What is this light?

Any port in a storm....... at least I never got any tatoo's with my beer goggles on....

Nether did I. Fashionable or not, I still won't get one. I think they look dumber than ****, especially on women. About as classy and tasteful as graffiti.

Back off the water drain from the filter until it lets it out.. do that for a bit until you smell good fresh fuel. Also would unplug the sensor at the but connection to the harness and be sure theres no build up inside

I removed 10mm plug at the top of the fuel filter housing and gave a few pumps of the primer on top. Fuel came out and it looked fine. Shouldn't there be something at the bottom of the filter since water is heaver than fuel? I unplugged the sensor but didn't see an obvious way to get the sensor off the bottom of the fuel filter.

The water sensor on the bottom of the filter is also the drain.......... unplug the sensor then unscrew it until fuel starts coming out

Thanks Navasot. That was exactly what it was. The sensor on the bottom looks nothing like it should turn and any twisting action would cause it to break right off.

I'm running the red dyed farm diesel so it was really easy to see the clear water change to the red diesel.

I don't know about your model but on my 1538 there are two fuel filters. The prefilter has a replaceable paper element and it is the low point in the fuel system. The final twist on filter is where the moisture sensor is and it's much higher up in the fuel line so if you have water there, then the lower pre filter is likely full of water. The prefilter does have a 10mm drain plug just off center on the bottom of the canister. However if I ever found water in it, I'd replace the paper element so it didn't turn into paper mache and clog up my fuel system.

the upper filter is were the water is caught and drained which in return cuts the light off .... but very valid point since there was indeed water running through it... think its $11 filter anyway

Looks like I only have the 1 spin on bosch filter.

Right but you have a canister element filter in the system as well. you have to take the bolt off and slide the can down then pull the filter out of the can.

Yeah the bottom element is a cheap paper affair. It looks like someone rolled up some scrap cardboard. My guess is that if the upper filter had any water in it the bottom element is saturated and ruined. I think they should put a regular sediment bowl and drain down there at the low point where you could see and drain water before it makes it's way any further in the fuel system. The so called moisture sensor is placed where it reports problems after the fact. It needs to be moved to the lower filter where it would do more good. The sensor is just two pins spaced about 0.10" apart so it's nothing exotic.
