How long has it been sitting since it ran out? If you do it like SJ says, and it still won't push fuel out the injector lines, then the rack might be stuck. You should be able to bleed the filter tower though.
Another trick is to clamp a piece of an innertube with the valve stem in the center of it over the fuel tank opening with a large hose clamp. Put in air until it bulges out tight and then open all your bleeds to let the air out of the fuel system. A lot easier on the cheeks and ear passages than the "old fashioned way"!
If you fill your tank plumb full it will bleed by gravity.
sounds like you may not be getting enough pressure through the filters. Have you replaced them? The gauge reads the pressure AFTER the filters, so it's showing the net pressure that forces the fuel into the pumps. Clogged filters or bad relief valve will cause low pressure on the gauge. Both are a pretty easy (cheap!) fix compared to the transfer pump.
When you have the relief valve block down, check the fuel flow from the tank to ensure that's adequate.
If your line is cracked somewhere in the middle, you can braze it up. Should be plenty of used ones around if you post your serial number. Easy to mail one too!
I checked the filter and it looked clean as did the chamber. So I suspect the regulating valve is gunked up. It did inject on one or two cylinders though because it popped a few times. I had to leave though. She's about 1000 miles away so I can't see'r too often.
I think the collar was split on the fuel line. I could probably get one off another line and reflare it. I can't remember now what it looks like- worked on it last summer.
Thanks,
Rob
