I think the Dodge suffers from fuel vaporisation. The fuel pipes that run up the bulkhead to the changeover tap, then to the fuel pumps are, I think, suffering with the heat produced by the large exhaust manifold close by.

I'd like to insulate the pipes with some wrap-on material, but what a) is available and b) would look right on a 40s vehicle? I'm thinking of the stuff I've seen wrapped around exposed silencers on vintage racers, would that be suitable? The pipes run vertically and horizontally, so any lagging/insulation would need to be able to grip on ok.

thanks, R

This page has some interesting products

http://www.woolies-trim.co.uk/c-128-heat-deflection.aspx

The Thermo Shield Tape (bottom of that page) is described as being suitable to lag fuel pipes, but wouldn't look very nice under the Dodge's bonnet IMHO. I prefer the look of the exhaust wrap material, but that's designed to keep heat in, rather than reflect it back which is what I need .. if I could find some white-coloured Thermo Shield Tape then I'd go with that, but if nothing else turns up I'll have to go with silver (which would be most efficient I suppose, but wouldn't look very nice...)

Lagging the manifold would be too tricky, plus I don't want that getting any hotter than it has to either.

Old type lagging was usually asbestos based and as such is obviously unobtainable.
However, most inboard engine canal boats have exhausts lagged with the accepable alternative which looks much the same.
If that fits the bill,it should be readily available from boat yards or chandlers.
I have used it on my Gentry.
Jim.

Hi Rick,

Hide an electric pump at the rear so that fuel pushed through rather than sucked.
