Also called Hoopers Rear Ends and were still at a standstill with the rear end. I bought a 4.38 truck pumpkin/ 3rd member and my LSD unit wouldnt fit inside of it, so I suggested using my Roadster pumpkin/ 3rd member that has a bad 3.9 and swapping in the 4.38 gear along with the LSD unit, but he still doesnt feel like it will work... why is this so difficult for me... im a bit furstrated as I was hoping to have the rear end wrapped up so I could focus on the motor once I have my head back.
so as this continues to be a headache, its time to ask again for help. I was going to rant, but nobody cares to hear about it, myself included...
Hoopers tried to take the 4.38 ring and pinion and install it into the Roadster sourced 3.9 pumpkin/ 3rd member and said that the bearing sizes are different. In other words, the 4.38 and my LSD unit wont fit together in the aluminum pumpkin/ 3rd member from the truck, and they wont fit into the Roadster pumpkin/ 3rd member.
If ANYONE can help shed some light on this I would be very grateful because Im now on month 7 of the Roadster on jackstands and this was supposed to be a ~3 month deal... I miss driving my car
First I'll say I have researched for a while before asking this question. I also fully understand the mechanics to each piece in pump and how they function.
That being said - Can someone here show how to install a new diaphragm in the fuel pump? A video of this would be great. I can remove the old diaphragm but I am having difficulties re-installing it to the lever. Oh and last thing I tried was to remove the pin to remove the lever... does not work. There is a metal ball on each end locking in the pin (even though some instructions say you can remove the pin with a punch - and I have even seen this done on a different style mechanical fuel pump on youtube)
Here are pics for reference on the type of pump and style diaphragm.

Mackn367, if you can get the old diaphragm out, compare the old and the new. Careful inspection should let you see what the problem is.
So the old diaphragm is identical to the new diaphragm both having the â€œTâ€ at the end. Iâ€™m basically having trouble pushing the new one in place where the lever gets locked in with the diaphragm.

This was a good idea when we started it but we are already at 99 pages again. Plus the fact it is hard to follow. So, with that in mind I am locking this thread down as I have created a new forum where you can post your quick/small/stupid questions there. Just submit your own thread and we will easily be able to see if your issue/issues have been resolved or not. The new forum is at the very bottom of Datsun Sports Roadster Discussion Topics. Thanks.
