I was an idiot and ran my backhoe/FEL out of fuel the other day. I believe I now have air in the line preventing the machine from starting.
I've come across a few videos online but I'm still not sure how to purge/bleed the line. Can someone explain how I should or can proceed to get the air out? From my limited understanding I believe I can use vacuum to pull fuel out through the return line. I have available a hand vacuum pump from a brake bleeder kit and also a 7 cfm A/C vacuum pump.
From my understanding I may have to purge or bleed the fuel line at a few different locations. I've also seen guys loosen injectors to bleed air out.
The machine is a 1986 New Holland LB-620. The engine is an Onan 4 cyl diesel.
The first pic is obviously not my engine but similar.
Second pic is Water Separator/filter?
Third Fuel Filter
Forth fuel injection pump?
Any help would be appreciated. Thanks
