Bogs down and wants to die on heavy acceleration.
Any ideas?

Though I'm fairly confident fuel pressure is high and consistent up to carb.

I have seen that before, open enough to run and accelerate lightly but not enough flow for hard throttle. | | | Re: 1985 dodge b150 starving for fuel | Joined: Mar 2007 Posts: 4,463 Likes: 12 pooh-bah | pooh-bah Joined: Mar 2007 Posts: 4,463 Likes: 12 | Since you're seeing this during heavy acceleration, have you checked the throttle kick down adjustment? It's the sliding rod which couples the throttle mechanism to the transmission. It's notorious for causing such issues. It adjusts fluid pressure in the transmission, so it's a big deal.
Do you have a service manual? The adjustment is described in the section on transmissions. I could dig up the adjustment procedure if you don't have it.
Also, the kick down rod should be spring loaded at both ends; be sure the springs aren't missing.
While you're in that area, before making the kick down adjustment, make sure that when you push the accelerator pedal to the flood that the butterflies are actually opening fully. If not, you can adjust the opening via the threaded rod which couples the accelerator pedal to the throttle mechanism on the carb.

I’d install a gauge before the carb. I think 3 to 4 psi should be good. | | |
