Dr. Dan of Dr. Dan's Biodiesel takes us through the steps of curing a leaky injection pump in a Volkswagen TDI. Injection pumps on TDIs and older diesels are prone to leaks due to ultra-low-sulfur diesel fuel (ULSD) -- NOT due to biodiesel!! When a pump is introduced to ULSD and begins to leak, an infusion of biodiesel often works to seal it up again. Dan demonstrates the process of taking a 2000 Golf TDI ALH that is leaking ULSD and stopping the leak with B99.
