Fuel Tank Too Near Exhaust Pipe?


Dennis Detweiler

Recommended Posts

I'm installing a new poly fuel tank in my 39. The car has a split manifold and custom welded dual exhaust. The pipes have a steel rod welded between them before they bend around the tank, so I can't separate them any farther apart.  The new tank has 1 inch of clearance from the pipes on each side. Too close? Should I fabricate a heat shield on each side of the tank? Or, cut the rod and spread the pipes apart a little more? Or, is 1 inch clearance enough?

My '38 Dodge has a poly tank and when I went to a split exhaust, both pipes are run on the right side making a smaller clearance with the tank. Probably not needed, but I put a stainless heat shield on that side of the tank. Peace of mind.
