Aye it is a fomoco filter, but it wasn't fitted by fomoco, im trying to figure out if it was changed in 07 as the receipts(Fred in the Shed receipt) suggest or if its older!

It starts fine, just doesn't rev after 5 or 6 miles. I forgot to mention that when I popped the hoses of the filter there was no spray or evidence of "stored" fuel pressure :(

Well I wouldn let that confuse u ur issue only when warm u said drives grand until engine gets hot an then don't rev now fuel filter can have some issues on drivability but i don't think a filter would would cause ur issue but I could be wrong like I had focus years wouldn rev over 3000rpm when I drove car with fuel pressure gauge on pressure would drop a lot replaced pump an problem solved

Yea I know what you mean, I guess I'm just hoping that it's cured but I have a nasty feeling it is the pump as you say :(

I'll know in the next few days when I start driving it again.

No! Defo not. Just looked at the container again and now that a lot if the fuel has evaporated off it almost looks like a fine sand that has been left behind

Just took it for a short hard run, took it to 6k rpm in every gear to put as much pressure as I could and no hiccups do far, though that said it was 90miles I covered after the last long period of rest before it did it, so I'm not getting my hopes up!

No experience myself but I have read that this is a failing fuel pump.

The 1/4 tank bit was mentioned - but can't remember where I read it.

most likely a pump problem, but could also be water in tank, as water will sit at bottom of tank so lower the fuel more likely to be sucking up water....just a thought
