Is it the fuel gauge sender? Once upon a time I had my tank out to clean, paint and seal. When I put the tank back in I buried the sender unit wires between the tank and the car. Had to lower the tank to pull the wires for the sender out.

Yes, the round tops have a heat shield between the exhaust manifold and the carbs. You can see the heat shield in this shot

I'm guessing that with too much advance on the spark you get the firing happen during the compression stroke which pushes the piston in the opposite direction of travel which may damage pistons, rings or other bottom end components

I'm thinking of all new suspension rubber, strut bearings and the Koni's with stock springs. Found the OEM insulators for the $64.21 on Amazon with free shipping which makes the price difference from after market only about $40! https://www.amazon.com/1970-1978-Nissan-Front-Insulator-54320-E4100/dp/B00TNL7LTK

This part # does not show up on https://parts.nissanusa.com/ Where were you looking?

So nobody has an opinion or knows anything about the $48.00 strut mount insulators?

I thought the taller ones were a 280Z thing. https://zcardepot.com/products/upper-strut-mount-spacer-240z-260z-280z?variant=19280977494129 The rear spacers for a 240Z are only $11.00 for the pair https://www.thezstore.com/page/TZS/PROD/classic20h06/23-4166 so they will match the the size of the upper front bearings https://www.thezstore.com/page/TZS/PROD/classic20h06/23-4376

I'm getting ready to go through the suspension on my 71 240Z. I find that OEM strut mount insulators are ~$80.00 https://zcardepot.com/products/strut-mount-upper-insulator-front-rear-oem-240z-260z-280z and after market @ ZCarDepot are $48.00. https://zcardepot.com/products/strut-mount-upper-insulator-front-rear-oem-240z-260z-280z-1 Anybody have experience with the after market ones. The saving on all 4 is like $120.00 for the aftermarket.

Glad the kids are okay! The car doesn't look beyond repair.

Why not just use an inertia switch to cut power to the pump in a crash. https://www.amazon.com/Ford-5L2Z-9341-Genuine-5L2z9341a-Inertia/dp/B000NTI03C/ref=sr_1_2?keywords=ford+inertia+switch&qid=1558051529&s=automotive&sr=1-2

Thanks to both for the replies re: high altitude!

I wonder how much effect altitude has on all this? Those of us in the Rocky Mountain region of the USA are typically at 4,400 elevation or higher.

On my 240Z I had interference with the thermostat housing too. I ground a little off the thermostat housing flange.

I had only heard of torque steer on front wheel drive cars. Did they do a full alignment after all the suspension work?

Thanks, if you remember or find your receipt, please let me know! Thanks.

@jalexquijano Is the air filter box shown in the 1st post in this thread on your 240z? If so, where did you find it? Thanks, Wilkes

Finally found the thread! The picture is in a post by @siteunseen found here Hopefully he knows where that air filter box came from. I like it. Wilkes

Is it metal or plastic? If plastic it looks like the push out center of the plastic interior panel rivets. https://www.dkhardware.com/datsun-trim-panel-plastic-rivet-cp764361-product-14721.html

Yep, see it now that you point it out, thanks.

Looks like one of those old 2 part forms where the bottom is snapped off and kept by the dealer. Looks like your customer portion is complete, the total for the car and upgrades looks like it was $8155.07. Looks like he might have paid cash.

Can't remember which thread I hoovered this from. Is this a custom made air filter housing or does someplace sell these? Looks like it takes the stock air filter.

You should read through tis thread, it talks about doing exactly what you're talking about. It does sound different than doing the electric pump in the early 240z's though.

I would bet the cracks in the dash were filled with this stuff https://www.dkhardware.com/black-777-butyl-rubber-sealant-777BL-product-2447.html?gclid=CjwKCAjw-4_mBRBuEiwA5xnFIBQfHTBg2iE-JxhkcjWrR0vuu_tw70dhEOyRHfFU_6Hs4p19EiTBdhoCuNQQAvD_BwE#description

My early 71 also had those almost useless knobs. I swapped in some seats from a 77 280Z, new foam and leather from Interior Innovations, and now have the flip forward option which is really nice for access to the jack and tools under the plastic hinged covers.

If this means do the Headlight relay kit too, I completely agree. I've also done all external bulbs to LED to lower the power draw throughout the wiring harness.
