[Vwdiesel] Tdi Pump Seepage w/ Biodiesel?

[dieseltdi at verizon.net]

Ed, the seal is available aftermarket (all over ebay) and pretty  
easily replaced if you are careful.  Unfortunately you will have to  
buy a complete gasket set for the pump just to get the seal you need.   
You will also need to either get the special tool necessary to  loosen  
the funny shaped nut on the front left of the pump or do what I did:   
Use a dremel tool to cut a nice slot for a large slotted screw  
driver.  Hayden

"Dictatorships all have common factors:  a government controlled by  
one party, a leader who claims to have special powers outside the law  
to keep the country "safe", secret prisons where people are locked up  
without charges or trial and government opponents are branded as  
unpatriotic and charged with aiding the enemy."
