Fuel pump insulators
Posted by HH56 On 2014/1/16 12:13:57
We've discussed the fuel pump heat insulators before but just curious what others have used to replace those missing pieces.
Since the engine and pump had been rebuilt and assembled many years ago, decided to change the pump innards to make sure it could handle modern gas. Imagine my surprise in removing the pump from the assembled engine to find properly wire tied yet smallish bolts in large holes. At least the phenolic washers and engine to pump phenolic insulator was there.
Have been looking at materials from McMaster to make insulators. Since pump is a vibrating item in a hot environment, wondering if impact strength or temperature should be the priority for the replacement. Of these, which would you choose or is there a better choice?
