Fuel flow DG1.9

[Darkhorse]

Gents, if the carb is removed from the van and the engine is turned over, operating the mechanical fuel pump, should i expect to see fuel being delivered from the hanging-loose fuel inlet pipe or is there some sort of syphonic action that requires the fuel flow 'circuit' to be complete?

Thanks

If the hose is hanging loose, you may have turn her over quite a few times to get any fuel through.
Alternatively, get someone to turn her over and look at the fuel filter under the drivers side next to the fuel tank! You should see movement there.
If you don't I would check the fuel pump and the fuel pump rod ( I had a fuel starvation problem recently and had it confirmed by someone on here who loaned me their known good fuel pump)

Top Tip- If it is the fuel pump, don't replace with anything less than a £50 pump

Thanks. While waiting on delivery of a carb part, I changed the fuel filter. I see there is an air pocket in the filter, perhaps 10% volume. I see if its moving when another pair of eyes show up.

It's quite common for there to be a bubble at the top of the filter.

The pump should deliver fuel if the pump is primed.
I removed the in line from the carb and turned over the engine, it delivered several healthy squirts

If your pump is not delivering fuel then the diaphragm is split or there is air getting in to the line.
If this is the case the fuel simply returns to the tank level
