[Vwdiesel] More Quantum Questions?

[William J Toensing]

Well, no more right now but I am sure more will follow. What follows will be a progress report & report of an interesting phone conversion I had.
I bought a used Quantum IP on eBay for $150 & had him forward it to a repair person in Maryland whom I shall not name yet, for rebuilding, since I have not received the pump yet. However, if my gut feeling is correct this person may prove to be an excellent reliable inexpensive source to have IPs repaired. He told me he had finished the pump repair & the total cost was $165 including shipping. 
I had a very interesting conversation with this person who told me he was retired from Chrysler Corp. & was involved in the engineering of the Cummings diesel for the Dodge pickup, & was involved with the VE pump used on the Dodge/Cummings. He said this was a Bosch designed pump very similar to the Bosch VE pump used on VWs except the Dodge has 6 cylinders. He said he was rather upset with some of these "Redneck Mechanics" who were messing up the Cummings VE pumps for more power which he said compromised engine longevity in order to "peal rubber" & dropped mileage on a 5 speed Dodge/Cummings from up to 27 MPG to 14 MPG. He also felt it was not right for some of these "Redneck Mechanics" to get $500 or more for an hours work rebuilding VW IP pumps, often improperly.
He also said you can't replace the big "O" ring at the rear of the IP while on the car. It has to be off the car & in a vertical position. So, I think I goofed in trying to replace the rear IP "O" ring while on the Quantum. I will also have a properly rebuilt & re sealed IP out of this. I will then have that one rebuilt & possibly use it on the '86 Jetta & go for the turbo kit for it.
Thanks to all who have provided tips so far & hope this long posting is of interest to others.
