Sounds like the max fuel is ok if you could make it smoke by adjusting the compensator base point
carefully remove the boost enrichment top and turn the diaphram about 100deg clockwise and then try
that added 40bhp to my 2.8 on the rollers |
found this very interesting. http://www.dieselbombers.com/5-9l-rotary-bombs-aftermarket/9442-1989-dodge-ram-ve-pump-tweaks-cheap.html
i have a much better understanding now how the pump works and why the tweaks work..
i love when a plan comes together, when i get the time the intercooler is coming off so i can start to play with the pump.
will post here to keep you all informed of the mods and out comes,...... |

Ok , turning the diaphragm gives more fuel flow as it turns the long stroke pin
turning the star wheel alters the pre load on the diaphragm , I e you decrease the preload and the extra fuel comes in with less boost, caution with the star wheel as too little pre load will make smoke, heat and bad mpg
start by turning the diaphragm 100 deg clockwise and see how it goes |
