I'm in the midst of developing a way to correct the fuel starvation issue for my car. I was wondering if anyone knew for certain what the 1993 FD fuel tank is made of.
I am looking for any possible information: thickness, series number, coatings and experiences welding.

I have deduced that it is 16 Ga mild steel however I am not certain.

Any input?

 

Or you could just get into this GB:

I have one and I didn't like it.

 

i got one and i dont have a problem

 

It doesn't work with the A1000. But back on topic.

 

Think it may be 18 gauge aluminised under the sealant.....one was cut and shut locally here with a 100mm extension for a 24hr race in Germany....anyhoo, don't see the issue - get cuttin', start measurin'.

 

Said so like a sheet metal worker. Cut first ask questions later.
