It's me who needs the pump. I run an internal Armstrong pump and bring on the bosch pump with a hobbs switch. Well my bosch pump started failing yesterday(would only pump about 20 psi) and I was looking for another one. This is what I found out. The Bosch 204 came in Volkswagon from 77 thry 88 and Audi's 77 thru 86. You can buy these retail for 80.00$. A buddy of mine got one thru Carquest for 110.00 and I'll have it Friday....I hope this will help people in the future who are looking for external pumps. 110.00$ sure beats the hell out of paying 250.oo or more for an Areomotive or Walbro stand alone pump, and since I getting the same pump again, I don't have to make any plumbing changes. It will drop right in where I had the other one...Thanks for the replys....Dwayne Thompson
