Biodiesel
Geoff, Just curious...had you run biodiesel through your pump before it began leaking? I've been doing some research on biodiesel's benefits over the ultra-low sulphur diesel when it comes to lubricating older pumps like ours. It seems that any diesel engine can run B20 biodiesel blend (20% ratio of bio to non-bio), but higher concentrations will effect natural and butyl rubber seals and could cause leakage in the fuel system components unless they were built (or rebuilt) with biodiesel in mind.
Anyhow...Just wondering if higher blends of biodiesel killed your pump.
Info on this from the National Boidiesel Board here.
