Changing low pressure power steering hoses

[nigelj77]

Hi folks,

I'm looking to change the low pressure hoses on my 2000 griffith 500 and would appreciate some advice on hose size and lengths.

I've measured as best as I can get in and where they leave the reservoir and they appear to be 2 different diameters, one approx 25mm one 20mm, does this sound about right, maybe 5/8" an 1/2" bore?

Confirmation of diameters and total length of each would be appreciated.

Thanks,

Nigel

I've recently had PAS fitted to my 1997 Griff 500.

I manged to find a used complete system off a Chimaera. The hoses were not the best due to age. I asked Andy at Specialist Sports Cars, if he could fit the system while the car was in for service and MOT. He had a complete PAS hose kit ready to go on the shelf. Might be worth a call.

Thanks Yatesy350i, I think I've seen his kits online, I believe i only need the low pressure hoses which should be fairly inexpensive as they don't have swaged on ends, I'll just need to try and get an accurate measurement. Motaclan from memory supply the hoses and are fairly knowledgeable but knowing TVR nothing is ever "standard"...

This is the kit I believe:

My Griff had old, original lines that were leaking, so Andy fitted this upgraded kit for me in 2023.

The large hose is 16mm - 5/8" the small hose is 12mm IIRC not 13mm - 1/2"

Thanks all for the info.

Sardonicus, that's the information I was looking for, obviously hard to measure the bore without disassembly and i reckon what I've measured externally sounds about the sizes you suggest.

Will let you know how I get on, I've roped in a rally mechanic mate to give me a hand.

Hi folks,

I said I'd update on how I got on with swapping my hoses and am only just getting round to doing that.

Having been told by a supplier that both hoses were half inch that's what I ordered only to be disappointed....

On removing the reservoir it was clear I needed 1/2" and 5/8" as informed by Sardonicus so half way through the job I was stuck.

Thankfully a local branch of Pirtek supplied the 5/8" I needed.

To anyone having a go at this job it's diy doable, I made a plug the fasten the new hose to the old to help feeding it through. It took me about 3 hours some of which was fighting with the wrong hose, I used less than a meter of 5/8" and less than 2 meters of 1/2" and about a litre of the correct fluid, I also used new clips rather than have snow old one fail on refitting.

I hope this helps someone else.

Cheers Nigel
