Hi friends, I was working on my R4 and yesterday when I wanted to put it beck in garage the R4 suddenly died and it dident want to start again. I was looking around and I found that the fuel filter is empty. I tried to pour directly in carburetor and it starts immediately, runs for a moment and cuts off. So I now it's because there is no fuel. I was reading this forum and tried to start it with the gas tank cover of but no luck, tried to blow in to the fuel hose from the fuel pump and I just hearing whistling the air around the hose near the gas tank. What do you think, do I need to take the gas tank out?
Do you think there could be a problem with the fuel pump? If you disconnect the tank to pump hose and replace it with a length of fuel hose that goes to a jerrycan of petrol, does the engine run normally?
I tried today to start the R4 with hose from the fuel pump directly in a bottle of petrol and it started immediately and works with no problem. So I think the problem is at the conection with the gas tank.
