dropped the tank on my '82 burban as the 'water in fuel' light keeps going on and it's been sitting some time, best to see what's going on and clean it out.

I spend my time trying to find a matching fuel sending unit and turning up a lot of nada. I know being a first year there were things changed and improved so I need some knowledge (part numbers would be very shiny indeed)

Here is the unit, taken best I could one handedly. 4 outlets, two electrical buttons and a blade. my googling has turned up nothing quite like it.

If you search RockAuto and pull up an 82 C20 pickup they list Spectra Sending units that look just like what your pic has.

they do. but there are only 3 tubes, not 4. Rockauto was my first try to find it as their parts are well sorted. thanks though.

To my knowledge, nobody reproduces the 1982 only " water in fuel" sensor unit. I've also never seen a 4-line unit as well. mine being a single tank is 3-line. i usually just rebuild my sending units and put new diesel socks on them.

The later models didn't have water in the fuel sensor, I can't remember i know it was "Glow plugs" and something else As mentioned 1982-83 only had the "Fuel Siphon" Valves on the Inside of the spring hangers. Use it and get some suction maybe you do have water in your lines. Otherwise, try this video.

seen that video before, found no such things under the suburban. so we dropped the tank. we'd gotten it like 96% empty siphoning from the filler neck so not so bad. a bit of dirt/dust from sitting so long.

Oooh gotcha. I never knew burbs never had that feature... Maybe only the trucks. Hmm.

Well at least you did. If you need to keep the water in fuel thing possibly solder it onto a newer unit and run your wires up where ever they go or something. Because most people I know don't even mess with it because the fact they are "Hens teeth" to find & Discontinued etc.

The 6.5L fuel filter manager has a water in fuel sensor on the side.
You can swap out your square filter for the newer 6.5L filter and utilize that sensor instead of the tank

the old one has at some point been changed to the round spin-on dude, but good to know we can relocate the sensor there.

The square canisters also had a WIF sensor if memory serves. My 86 has the light at least.

yeah no real idea there, as with any used vehicle you have to start trying to decode whats been done over the years to it.

Interesting never knew. I'll have to verify with a friend of mine. If it does I wouldn't think it has the dash light I know for a fact that was only 2 yrs on the early models.

me personally maybe 1 from playing musical vehicles. the guy before me drove it like 6-8 months and then parked it for a decade and change and I think before him was the original dude
it very well could be the original unit.
ODO says 210,486

i've been doing a build log of getting it the TLC its needed on a chevy specific forum, but came here as this is more a diesel thing and not gotten many bites on my questions specific to the fuel system stuff, but good knowledge on the squarebody stuff.
