Fuel tank to pump hose

[James McGrath]

Does anyone know the diameter of the fuel hose that goes from the tank to the fuel pump? Mine has started to weep.
It's on my 1990 20NE cavalier, so the fuel pump is external.

The part mumber is 90325858. One is avalable for £25 on ebay but I thought that was a bit steep for a hose that probably isn't E10 petrol compliant.

Thought I'd just buy some generic fuel line but van't find the diameter anywhere.
It's quite a lot bigger than the other 7.3mm lines.

Looking at the related fuel pump part no,
It appears that the pump is 12mm input and 8mm output.
So allowing for a snug fit, you are looking for approx 11.5mm internal diameter / bore.

Thanks Rob, you're a star.

Hose ordered!

Just for future reference, I used a 12mm hose as I couldn't find an 11.5mm one.
Fitted perfectly but a note of warning, it's longer than it looks. I bought 90cm thinking that it would be plenty but it only just fitted on. An inch shorter and it wouldn't have gone on.
So you really need a full meter of 12 or 11.5mm internal diameter hose.

I changed my hose a few years back and our local parts store would only sell it in lengths that were miles too short (he said something about elf and safety?!)
Ended up buying 2 and had to put a join in it.
