Scro,
That is just under 1,000 miles. Staying together and not catching fire is a "calculated" risk.
What is your timeline - that will determine your options.
1. Have your new pump shipped to you and install it before leaving - NOT realistic in a motel parking lot...
2. Both scout4bta and I had good luck whit VE pump rebuilds from Perkins Diesel in Mesa, AZ. Had mine rebuilt last month - extremely happy with the work) Again, assumes you have a place to do the work.
NOTE: My 76 year old body did NOT appreciate the contortions required to remove and replace the VE pump (had to move the AC compressor and the vacuum/power steering pump for access to the VE pump - poor design on my part...).
3. Stick it on a UHaul auto transport trailer and tow it back behind a UHaul 15 foot truck. I failed a U-joint in Flagstaff (F150 below) on a late Friday afternoon. Did not want to search for reliable shop that was open on Saturday, and rented a UHaul truck and trailer.
NOTE: Not all vehicles are "legal" on a UHaul trailer, my 1975 IH Scout II was not, one of the reasons I switched to the F150.
