Yes, just remove the trunnion pin and let the rest hang there off the top trunnion.
Best to leave the arb link attached at the bottom and release it from the top, otherwise the arm might lose its alignment with the spring pan with the spring load on the latter.

I would have thought those porosity figures would have given a pressure at which the results were attained.

I would expect to see cracks etc in the filler tube if it’s leaking/ porous.
Also unless you fill to the neck or park on a very steep gradient fuel would not linger in the hose.

I haven’t noticed it on mine which is original 1972 rubber !

Leaking tank tops/ sender...

Cover it in PTFE tape Anam?
Correct me if I'm wrong, I'm sure you will, but isn't the ethanol in suspension with the petrol so with the ethanol escaping, won't it take petrol fumes with it? Or is that too simplistic?

Where's the surface plate and marking blue to check the flatness?

True Guy.

Thanks Dave.

Yep, I agree, I've got to sort out the flanges whatever gasket I use. Today I did a bit of welding and a bit of grinding. It's a whole lot flatter now, and now there's metal under all of the available gasket surface.

Flattened the flangrs on the inlet manifold too.

Tomorrow I'll bolt it up, again, and give it a try with yet another of the ...

<<Rover obviously thought they were OK for the job.>>

Except of course their job at the time wasn't to match up with a less than perfect version of a Maniflo !

"Dave have you tried those injection versions yourself? Are they good?

And, supplementarily,

1, how many have you got?
2. Are they for sale?
3. How much?

Lol

I see the top and bottom port widths are pretty 'thin' though; compared to Richard's old stock.

But perhaps those fire rings obviate the need for full width coverage."

I am pretty sure my smell, or rather, the smell of petrol in my car, came from the spare fuel van. When I inverted the can with the cap screwed hard down, I got a thin dribble of fuel coming out! Not exactly fuel or fuel vapour tight!

When assembling this car (Frogeye) I used R9 pipes throughout. But that still leaves suspect components in there. But I too use a Hardie unvented pump, as Ric...

Thanks for all the input. I tried winding the idle mixture screws out 3.5 turns and it started and idled better but spat a bit when opening the throttle then when it was warmed adjusted them equally till it stopped spitting back. That will do for now . Just got to take it all off again and swap engines. Wish me luck

And can you get R9 filler neck rubber Jeremy?

Richard, yep I checked both of those. Only my diaphragm vents to the boot. So I took it out to check and the smell remains.

It has to be the neck rubber, but nothing is visible.

And here's a thing.

If the rubber is permeable to the ethanol, I wouldn't be smelling petrol. Ethanol smells like wine or beer or hand sanit...
