    Posted: 27 May 2010 at 6:45pm
Anybody ever experienced air getting into 7000 series Allis fuel system.? A friend borrowed my 7030 to run his round baler when his JD 2955 broke down.  He ran it really low on fuel he stated.  Anyway, it did not want to start.  Finally got it going and noticed bubbles in the water separator. 
 Is the pump looking device to the right of the water separator the manual pump.  I do not have a manual on this...bought it last fall at an auction.  Ran great until I got it back...I poured 5 gallons in it started it to pull up to the fuel tanks and it ran for about 10 seconds.  Wouldn't start after that.  Used ether to get it going after looking things over.  It runs now but acts like it still has air...not burping it all out.  Unless any other thoughts...I am open to them.  Like to get it running well again...still have have 12 acres of my own hay to finish.  Thanks.

I,d loosen 3 of the main  lines to the injectors to bleed them and keep it running ; it,ll run on 3 and the rest should clean themselves out ; hopefully

My 7040 did that too. It was main fuel line from tank to primer. Had small crack in it and would suck air when running. I replaced plunger on primer pump twice and messed with it for 2 years. I was about to take injection pump off when I found a soft spot in main line, after I topped it off of coarse! Drained all the fuel out and replaced line and runs fine now. Hopefully that helps someone out.

It may just not have all the air out of the system yet, but it should clear up. But if not, one way to tell where leak is, is to take supply line lose from tank and with fuel in line put a little air pressure on line and it should drip fuel where the leak is.

When your run it out of fuel you need to bleed the system. Meaning that pump under the filter.

A good auto parts store should have bulk 5/8 fuel hose.

If your 7040 is early enough and hasnt been updated, it will have the draw straw in the tank and the small plastic tubing. Not a great setup, best to convert to bottom draw with the 5/8 hose. If you dont have the fittings, most salvage machines still have theirs, takes a goofy fitting on the square filter housing, best to get the tank fittings as well.

Great time to add the optional auxillary tank if yours is not equipped.

If you need parts for your Gleaner, we are parting out A's through L2's, so we may be able to help.
