How To Solder A Gas Tank Repair | Soldering A Copper Patch | E30 Fuel Tank Repair & Repaint | 011
In this BMW E30 Project episode, I get around to repairing the leaky fuel tank and soldering a patch on the pinhole I found in it just above the filler neck in the last episode.
Here's what I use in this video:
Solder: ebay.us/6qAhEH
Soldering Flux: ebay.us/fhP5kP
Rotary tool: ebay.us/ZPSOCi
Rotary tool wire brushes: ebay.us/Gvv0zb
Parkside Angle Grinder: ebay.us/RUQyni
Epoxy Primer: ebay.us/GeNmxP
Sealey spray gun: ebay.us/1qe504
I initially thought I might be able to do a bit of a quick and easy bodge and simply put a self-tapping screw in the hole to plug it, however, I wire brushed the steel fuel tank again to find the hole was a lot larger than it initially looked.
This sadly ruled out any of my bodges and left me wondering how I could go about welding a patch onto the tank safely.
After a good bit of research I decided against JB Weld which was recommended to me, and went for a more traditional solder repair, soldering a copper patch onto the hole. It helped that I already had everything I needed to do that so didn't need to wait for JB Weld in the mail.
You often see these putty repairs recommended which are definitely only "semi-permanent" at best. I'm confident my solder repair as shown in this video is a life-long repair, and this tank is going to last me many years into the future now.
After the gas tank solder repair was done and dusted, I moved back to the original objective I had with this tank, and got it repainted and restored up to it's former glory.
I opted for silver instead of the original black colour for the fuel tank, and zinc nickel plated the hardware and fixings.
Leaky fuel tank holes are a common issue with steel BMW E30 fuel tanks at this point, and replacement gas tanks are getting more and more expensive as fewer are manufactured. So hopefully my experience with this will be helpful for others looking to save themselves some money.
