Default HELP, fuel pump sending unit

First off, new to this forum. Just picked up a 1993 Nissan d21 4x4 v6. The truck has a 21 gallon tank that is rusted on the inside due to sitting for years. All I can find is the 15 gallon tank, but I am unsure of what fuel pump sending unit I will need. Only ones I have found are for years 88-92. Any help will be appreciated.

POR15 makes a full kit to restore the tank for $100. Buy 5 gallons of Evaporust to remove all the rust then clean and seal it with the POR15. NPD sells the POR kits. You can order 5 gallons of Evaporust at Northern Tool.

The 21 gallon tank is hard to find. Scrap yards are required to puncture fuel tanks for insurance liability reasons.

The fuel pump sending units were not very different. Older ones had the dual fuel gauge. Seems like the newest ones have an extra sensor wire.

Thanks for the info, the only sending unit I can find is for years 1988-1992. The 1992 looks just like the one i pulled out of my 1993 though.

Does anyone know if the spectra fuel pump assembly will fit a 93 d21?

I don't know, but if you buy the part, make sure you get it from someplace like Amazon that accepts returns if it doesn't work.

How much do they puncture them?

The ones I've seen have holes in them that are about 1" in diameter, give or take. I think a patch could be welded over it fairly easily. Weirdly enough there is a yard near me that actually removes the tanks and fuel pumps, leaving them intact. First time I'd ever seen that.
