Red7. If they say its good in that location, then go with it. I assume they would know more than me. Here is an updated photo of where I installed mine in the factory location. The pump bracket shown came on my 72 from the factory.

I really like that set up much better than mine. My Mikuni manifold made in the 70's does not have the adjustable arms like yours. I just may have save and upgrade after seeing yours.

Pop's, funny you should mention that. I have been thinking the exact same thing. Its getting time for the 4:11 lsd diff. to go. Been 20 years since I ran my last autocross. Just cruise the roads now. I got old. I see you are in Fort Collins. I remember a trip to Fort Collins back when I was stationed at Lowry AFB in Denver. Four of us drove up to see check out the pubs. It was a hell of a drive back. In fact we had to pull off and sleep in the car. What happened when we woke up is another story. Ha.

That is the pump I use in the rear. I am not too sure that location is going to work. I have never seen one located there. I think that is a pusher pump. Not made to pull fuel. Maybe someone that has done this can tell us.

Is your email system down? Very hard to get a response from your site.

The idea of a badly worn crank drive gear and or distributor spindle gear sounds like a possible culprit. I would like to see you drop the oil pump and spindle to inspect both the gears.

Put the shocks up for sale here if you are not going to use them. Somebody could use them and you could recoup your money spent.

Montana Tools are made in USA. Very nice. http://www.montanabrandtools.com/collections/all

I have a free differential mustache bar if that broke. However, its for a R180. Jai's could be a R200 though.

Another thing you guys will want to do is check Jai's distributor vac advance unit with a hand pump vac. Very important that it works for both good running and good gas mileage.

It actually sounds to me just like the factory one. I run a stainless Magnaflow muffler and really do not even notice the pump running while driving.

Those are good numbers. Especially if a cold test.

I am using the Facet 1105 pump. It is a dead on match replacement for the factory pump. Using no regulator and its working perfect. https://www.pegasusautoracing.com/productdetails.asp?RecID=85

What is under that distributor rotor? Points? Electronic pick up?

Yes, you can see the head has been off as with the valve cover off, is real clean. I also see its a E88 head with no spray bar. Internal oiled cam?

I like the two tone paint job with the white engine bay.

I am useing the BP6ES-11 with my Pertronix ignition kit with Pertronix coil. Works well.

You can buy those right from MSD too.

Download the Factory 280Z FI Manual. Its excellent. Will give you the full understanding of how your system works. We found 280's are even running around with plugged up exhausts. A definite mileage problem. Honda's and Toyota's are famous for the same thing.

Pull all 6 plugs, not just one. Also run a compression test. Report PSI of each cylinder.

I ran a fuel pressure test right at each carb with no return line and got 3.5 psi. I then did the same test with the return line hooked up and got 3.25 psi. I decided then to leave my return line hooked up. Continuous cool fuel supply that way. This is without a fuel pressure regulator of course.

My issue turned out to be that holley regulator. It was restricting my fuel flow or pressure or both, I don't know. But when I removed it, It solved my Mikuni problems. The car would loose power like it was running out of fuel. A sledge hammer took care of that regulator. I made sure that was never going on another car. I was a little pissed.

Is this the single seam? Shown at the bottom of the wheel. Are you referring to the dual colored ones as the 3 seam?

I have put those on 3 different cars. I was not aware there were different ones. All 3 I installed were exactly the same. Never heard of single and three seam.

This just happened to my 72 two weeks ago. It was just a blown fuse on mine. So far so good. If it blows again then I have an issue.
