and see if it freely shows 0-90 ohms. If it hangs up, the note says to bend the resistor bracket.. although I bent the float rod itself. I had to do this for both units I received.
2) The quality seems to vary with these units, the second unit I received had a more secure pump ground wire screwed to the unit instead of brazed. This was the failure point of my first unit.
3) If you compare an OEM unit to a FS unit, you will see that the OEM float is a little bit more inset, preventing any interference with the tank baffle. I don't know why FS can't make these adjustments so you don't have to do any bending, maybe this unit is used on other types of cars and is more universal.
4) Minor quibble but the FS metal vent line points downwards whereas the OEM points upwards, because of this I had to lengthen my rubber vent hose with a coupler and some more hose.
5) Having experienced these issues, I wouldn't recommend FS store for this particular car part. That being said I have been pleased with all their other products and they are very responsive and understanding when I have questions.
