Do you have the part number for the plastic thing holding the wire on the coolant level sensor?If you want the genuine part they are expensive. The part number is here.

I bought a metre of this Mocal fuel line and made my own up.

It's a much better spec than the OE rubber pipes. Just remove the plastic ends from the OE part and the plastic sleeve that joins them. Then cut to length and put the sleeving on. You need 4 clips as well I used 13-15mm

5 clips cost £3.30 so all in around £16

I've replaced these fuel lines before (twice!) with aftermarket hoses. The line closest to the charge pipe seems to crack and I assume it is heat related.
Do braided lines offer heat protection? Have you checked your lines aren't cracking under the braid?
Is a heat reflective sleave the answer?
braid is more mechanical protection than heat... still rubber underneath and the combination of heat drying out the rubber and the hose panting from pressure variations under boost will still age the lines... a heat wrap or some of the aluminium shielding to give air gap heat protection is a better approach ultimately...Thanks @<tuffty/>
I'd prefer braided lines if deemed suitable.
Otherwise would these in a suitable size work?
