Dennis Detweiler Posted April 27, 2018 Report Share Posted April 27, 2018 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?

1949 Wraith Posted April 27, 2018 Report Share Posted April 27, 2018 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. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted April 27, 2018 Report Share Posted April 27, 2018 a heat shield works wonders...you need space on both side of the shield to be most effective..... Quote Link to comment Share on other sites More sharing options...
