I had my red top fuel pump mounted in the engine bay and did not have any problems fueling triple dellortos, but you are right they are supposed to be mounted near the tank to push the fuel.Interesting position of your pump. I thought the facet pumps were pusher pumps rather than puller pumps. I have the exact same pump but mines positioned up next to the tank pushing fuel down the fuel rail to a pressure regulator in the engine bay.
Yes, looks similar to what I was expecting but only top in and out connections and doesn't seem serviceable as cannot be opened. There is nothing in it except a few loose black bits which I got out with a few flushes and carb cleaner. It was pretty blocked with debris before I cleaned it. I would guess if the garage did put that pump in they didn't clean out the filter properly!When you say debris collector/swirl pot, do you mean the white/cream coloured object? because that looks like a OEM type fuel filter.
Update, my old tank had two fuel connectors of the same size low down in the tank. However it only had two other connections, the 19mm pipe to go and join the filler neck and a single 6mm pipe which appears to be a vent and seems to join straight to the hard-line which leads to front carbon canister. I don't see any evidence of a vapour tank anywhere. Certainly not like the diagrams I have seen on here or in the Haynes manual.
I think the vapour tank stuff is US market only...
Any thoughts on either the JDM Spec car or the 2+2 having a different tank dimension? It looks like it's the same capacity but slightly different lump to length ratio....Oh dear....... I just offered up the replacement tank and it won't fit.... It has a slightly larger bulge and is shorter overall.... Can this be right? The 2+2 (2/2) is known to be different in many areas, is this one of them?

Hi, thanks and this confirms my suspicions that it is different. In fact the tank fits so well in the car, it appears original. The larger bulge on the replacement tank physically won't fit. It was from a 1971 240z but don't know which market.Again, as I think I tried to point out on your other thread, your particular car's production period is right on the cusp of a number of rapid changes and parts supercessions linked to prep for much more stringent anti-pollution regulations in Japan. Pinning down the exact spec of your car's OEM fuel tank and related components is very difficult and the factory parts lists for the Japanese market models around this time period are a real minefield.
Added to that, there's no guarantee that the tank in the car is the original in any case. Anything could have happened since it was made. We came across a big question mark in your other thread when you pointed out that both feed and return pipes on your tank were the same size. I was expecting - for a 1975 or earlier non-injection car - for the return to be smaller than the feed, and for there *possibly* to be a vent line linked up to the engine bay, but apparently not the case.
There are any number of possibilities for size/fit/connections, and most of the English-language data and anecdotes you will find on the 'net apply to Export market cars, and predominantly USA market cars at that. This may lead you astray. The fact is that - as the owner of a fairly rare Japanese market variant - you are going to need to be self-sufficient in parts and information up to a certain point.
If I were you, I'd try to refurbish the tank that you removed from the car. At least you know it fits...
