3406b fuel transfer pump install

Hello, I need some help cant seem to find any info, ive removed the fuel transfer pump on my 4mg 3406b and fitted the new one with the hose connections, i went to go install it and i cant seem to fit it back into the camshaft?, is there something that im missing? How does it fit back into place? I tried putting the old one back in place and it wont fully go in enough to be bolted back either.

 

What do you mean by trying to compress the plunger? When i put it back into the injection pump it wont go in all the way, not enough for me to be able to even thread the bolts.. what do i need to do?

 

Where does the plunger need to sit?

 

Ok, i got it now, im suppose to compress the plunger… kill me now haha

 

Thank you, just seems like it needed so much force i wasnt sure it needed to be compressed or not.

 

I still cant seem to get it, the position is very awkward but also the force required to push the plunger in while getting the bolt started is driving me crazy. Yes they protrude the same distance. What im wondering is do i need to center it then compress and then start the bolt?
