3B hesitates aroudn 40 km/h

[Softride62]

Guys, wondering what could be causing this, in 2nd gear going up hill at about 40km/h it feels like I'm going to stall and then it keeps going. Also in 3rd and 4th around 60 km/h is has the same slight feeling of no power /hesitation like I'm going to stall. It starts up fine, and idles smoothly. It seems to do it more when going up an incline or hill ..any ideas? Fuel filter changed less than a year ago.

I had similar issue with my B and it ended up being the soft fuel line going into injection pump. It was sucking in air.

Thats your 1st job.

Its most likely either going to be something in the fuel delivery from the tank or an injection pump problem.
It sounds like it is RPM related.
You could set up a temporary fuel supply, bypassing the filter direct to the fuel pump (its only for a few minutes). If the starvation disappears, you know its in the fuel delivery.

update... it turned out to be gunk in the fuel tank from years of condensation, etc. Shaun from Land Cruiser Specialist in Austin drained the tank, cleaned it out, saw the the sock filter was completely clogged up and cleaned it up. He cleaned the tank with some E85, and done!! She runs better than ever now...thanks LCS!!
