Looking for any other tips on why I canít get gas to the carb. This one is weird. Canít seem to figure this one out.
The bus had been sitting for only a few months. The PO drove to my house when I bought it. (Itís a 1966 deluxe with a 1600 dp).

When I went to start it a week ago, nothing. Tried a few times and I could not see gas in the fuel filter. I should have primed the carb but I didnít.
I took off the fuel pump and thought I would rebuild it thinking that was the issue (which I have not done yet); and I put on a new pump and rod, stand, gaskets, etc.

This engine has a 12V generator so I bought the pump and rod meant for that. The rod measures 4.25 inches. Watching the old Bug Me Video and others, I made sure that the stand fits in smooth/slight loose to prevent a vapor lock.

Gas IS getting from the tank to the pump but not to the carb. I have primed the carb and it does turn over and runs for the few seconds it has gas in the carb.
When I take off the line that feeds the carb, there is residual fuel inside the hose where it seals on the long nipple on the pump. I verified I have the lines leading on the correct input/output from pump.

Last night trying to watch videos, read online, and just donít know what is up. Any suggestions before I call someone smart to help?

Thank you
-Mark

try swapping the fuel lines on the pump. sometimes these after market fuel pumps are backwards and the in/out lines are opposite from the older ones

I ordered https://www.wolfsburgwest.com/cart/DetailsList.cfm?ID=113127025B and https://www.wolfsburgwest.com/cart/DetailsList.cfm?ID=113127307

I assume they work in concert together. AND the rod that was in there, is same size, so not sure the rod is the issue... I think

That looks right, so yeah, check your connections, flip the hoses.

Thanks...

My fear is if that isn't the issue, I have no idea what is next... apart from calling that "smarter" person Smile

might be your accelerator pump.. Only sat for a couple of months but bad gas can be a factor.

Make a fuel proof funnel out of a plastic fuel filter, and use that to fill the carb float bowl via the hose from pump to carb.

Then with fuel hose reconnected to the pump, try starting it.
