Interesting, I don't know where else to look for vacuum leaks. Unless one of my lines has a crack in it.

You'll be amazed at how simply we can accidentally knock one off, or have a back fire blow one off. Your on course for learning to love your bus

You'll be amazed at how simply we can accidentally knock one off That's for sure! BTDT!

Yup, I agree, something "sucks" big time. Stan

Reviving an old dead thread here......but I've finally got this bus on the road thanks to Russ. She runs and now I'm hopefully just going to be cleaning it up and fixing small things along the way.
First up...the fuel sender. I'll post pics later. I've tested the gauge, now just trying to get a reading from the sender. It was pretty dirty and covered in rust, but any tips on cleaning this up and where to look for damage etc?

I was puffing smoke pretty good and found that I was dripping oil on the exhaust pipe, so I fixed the seal on the valve cover.

I hate it when those valve cover gaskets do that! For the benefit of others that have read this thread, here is a list of what was wrong with this bus: No spark at first due to the way the condenser connector had been installed. The plastic block that contains the condenser end terminal attaches to the outside of the distributor body (the metal terminal itself pokes into the side of the distributor. The ignition points wire attaches to this terminal. The metal terminal tab points upwards when installed correctly. This one was installed sideways, so when the points wire was attached, it touched the baseplate and and was shorting out. Installing this correctly allowed spark to occur.
The fuel pump did not run either. The wiring to the pump was repaired first, but the pump still would not run. Stale fuel was the culprit here, which damaged multiple pumps. It gums up the insides of the pump including the electrical parts. The pump was replaced, and the fuel was drained and replaced. The above picture of the fuel sender, shows that the inside of the tank is probably not very pretty...
Now spark and fuel were present, and it started and ran very poorly. Compression was checked, and was basically zero on the right bank (#1, and #2 cylinder). Checking the valve adjustment revealed that the push-rods had fallen out of position and were holding the valves open all the time. Two potential causes for this: Someone was in there and did not install things right, or the valves stuck in the guides at some time which could cause the pushrods to fall down. Either way, installing the rods correctly, and adjusting the valves gained the lost compression back.
Then it ran fine at first, but out on the initial test drive, it lost power again. This was traced to two injectors that had plugged up, and were replaced with some used ones. Again, that bad fuel was the likely culprit. After this it ran fine for the next test drive. Unfortunately when Joe picked it up, it intermittently conked out on the way home. He cleaned and tightened the battery terminals, and hopefully that has cured the stall outs. Anyway hope this gives others and idea of what it can take to get that old bus up and running again after a period of sitting around. Sometimes it is easier then this however...
We once had a Champagne Edition bus donated to the shop years ago as a parts vehicle. This bus was rotting next to one of the marinas for years and was jammed full of old wood and parts from boats. (Don would like that). Anyway we needed a transmission for a customer bus one day, and decided to see if we could get the old wreck running to see if the transmission was any good. So we cleaned the fuzzy points, smelled the fuel which reeked like turpentine it was so old, and cleared enough junk out of the way to barely squeeze into the driver's seat. Adding a battery and turning the key to see what would happen. It cranked briefly, and started up like it was a daily driver! The exhaust smell from that nasty old gas was something else however...
