So, I pulled my fuel sending unit only to find it CAKED with "rust"... Is there a way to clean it and get conductance back into the strip of metal feeding the sending unit? I think I am going to commit to buying a new tank, but I am just unsure on what to do with the sending unit assembly...WCCC says a used unit is much better than a repro ($75 vs $30)...months ago I already bought new float, filter and gasket, so if there is a reliable way to repair my existing one, I would like to...or is it just better to buy one that is known to work?:confused:

HELP, please... Thank you!

Here are some images of this rusty mess:

Appears to be no electrical conductance:

I am no pro here, but that sending unit looks like toast to me. I'd cough up the $75 for a used original like Don recommended.

Good luck

I would replace that for sure hows the inside of the tank look? I know the sell some type of coating system for insides of tanks my dad used it on 77 mustang tank because they dont repop them yet. I used a repop unit and tank in my cougar never had a problem so far..But if you want to clean it look around on youtube I seen a guy cleaning parts in a tub of water with a scrap stainless trim as a conductor rod hooked to a batt charger not sure if it would work on that item like this.. then I seen a guy on t.v put a fender in a kiddie pool with some kinda maple syrup water mix looked like a new fender after 2 days of setting in it and its safe to pour drown the drain. youtube or google should come up with something

Stuck my finger in the tank and I could feel the rusty-scale on the inside...so that is why I was just going to buy a new one, figured trying to remove the scale and then coat it I would probably be close to the $100 for a new one (especially if I factored in my time)...hmmm

Thanks for the input so far, anyone else?

That sender is toast.

Yes, the repro's are not the greatest, but work fine. The only thing I did was encapsulate the inside of the terminal feedthrough with Ultra Black RTV for extra insurance, I have heard of them sometimes leaking. Hope this helps.

With the look of that sender I think I would replace tank, sender and all the lines up to the carb too!

Well, just talked with Lin and ordered a new tank and a repro sending unit. Hopefully they arrive by the weekend (I LOVE being so close to WCCC) and I can install them over the weekend. Thanks for the feedback, and thanks Bob - I will be sure to add a little RTV sealant to the terminal feed-through.

So a question on the "fuel tank" theme...

I know the tanks get crusty over time. Is there a recommended method to clean these up? Or are the repo's a good match, and better bet?
