Longchamp fuel tank

rachelianerachelianeMember
My LC was converted with LPG and I plan to return it running with gas. I just got the RH tank from previous owner, I can use it as a template to rebuild new one(s). It looks to be in aluminium because of the light weight. My questions are :
1- Does the resin I can see on the bottom section is a repair or is it stock ? (see pictures)
2- Is the yellow coating original?
3- If to rebuild the LH tank , would you make it aluminium, or rebuild both with Stainless steel?
4- Does anyone has cut or open such a tank to see how it is inside. I can see a wall from the inlet duct, I don't know where it stops. is it just to manage the flow when filling the tank?

Hi Racheliane,
my 74 Longchamp tanks were plain aluminium when I purchased the car. The only coating was black paint. Both tanks had pin hole corrosion so there was a permanent smell of fuel from the luggage compartment. They had been installed with something like carpet underfelt between the tank and the outer guard. Moisture in this felt had set up a corrosion cell to cause the pinholes.

To fix it I put an aluminium rivet into the largest holes. Then I coated the outside of the tank in an industrial grade clear 2 part epoxy. I also fixed the leaks that allowed moisture inside, and the car has been garaged ever since.

That repair was done more than 25 years ago, and has given no further problem.
Peter
