Fixing a holy fuel tank

[AliK]

Someone once told me they didn’t fit them to the later ones which seems odd to me. [emoji848]

Very possibly rusted off or ditched by a PO at some point. Inspecting it today, I noticed a broken off screw / bolt in a hole where it goes. Regardless, looking at the damage caused without it and given that the road dirt aims directly at the filler neck area, it’s an absolute must have!!!

The 240 had a complete rubber filler for the fuel tank which I think is the reason why it was fitted, but I’m not sure that was for all markets. Where as the 260 had a mainly metal filler with a rubber connector negating the need to for a shield. That’s my theory and I’m sticking to it, until Alan says otherwise.

Different part numbers for 240z and 260z. The image of an early 240z one in the parts manual is different to all the others I’ve seen.

Interesting! Thank you!

That diagram also has a breather pipe pointing the right way around (which of course to purists is the wrong way around)! Or did Nissan ever flip this annoying thing!?

Has anyone used a place that uses the american "Renu" fuel tank process? My 280's tank is full of rust, but the only place I've found in Manchester is https://www.tamesideradiators.co.uk/ . Spoke to them on the phone and they said they fully chemically and mechanically strip the inside and re-line it, and also do the outside - for between £350 and £400 +VAT depending on how bad it is.

Only thing is, they will cut it open in several places to give better access. Does that sound ok?!

S30 World replacements are now around £670 delivered, in comparison.

Sure, as long as they're the ones sealing it all up again ;-)

I took three days over the whole process of doing our 280Z tank. The inside was like treacle and was rancid. The outside was excellent but the paint was thin and worn. I think I documented the process in the thread that we started for the car if you want to dig into it yourself. That time covered steam cleaning it out, unblocking a blocked fuel return (which was totally random and looked like a lump of dislodged limescale), acid cleaning and treating it with POR-15 and finally cosmetically prepping it back and giving it three coats of black paint outside. It was a nasty and time consuming job.

I can’t pretend to know about other models, but our 1978 280Z had a fixture inside which resembled a coffee can, which I can only imagine is a surge protector. Inside that there is a strainer. My concern with lining mine was whether the lining would occlude the strainer or block one of the smaller vent passages as it cured. I set up an airline to purge these for an hour after tumbling the POR-15 around inside.

On the upside I found an american dime in the tank. I may never have got that back if I’d have taken it somewhere else to be done. Silver linings

Thank you - that could be invaluable info! I'll have a look in mine for the same thing. Mine's a 76 so it has the same tank as some 240s and 260s I think.

Silver linings indeed!
