1976 280z engine runs rough then dies, will not idle.

wow, that is bummer, poor QC and packaging. 

Yeah, right?

I did some calling around this morning and found that the OEM part no longer exists. Apparently it's been out of production / not available from Nissan for about 6+ years or so.

Called a few places looking for NOS or an unsold OEM part that had been sitting on a shelf, no such luck.

It seems that the only way to get one of these is the 3rd party Standard Intermotor part, which is what I ordered from RockAuto, but they sent me that used, janky looking part.

It's been ordered from another supplier and should be here in a day or so. (hopefully)

Will let you know when it arrives.

Great video above, I think I have a pretty good grasp of this part of the FI system after this crash course!

Was actually just watching your video on compression test.

Between your videos and Restoration For Beginners videos, there is just about everything you need to know about these cars online!

I'll see if I can add to the library as I do some work on my Z, but I'm terrible at producing videos so don't hold me to that.

yep too bad RFB dropped out of it, think he said he was starting a new job, have not seen anything from him in a long time. Never did see if he got the Datsun back together after the engine rebuild.

If there's a wrecking yard nearby you might check for a 1978 280Z or 280ZX fuel rail and regulator.  They will transplant over and it looks like you can get Bosch parts.

Edit - the picture they show on Rockauto is wrong but it shows right on Amazon.  Cheaper too.

I have a NOS 22670-F5101 sitting in front of me if you are interested. I believe it is what you are looking for but confirm that

I looked up that part number, and while it is for a Datsun Z car fuel pressure regulator, I cannot match the part number with any known part numbers for the FPR on a 1976 280z.

The corresponding part numbers I could find are: Alternate/OEM Part Number(s): 13531260789, 22670N09800, 22670N4200, 22670N9800, 22670N9801

Does it look like this...?

That's for the 78 280Z and 280ZX's.  One inlet.

 

[Patcon]

Zed is correct, only one inlet

[Patcon]

I might have a used one but would have to look

Thank you for the offer, but I would pass on the used one if only for the reason that it is more prone to a shorter life-span.

I have other issues with the car that need my attention, the FPR / running rich issue was an unexpected diversion from my original resto game plan.

OK so I have the replacement fuel pressure regulator in hand. It appears to be suitable upon visual inspection.

Regarding installation, I'm thinking I should probably take off the entire fuel rail rather than just trying to swap it out in place.

Thoughts on this....? (Pros - Cons)
