One final silly question before the fire-up...

Hey folks, I'm all ready to fire the engine up, start is working and all systems are go, I just have one final question regarding fuel supply. Does the tank -> pump line syphon fuel to the pump, or does it rely on the pump to bring the fuel through? I know this sounds like a weird question, but I was just thinking how the hell will the pump drag fuel through the line if the fuel line is empty. Won't it just pump air through? I've filled up the carb and fuel line between the carb and the pump, but I really don't want the thing to run for a minute or two until that fuel runs out and then just shut down. Thanks.

Unfortunately it's pissing down with rain here (as per usual these days) and day light has all but run out, so I'll do the fire up tomorrow.

The pump will suck the fuel through. The tank is sort of gravity fed although it's not a properly setup gravity fed system.

Does this mean that the fuel line will be dry and therefore no pumping will occur? Or will gravity have forced fuel into the lines?

Lines will be dry will the pump tries to draw fuel though it.

Re: One final silly question before the fire-up...

So how can I fill the fuel lines up before starting the engine? Or will the pump successfully pump all of the air out of the lines? Sorry if this seems like a dumb question but I really want everything to go right the first time for once.

If oils primed? Just fill the bowls by hand. Another way it do undo the carb end off the fuel line and compress the tank with air. You seal the tank with a thick rag.

It should suck fuel from the tank despite the lines being dry - it will create a vacuum. May just take a little while.

Cool thanks for the advice guys. Will let you know how the fire up goes tomorrow (if I'm not too busy driving the thing - fingers crossed!!).

Do you know how dangerous it is to run one in the engine bay. I would hate to be you if the line popes of.
