@Captain Obvious You have a GPS on your flip phone?!!

Do you have a pre-filter before the pump as well?

I agree with @Zed Head. You can count on those being destroyed. You may get lucky with the booster. Look at the bottom of the MC and see if it has been leaking and the paint on the booster in that area will be gone with rust residue. I wouldn’t put any fluid in either. Take them off first.

@cgsheen1 made a suggestion, Are you not willing to try it? Takes 2 minutes.

I believe he mentioned 10 plus years.

I’ve mentioned it some many times in the past about replacing each and every connector on the EFI harness and cleaning each connection in that arena. You will be amazed at the corrosion that you find on each connector and the wire itself. I had to shorten some wire by over an inch before I could find wiring that was suitable to crimp/solder.

I understand that, AI is a smorgasbord of articles massaged into one. He mentioned he was searching AI. The reason why I asked the question.

The most reliable source is the FSM that can be downloaded on this site

@Toiletduck34 Where did you find this reference material?

I do, I ordered another from Nissan to replace mine. When I get back in town from Boston, I’ll post the p/n. Can’t remember if it was superseded.

Nice work!

Grab another tach off eBay and go from there.

That front bumper is going to take 1st place hands down!!! Great job Bruce on making the trip!

Great Job Bruce!!!

Welcome to the forum!

Is this the same model you posted earlier?

Tachs are available on EBay the last time I looked. Easy to change out as well.

Could be the tach just said I’m done. These are 50 year old cars.

Much much better!! I know that’s Great English!!😂

While the Afm is out take a finger nail file and polish up the contacts on the wiring harness connection.

That’s good to know but there are quite a few different components compared to a S30.

Been There, Done That! Pouring rain. And Nothing like soaked pants on a bike!!

@mayolives Curious why you are calling your car a 79 280Z? Unless you went with the 79 ZX larger booster.

Myself and others here on the forum have had great success with Power Boosters Exchange. They are located in The North West. Rebuilt my original and they also can powder coat it for you.

The saving grace for my 78 model that was running extremely rich was changing every connector on the EFI harness. Cleaned all of the male connections. Finger nail file works great and reinstalled the harness. This was after months of trouble shooting. Doesn’t mean you don’t have other issues but you have a good base line to start from.
