I'm pretty sure there are no differences in the valves themselves. They fit together fine when I reassembled it the last time but I can easily pull it apart again to see. I don't have many of the original parts left. Most went into the trash long ago. I did find one of the valves as I was sweeping the garage floor a few days ago. The original springs disappeared when I dropped them the first time I took the pump apart.
I might just look for another pump in the wrecking yard if another 300D shows up. The spare IP I have doesn't have the lift pump. That lift pump is the one on my car now. I got rid of all old lift pumps when I sold off most of my spare engine parts a few years ago.
