I have a large collection of documents that I'd like to add. 

I can easily add to my (public) library on caterham.dk if there's something you feel like sharing

Effectively it's not taken from the top off the tank.  The feed pipe goes to the bottom of the tank.  So in fact there is a very small net column of fuel to provide pressure in the feed pipe.

Exactly

No it's not a gravity feed pump as such.  The facet can and does "suck".  If you look at the pump spec it says how much.  Something like 12" iirc.

True. I've just realised that the feed is taken from the top of the tank 😮

I wish I undertood that. I iove the confirmation my hose is safe. I had thought the pump was sucking (ok, atmospheric pressure pushing) the fuel from the tank buit it seems not. Gravity is pushing the fuel downwards, so what's this about it pushing the fuel up and out of the tank? 

edit: I was readingt this too https://physics.stackexchange.com/questions/599287/what-is-gravitys-relationship-with-atmospheric-pressure

but not really much the wiser

I guess it will be a combination. But when the engine is not running it will be the static pressure - which may increase on braking, but it won't form an issue at all

Thanks for the explanation.  You are thinking of the feed hose from the tank to the pump?  Makes sense.  I thought your comment was referring to the pressure side.

Yes, exactly. Or you could say the pressure in that specific hose.

I don't really understand this comment.  What is gravity pressure please?

https://www.sensorsone.com/mh2o-metres-water-column-4-deg-c-pressure-unit/

There is no pump in the tank so the pressure will be max what the gravity produces (I think you also use the term "water column" for the pressure the fluid has when lifted above level and 1bar equals to 9.81 meter water column) so even if we count both the tank's level above ground and the height of the tank the top level will be less than 50 cm above ground the pressure will be less than 0.05 bar. No way it can push off the hose.

That should not form probems. Mind you the fuel pressure is limited to the gravity pressure

This might be useful (with an assembly guide for your car), which you might be able to download from http://www.caterham.dk/Assembly_Guides/index.htm

I've got one in Denmark you can have free of charge except from postage, but to be honest I don't know about customs.
It's off a 1995 live axle car

Gauges playing up could be as simple as the earth wire failing

I've had one of these too.

And if the titanium nuts were available for MB wheels ... MMmmmm

Hi Richard,
Just to register:
I might be interested in the engine.

Brilliant job Andrew. Very impressed!

Just polish the one you have and pull a glass mould ;-)

YHM back - and payment has been sent, Thank you Mark

Mark,

Can I have them? I hear you'll meet up with AB at Goodwood anyway, and then he'll sit on them for me.

I would need your bank details or an email for PayScam

Swop the camera plugs and see what happens

If the main image is still OK, then it's the VBOX, if it moved the problem, it's the camera

You don't need a 100A alternator in a Seven.

The Wosp can be adapted, but it's not a 1:1 replacement. Alan Bowler might know how it's done even without a multimeter and a wiring diagram.

If it wasn't for the fuzz about getting items sent from the UK....

You can always use brake cleaner to find air leaks.
Spray it around the inlet manifold / hoses. If revs go up, you have a leak.
Don't use it on the exhaust though. Then problem may be solved as the car will be written off in a fire!

Are you upgrading the Mazda Mr Flatters?

Just fit Time-serts in all the threads. Once done never any problems

Your effort keep impressing me Andrew ,-) Wish I had your skills!

That's absolutely correct. I searched for them but didn't find anything :-o

Mind you they are different from STACK-supplied switches
