SS Fuel Tank??

[Anonymous]

Hi All

A friend of mine wants to make a new fuel tank for a 69 coupe using stainless steel.

I think is dangerous to do that and I have few questions.

1 Can you do that?
2 Is it dangerous?
3 If 1=YES 2=NO what SS thickness would be good?
4 Does it matter if the wall of the tank are smooth? (No ripples)
5 Can the tank be just rectangular? (No cut at the back end)
6 If the tank is rectangular this will not affect fuel flow? (i.e. it has to be a reason why fuel tanks have ripples, mostly are rounded, and have some kind of cut at one side)

Thanks
Vas

8) 1: yes
2: depends
3: minimum 16 gauge
4: no
5: yes
6: no

for #2, if your friend is a good welder, then ss is no problem. another option would be to install a fuel bladder in a stainless steel shell.

#6 the reason for the "ripples" it because the tank is also the trunk floor, and since the factory used very thin gauge metal, they were put there for rigidity. as for the rounding of the corners, two reasons;
1: ease of production
2: easier to use the full capacity of the tank.

Replacemnet tanks are angled at the rear if needed, to ensure that the back does not lie outside the plane created by placing a flat surface from the rear tyres to the lowest part of the body. That way, if the rear drags, the tank is unhurt.

Plenty of baffles will help combat fuel starvation.

An access panel large enough to change out an in-tank pump is a good idea. Use an aftermarket fuel level sender (like VDO) and make a pickup tube to suit the tank and pump system.
