Priming Fuel Lines for a Dummy - Land Rovers Only

brandoninaz · 06-04-2008, 03:43 PM

Hey guys,

I'm working on my 71 Series IIA right now. I just removed my fuel sediment bowl, cleaned it, as well as resealing my tank and painting it. Now everything is back and place and I'm trying to prime my fuel lines.

I assumed to do this just by pumping the little lever on the fuel pump, but a couple hundred pumps in without results, and I'm having some doubts.

Is this the way to do it, or am I going in the wrong direction?

Thanks

That's the way to do it, but maybe the bowl isn't sealing. You can also help it out by sucking on the fuel line while pumping it, keeping an eye on the bowl so as not to suck gas. Or the lazy man's way of buying a low pressure electric pump and putting it inline with or bypassing the stock pump. But if you have a Weber, then a fuel pressure regulator is needed.

I'll probably try sucking on the line tomorrow. There did seem to be a seal on the bowl though, as there was definitely an increased resistance on the lever compared to when I broke the seal.

I'll report back tomorrow and let ya know what happens.

BTW it's a Zenith

There is either a rubber or paper gasket that goes between the bowl and the pump. Make sure that you did not lose or tear it. If there is a tear or it is missing, then you get an air leak and no pressure. I also find sometimes it helps to fill the bowl with gas (seems to help for me, not sure why...)
The easiest way is to dump a small amount of fuel down the carb and start the engine, adding the fuel again before it dies. Let the engine do the pumping and save your hands for something more useful...

Well, I finally got it by sucking on the line.
Thanks for the help.

You can test it by removing the inlet line and holding your finger over the port while working the lever. You should feel suction on your finger.
You can do the outlet port the same way and see if you feel pressure.
If you ever have the problem again. You pump may be weak, I've never had to suck on the line unless the pump was faulty.

I hope the pump isn't faulty, it has only been on the truck for about 150 miles.

BTW, I could feel pressure.
