Are all Belt driven pumps right spin and all gear driven pumps left spin?. Looking at the Belt and the Gear driven 4j engines with the timing covers removed it would seem that way.<br/>i have eyes on a gear driven 4jg2 pump but i can't see the VE4 part number so i don't know if it is left or right ...

OK then that sounds good, because for the life of me I can't get my hands on a working jb1 injection pump

Planning to use a G2 pump with the B1 cam plate. But will the injection pressure get up to B1 level?

But the answer is yes anything is possible hehe

no computer all mechanical

Good day Gents,
is it possible to convert a 4jg2t idi pump to work on a 4jb1t?.
if possible what mods are needed?

MISTIRIODES, in the last sentence where you state "next step is 4jb2 pump with mods...did you mean 4jg2 pump with mods?
