You can open up the head where it's filled in, install the eccentric and use the mechanical fuel pump. I've done this mod a few times in the past.

Look in section EF on page EF-16. There is a description of the Air Regulator. There is a electronic test for it on page EF-24 and a functional test for it on page EF-58.

Your link didn't work (for me) but your first scenario is correct. Closed when cold, open when above 134F.

That's pretty much what I said, isn't it?

That's Monroney.

Thank you for that unsolicited testimonial. (at least, unsolicited in the last 6+ months)

No offense I just like to keep it simple, that's all.

Generally, barring some type of mechanical problem, I think you'd agree that the pressure in the system would be higher than the atomspheric pressure. You're going to see the leak regardless of magnitude. No need to over think it.

It almost sounds like he's talking about a windshield wiper arm.....?

Thanks, Ronaldo but, you know, if I would have read your and Two6TZ's responses properly, I would have never made that post. Gary's talking about 'D' caps and you guys are talking about 'Z' caps.:embarrass::stupid:

For the last two posters: Pictures or it's

Where's the obligatory close up shot of the odometer? This car would need plenty of documentation to convince me that it hasn't been around at least once. Like esprist says, it look a little rough for it's description.

I've never seen it done and I've been around Datsuns for almost 40 years....there must be a reason. I've seen triple SUs but never triple downdrafts. Even with the twin 32/36s, (and 4bbls) I've only seen a small number of them run 'right'. I'm guessing it could be done; virtually anything can if you want. The only question would be why? There are enough available setups that are known to work. Why take on something that looks to be such a nightmare? As far as a 'conversion' goes, you'd need a manifold, linkage and, of course, another carb. I wouldn't really refer to that as a conversion. It would be more of a fabrication.

Atmospheric pressure? The fuel pressure regulators on there cars aren't that sophisticated. It sounds like you're describing a modern fuel pressure regulator. Let me take it directly from the FSM: When everthing is working properly, watching a fuel pressure guage shows a quick needle movemt at the hit of the throttle that instantly returs to 36.3 psi. so the fuel pressure is about as constant as it could be. If it fulctuates for any longer length of time, something isn't right. Weak spring, problem with the diapragm, fuel or vacuum leak, etc.

The pressure should remain constant regardless of what the engine is doing as long as there are no leaks, vacuum or fuel.

A 76 and newer has to be smogged in California. 75 and earlier are exempt.

Your first paragraph explains it the way I've always understood it. My experience is with a 78 however which basically uses the oil pressure switch signal instead of the AFM contacts.

According to the FSM that's normal for a 75:

Can he solicit off-eBay offers during an eBay listing?

I don't think a different shot or angle would help. It has a cover on it. Most extinguishers come with some type of mounting bracket and are fairly easy to install. Had one in all three Datsuns and plan to install one in the GTO.

That's normal operation as long as the AFM flap is open enough initially to close the fuel pump contacts. This is true for all 75-77. 78 and up don't have fuel pump contacts in the AFM.

I don't know, maybe it's just me, but I think car parts would be way down the list of things I'd be gathering up during an evacuation. I already have a photographic inventory of my garage and shed. Sure, I'd like to save everything I could but but there are many things in the house itself that would have a higher priority.

I realize you're speaking of you own observations but the 70 I mentioned that I owned 'back in the day' was HLS30-00488. It didn't hve a rear window defroster or tinted glass.EDIT: I just noticed how old this thread is......

This one? http://cgi.ebay.com/ebaymotors/Black-Pearl-Edition-Collector-owened-Very-nice_W0QQitemZ270460695463QQcmdZViewItemQQptZUS_Cars_Trucks?hash=item3ef8b6b3a7&_trksid=p4506.c0.m245

The first one shows no price and the last one which is somewhat modded and I really would question that someone paid $23K+ for that car though stranger things have happened. If you throw out the high and the low, you get an average of just under $13K. That seems to support rdefabri's conclusion: That would not make one want to look into these as investments at this point and time. And I don't think you can really put that on the present state of the economy. Muscle cars and non-Japanese exotics seem to still be selling at fairly obnoxiously high prices.
