The visually very manky pump hoses from the V8 - probably original (40 years and 220k) as they have looked pretty-much like this during my 20 years and 100k. The slight staining at the end of the top hose only occurred during removal.

This type of clip was easy to cut through

Back in with new hoses and Jubilee clips - the latter Waxoyled to hopefully keep them corrosion-free.

A section from the original pump hose - the short blacker section on the right had been over the end of the pipe, the rest exposed to fuel. No reinforcing, and absolutely no cracking on the end or the inside and external surfaces, even slit and opened out like this.

20 year-old carb hose, radial cracks at the end but not extending under the clamps. Some evidence of circumferential damage where the end of the carb port has been, probably from the unsecured filter flapping about all that time (which was how it came to me). Apart from that no other traces of cracking inside or out.

V8 overflow hose replaced in my time but not carrying fuel only fumes, only noticed when that float valve happened to stick:

The same thing happened to Bee's carb hoses.

Bee's pump hose with the braiding removed. No sign of any deterioration, but unlike the carb hoses it does have markings - BS3212/1 seems to have a max temp of +60C, OK for pump hoses but a bit marginal for the engine compartment. Dated 1996 and fitted 1998:

I'd bought a new banjo to fit to the hose before I started to save messing about with the old one once removed if fuel started trickling out (it did!). But looking at the old banjo after cutting off the hose I noticed it is flat both sides, not recessed on one side as here. The bolt and fibre washer goes this side, with either another fibre washer or an O-ring (depending on pump type) on the other: Rimmer Bros

But I couldn't get this to seal despite using two fibre washers on the recessed side and tightening as hard as I could. Not dripping or running but shiny at the join from a tiny seep, presumably evaporating fast enough, but no smell in the garage. Eventually I reused the original banjo and it was immediately obvious that this was tightening progressively and sealed with only 'normal' pressure on the spanner. The banjo above tightened suddenly, i.e. even with two fibres washers it was too 'thin' for the banjo bolt and was bottoming in the pump thread. More info here.
