how much fuel does it take to fill up a wedge? i can only get about 20.00gbp of petrol in at a time so need to fill up about every 100 miles, is this about right or is only 1 tank filling, have checked breather on tanks
thanks

Yeh I can only ever get 20 - £25 worth in my 400 at each fill.
But never entirely sure how much is left even though the gauge is indicating empty! But always play safe and refuel at first opportunity.
According to SH Bible I think its supposed to hold
60 ltrs.

Sounds like you're getting almost exactly half the expected capacity, and given the twin tanks I'd guess this is because you're only filling one tank.

You do get to a point where you have to start trickling the fuel in, but I'd have thought it was rather more than half full.
I'd be climbing underneath to see whether both tanks are plumbed in...

Check whether the swirl tank (that feeds from the bottom of the tanks and thus X-connects the tanks) is not mounted too high. There is a huge (2"?) pour-over cross-over hose between the tanks at the top but for whatever reason does seem to work.

There are also some older threads on this topic. Grady

Can usually put about £40 in the wedge, or about 9 - 10 gallons.

I replaced all the connecting hoses, and swirl pot years ago. also, if you use "fast flow" pumps, they put a lot of air with the fuel. this causes big problems and I find I have to allow the air to eacape in order to get more fuel in. also, when the fuel filler is virtually full, try rocking the car from side to side. this helps the air bubbles to escape, and more fuel in.

I was toying with the idea of twin tanks/ twin fillers, but couldnt be arsed with the modifications !

I can only get between £20 and £25 quid in mine as well, I'm sure my other wedges took more fuel than that...

The trick is not to trust the petrol gauge , I go on the premise if the needle is moving then there's fuel in there.
I've also ran mine dry once to establish how much it took to fill and how far I could go etc

it was 60Ltrs to fill and I had a good 20 miles of range AFTER the needle stopped moving, typically I can get around 180-200 miles out of a tankfull, more if I'm feeling brave and mine certainly ain't std.

When I replaced all the fuel hoses and swirl pot on my 400 I ran the fuel down until it was outside the red on the guage. Once I started to drain the tanks I got at least another 10 litres of fuel out!

If the car runs out of fuel is it likely to cause any damage?

I can get about £25 - £30 in tops from empty. Needle does its thing from Empty to full.

About the same in the 350 as well if memory serves.

No. People reckon that running the tank dry allows 'the sediment in the botom of the tank' to be drawn in, but the fuel filter should cope with it; and besides, if the sediment was that loose, why doesn't it get drawn in anyway?

On a related theme, each injector also has a fine mesh filter on its inlet, and debris in here can cause running problems that aren't rectified by fixing the usual suspects...

I can get 10 gallons in mine (early 350i) The guage reads accurately when the engine is cold, but starts lying after a few minutes. I can have 1/4 tank indicated which drops to nothing after 10 miles. Still plenty left though. Trust the reading soon after startup, anfd keep an eye on the odometer.

My fuel guage doesn't seem too accurate? It goes from 3/4 full to just above the red in 20 miles.

The most I have put in is £55 worth of optimax in one go (no there wasn't a puddle on the floor).

I can get £60 of unleaded in my Omega from near empty and that's 65 Litres, so I guess 60 Litres in the wedge is about right given the price difference?

Wee man.
