hey guys been on the hunt for a fuel sending unit for a 72 d200 single cab with fuel tank in cab. anywhere i can buy or anything compatible with the original unit. its a big block 400 6.6 liter if that helps. thanks guys.

 

Idk what your vehicle is really but i went to the link below to buy a sending unit for my 64 imperial i thought i was going to have a hard time getting it but they had it in stock. They shipped pretty quick too! they even have a gas tank and the straps for my imperial which i'm surprised at also cant find parts for my imperial so this is a nice site to have around.

you also might want to look and see some of the cars common models share the same parts with rare models. such as gas tanks for the uncommon models. example a chrysler 300 a common model might share the same tank as a imperial a rare model, but its only listed under the 300 and not the imperial even though its the same part. do a little google search see if your truck shares parts with other vehicles.

You can also give these guys a call they literally have everything for all truck models except the 66 apache trucks i think it was they skipped that year I would call there will be stuff that they sell that's not in the catalog
