Did you remove the check valve on the booster vacuum line at any time? If you installed it backwards that will cause the problem you are describing.

It’s truly a journey. Been there and it takes awhile

You are correct… That pan is thick aluminum and the baffles inside are just amazing. Not sure I will make it to the track. It’s a stage 4 build from Datsun Spirit. Eiji did an amazing job.

@Mike I guess it’s going to be just like the ocean, It’s not going to stop.

What threw me off is when he reffered it to a belt.

My aftermarket did not include one or referenced it. That might be a Wilwood exclusive. Personally you wouldn’t know when the rear seal is going bad. Probably would drain inside the booster IMO

Try the Wix filter. I had no issues on my 78Z. I did install a S30.world tank as well.

@mike can’t you bring an end to this. It keeps changing usernames. No trace of a MAC address to block?

Are you running the Bosch factory pump? It worked perfectly on my 78 280. You could have a tank problem with the strainer. There was a good reason why they went with the 3/8 input to the pump and 5/16 output.

You will probably bee surprised how it pops out. I’ve removed quite a few. There’s also a seal inside the cog shaft that prevents oil going into the cable. The ring and seal are still available.

Your prying on the captive nut not the cable.

I assume you are not using a factory pump.

As @Zed Head said, pull the spayed ign. Off the terminal and measure the voltage. Black to Gand and red on the spade turn the key to start.

I think you are perfectly fine
