84 Fuel delivery problems solved
I replaced the filter.....no change still almost ran. Removed the Fuel pump and found the hose connected to the fuel pump with a 1/4 " split in it, so it was pumping fuel back into the tank. Replacing the fuel pump anyway since I'm this far (with an 85 pump) no sense in being cheap and stupid.

Looked at three pumps, all had a slightly smaller dia than the original pump (fuel exit). Took a 5/16 dia hose softened by heat in water, slipped it over the exiting steel fuel line (3/8 Dia) and slipped the other end on the fuel pump (5/16 dia).

And yes, the pulsator hose eventually turns to mush. You can just replace it with a section of fuel injection hose.

Write down somewhere that you've used a different fuel pump, because if the regulator fails or you have injector problems, you'll go crazy troubleshooting.

I had the same thing happen, I was getting fuel to the filter, so I thought the pump was good. I went to alot of trouble to find out that little hose was deteriorated.

Common mod for the L83 (82 & 84) is to use an 85 pump.. You get a better fuel supply (Volume) to the regulator & injectors and better throttle response.
