WIF sensor (water in fuel) -- see the the connector next to the drain plug?

use some spray electrical cleaner and blow out the terminals, so the connector will snap back in

wouldn't hurt to remove the drain plug and spray some brake cleaner in there to help remove the crud buildup -- or better yet, remove the side cover and give the chamber a good cleaning

 

It goes about half on and then just doesn't move. You really think it's just cruddy terminals? I'll give that a try.

 

If you arn't the original owner the water in fuel sensor was a little finnicky to say the least. Once every few years I would remove it and hose it with brake/carb cleaner and it would clear a lot of gunk out. Seemed to be just a bad design in how crud built up and wouldn't settle/drain it would just build up. I didn't drain it often as after draining it 3-4 times a year it didn't seem to help so just every couple of years sprayed like 1/4 can of brake clean and all was good lol.

 

Yeah, I just bought it about a week and a half ago and am fixing things. Kind of a project. But I'll give that a shot and see if I can't get it to plug in. It really did NOT want to go in...hopefully cleaning helps.

 

That drain plug looks like its never seen visegrips.

If that sensor is grimy and the plug wont come out 'd replace that whole unit and start fresh.

 

Maybe the PO's answer to the water in fuel light was to just unplug the sensor. I'll see if I can get the plug out and drain it...good tip, Heavy_GD.

 

Took your guys' advice and cleaned connectors. It snapped back on. Took the opportunity to drain it while under too...seemed pretty normal, broke free ok with allen wrench. Edit: Dumped into glass jar and don't see any separation and idiot light isn't on when I start it. Guess I'm good.

 

If that drain plug is brass, it's not oem.... So the guy probably drained the separator more than once.
