Got the petrol injectors on all cleaned, I may need new seals soon, petrol pipes are on. & I've had my new starter motor back from Shorts where it was re-coned
I've just removed my petrol tank & look what I found:-

These aare the pipes on top of the tank, very cracked & very perished & couldn't get to the bin quick enough.

This one is very very dodgy, it ripped as soon as I pulled it. Its probably 30 years old & is the original. Its tucked up above the leisure battery nearside. Up in the vent, easy to get to but hard to see.
My advice is to change all these ASAP.
