Heat shield saga continued!

Following my previous post, where I crowed about having 'invented' a heat shield for the carb (only to discover that Grumpy made one commercially), I have just finished another mod to protect the petrol pipe from exhaust heat. This is a short strip of woven fibreglass insulation with aluminium facing about 50mm wide and 300mm in length. It is specifically made for this sort of purpose and is commercially available. I bought a 50m roll of it!

The strip is folded at the top and riveted to make a pocket to slip over the pipe retaining strip. Clips are used to secure it in position and also at the bottom on the body joint. A photo of the installation is attached:[frame]Image[/frame]

Looks good. What are you planning to do w/the other 49.7m of material left over?

Personally having that length of insulation tape in your possession I would have thought it prudent to insulated the pump uplift pipe right up to and including the petrol pump union.

Mmmm...might find a use for it, somewhere! Sounds a good idea to wrap the exhaust pipe in it.

Took the car for a spin today down on the Levels for a picnic (v. hot) and was going steadily along and it started to stutter. Have now changed the coil in line with a suggestion that it was breaking down when the car got hot. We'll see if that does the trick tomorrow. Going for another picnic...

I really can't say, but it seems unlikely it was lack of shielding. I just wonder whether there's a bit of fuel contamination, like water entering the carb, for instance. The moggie is garaged and kept dry in normal circumstances, but I just wonder if water got in when I washed it recently. The tank is in perfect condition and was replaced a few years ago. The fuel pump seems to be behaving quite normally and just ticks gently (can't hear it in the car, though). I replaced the points with a double-headed set to lessen the chance of failure.

Anyway, we're off on a picnic today and so I hope not to break down! It won't be the coil, though, as that was replaced yesterday.

It's NEVER the coil - put the old one back on...... 'breaking down when hot' - aye right.... :roll:

Reasonable looking heat shield kit from ESM for £22.50 = Vat.
Anybody fitted one of these....?
