I would put a threaded plug in that hole you see the block off plate through. Also the hole under the intake is the pcv valve. Does it have the valve? Those are 2 unmetered air openings you don't want.

When I bought my 77 it would hardly run, bucking spitting and sputtering. I tried everything and then ran a mirror under the intake. There was a golf ball size hole rotted out where the egr tube connected to the intake. Under where your block off plate is. I deleted the egr system. The one vacuum line that was left after the thermal vacuum switch, TVS, I hooked to a nipple below the TPS box I think. Somewhere down there around the bcdd. Just a little story of my 77's problems. I've got the pictures on my laptop I can post when I can. You might find a recall sticker under the hood on the passenger's side if your's was fixed. Mine was not and that egr tube got loose and exhaust gas ate up my damn intake.

I agree. Standing while working on mine sucked. It helped my back a little running the front up on ramps, I'm 6' according to the DMV.

Agree with you on this.

What! Can't hear you over these triples.

Yea Greg! You woke up my favorite thread. I've been listening to a lot of music lately. Coffee in the a.m, music in the p.m. Never heard this before and it's seven years old. I am not cool.

I'm getting ready to drive my 280 now that the heat has lowered in Alabama. Anyhow, plans so far are to remove tank plug to drain old fuel then run 2.5 gallon gas can straight to the pump, bypassing the tank. Hopefully the return will let new gas to flow back to the tank and into my catch basin never going through the injectors. I'm thinking Seafoam for those after replacing my 2 fuel filters. The OE can and the G3 out of the tank. Is it that simple? Thanks for any input. I've forgotten more than I remember...

So you have NASA level redundancy. Good thinking!!

The matte clear makes the look original to me. It smoothes out the metallic shadows and light spots you get from using rattle can grays. @CanTechZ hit the perfect look in my opinion.

The window sticker price breakdown from the dealership is my car's icing on the cake. When anyone understands the importance of that they are car people in my opinion. And it was $3,995 with the sports package, front and rear spoilers plus rocker stripes.

I bought my '72 and got all the paperwork then realized I was the 3rd owner. A doctor bought it new then sold to his younger partner. His wife wrecked her Ford and partial payed with the 240. The body shop guy never titled it, never got it running and 10 plus years I rescued it from Ford hell. Now my garage queen awaits me whenever I have time. I'll give it to my favorite nephew which will wizz off my sister for choosing only him but we're good buddies, just alike aka "a little goofy" but loved by all.

@moelk did this recently. he may have some advice?

That was my thought on clamping off the return line for a test. That's how I figured out my cts was off to the ecu and did the RadioShack volume knob tweak. Easy to do and cheap. I ran the tune knob in the cabin and had a lot of fun running different mixtures. There's tons of info on classiczcars.com but here's the basic straight to the point info... https://www.atlanticz.ca/zclub/techtips/tempsensorpot/index.html

They need to look like these. You say "comes up short", could you not stack enough washers under the valve to raise it?

A good Por-15 thread with one of the best videos I've seen from @240260280

Cheap and easy. Put rubber hose over the ends of needle nose vise grips and clamp the return line to "none shall pass". That will increase fuel psi to the rail/ injectors. If it runs better there's your sign.

I like the original. You have all the hose connections already there. They are a little tricky getting the cover and filter in place but once you get the carbs adjusted right you won't need to remove anything for a long time. The filters are still available from Nissan too. https://www.courtesyparts.com/oem-parts/nissan-air-filter-16546e3210

That thick gray teflon tape might hold it in place too? Good deal for $40 imho.

The only leather on my 1977 is the shift boot lace.

Might read something in here useful. Good luck.

I changed my LIKE to WOW. I've watched that 10 times that I know of and never noticed the Z. Great eye Zed Head.
