Another lister mentioned his fuel pump rebuild kit from Moss had some
rubber bits that reacted to the gasoline he was using.
Last week, I pulled out my '62 TR4 for a drive and was looking under the
hood as it idled after checking the fluids, and noticed I had a pretty
good leak coming from the fuel pump. I'm guessing the diaphram ruptured.
What makes this mildly irritating was this pump was rebuild with a Moss
kit a couple of years ago. It worked faultlessly until last weekend.
My guess is that the kit either:
1. Was constructed from sub-standard rubber components
2. Reacted to a new formulation of gasoline
3. Has been reacting with modern formulations of gasoline since the day it
was installed.
One of the Moss guys wrote an article for 'British Motoring' a few years
back about the effects of new gasoline additives on the various rubber
components of older cars. This could indeed be the cause.
If so, then I suspect we'll see on-going fuel delivery problems until the
rubber bits are constructed from new materials.
