Minor problems with LV TDCI Focus

[Franco Cozzo]

Hello guys, something I've noticed with my Focus.

When I fill her up, usually the fuel tank makes a psssh noise when you open the filler cap, but its not doing it anymore? Is the tank supposed to be pressurised?

My fuel usage seems to be up about .5L/100km according to the readout and I'm getting about 50km less out of the tank with the same driving and I feel like its down on power, it doesn't feel anywhere near as torquey as before.

Also the injector return line (clear plastic tube) the fuel looks this red tinge colour not the usual diesel green?

Car is showing no codes when I scanned it either.

Getting some odd little problems now.

No idea about colour (I thought they dyed the fuel-excise-exempt stuff red or something, but could be mis-remembering how that works?)

But as an experiment... I just opened the filler cap on my TDCi (was ~75% full) and no psssh. I've heard it on petrol but can't recall ever on diesel cars.

Could be variations in diesel fuel, for example (depending on where you are) it could be winter-blend diesel. But from what I've heard it shoudn't make that much difference.

Yeah agricultural diesel is red I think, but I've been getting it from the servo, I'm worried that maybe there might be something causing it to be this red tinge.

Interesting about the pssh noise, try it when you go to fill up mine used to do it all the time.
