I'm considering buying some Poly-Armour brake hoses for my P38.

They don't seem to list them by application, just by sizes and connectors.

Can anyone point me in the direction of some specifications (diameter, length etc) and any relevant terminology re: couplers/connections for a P38?
 
Why, whats wrong with the standard ones?

Back when I had the money to get other people to maintain my cars I decided if I'm paying £45/hr or more just for the labour I'd like to get the most bang for my buck and leave things better than standard.

When I got my RS2 it wandered and banged about due to shot bushes and dampers. It under-steered quite a bit (as they all do). Powerflex bushes and Bilstein B6s fitted at considerable expense it did none of these things (okay it still under-steered a bit, you cannae break the laws of physics, Captain). Yes you can argue the problems were due to wear and tear and standard parts might well have yielded a similar result but we all know that at some level all cars (even £50k Audis) are built to a budget, compromises are made. Manufacturers often favour quietness and comfort over precision while I am willing to sacrifice a little of the first for more of the second.

By contrast when I did the alternator on the P38 a while back I didn't pay £550 for an LR item I paid £140 for a pattern part because it's a loosened serpentine belt and two bolts if it turns out to be rubbish and I can buy three of these for the price of one genuine one (or pay twice as much for the next one) and still have change. On something this simple and non-safety critical I don't think the £550 one will have any significant benefits. I'm not a nitwit with more money than sense, but my philosophy differs (a little) from yours.

I know you are the voice of reason on here for "stock is best" and that my P38 "isn't an F1 car" but if I'm spending my hours and skinning my knuckles doing the work I like the idea of fitting a part which exceeds the quality fitted at the factory.

If they are the original pipes then they have lasted for 14 years so far. Are you thinking of keeping the car past 2028? Personally I cannot see why they need "upgrading" when the original are sufficient, but it's your money,go for it:)

Ok carry on. Play if you must.
 
I assume as everyone here uses LR part numbers I probably won't get an answer to my question? C'est la vie.

Don't suppose so you have a lot of measuring to do. Don't forget single flare double flare unions to look at as well. And terminal fit into anchor brackets. Maybe a long job.
