B engine fuel pressure

[Catman76]

I was driving my 78 BJ40 today and noticed i couldn't take off in 2nd. When I got home I hooked up to some tires to drag snow. The engine lost power and sputtered out. It started and died. It's like it has no fuel. The tank is full. Any tips on how to trouble shoot the problem?

Has the fuel filter been changed recently?

It's quick, cheap and easy to eliminate that as an issue...

I wrote a small guide on this issue on a 2H.. almost identical engine to the B.. all relevant: 2H - Sucking Air/Fuel Restriction - https://docs.google.com/document/d/1qXKR1Vwj5sX6R6tVLRebIYl4J-5uoU4Xd6II2Rfu_9Y/pub

Thank you. The last injector has a plastic line that runs back to the pump. It looks damaged

Are they normally hard to get all the air out of? I replaced the line and got it running. I've bleed the air a dozen times

B and H series engines are usually very easy to bleed.. if you're still struggling you may still have a source of air ingress.
