I have had one of these hoses with the unclamped red ends fitted since 1999 when it was changed during an engine rebuild and I have many images of the engine bays of other TR6's showing unclamped red ended hoses, in fact have a look on the TR5 forum and you will see that CP2 which is currently for sale at Sherwood Restorations also has one. Do I and others have a problem I guess that is the question that can't be answered unless we have our own pipes tested? Maybe I should replace mine anyway as it is now 22 years old but what would I replace it with? In the short term I am going to fit some pipe clips at least until someone comes back with a source of pressure tested hoses. Derek The unclamped ones are probably done like the old one we used a hacksaw on, to liberate the hose fitting. the ruptured new hose end seen to the left. Quote Link to post Share on other sites

RogerH Posted May 28, 2021 Report Share Posted May 28, 2021 Hi Folks, there is a great deal of background work going on from Rimmers, the manufacturers, the PQI team and others. The manufacturers may need some time to get a precise feel on this issue. So, don;t panic but do inspect your hoses before and after a trip (belt and braces) if you can set up a video camera on the pipe with an monitor on ther dashboard that would help (jesting ) Please keep post relevant to the directly to the issue in hand - otherwise the thread will be toooooo big to understand in the future Roger Quote Link to post Share on other sites
michaeldavis39 Posted May 28, 2021 Report Share Posted May 28, 2021 Sounds good Roger as this is a very serious safety issue- I am thankful that no lives have been lost- not everyone with a TR6 is in this forum but obviously the suppliers will issue recall notices to all customers thankfully.

Hi Michael, any recall would be based upon what the investigation outcome is. Even then I think a recall would be rather optimistic The best that could be hoped for would be a warning notice in the TR magazine and making the other clubs aware.should it be required.

Hi Michael, If you are looking for full traceability that would be rocket science to the likes of Rimmer. We are not in the Aero Space Industry. Its up to the customers to do the fault finding!!!!!

KiwiTR6 Posted May 28, 2021 Report Share Posted May 28, 2021 I checked and found that my car also has this particular part. We only have one supplier of ethanol mixed fuel here and I never use their stations so the only concern for me was the lack of clamps on the fittings. I have a set of Oetiker pliers so the problem was easily fixed by removing the hose at the MU, sliding on 2 x 20mm clamps and securing these in place. Quote Link to post Share on other sites
Mike C Posted May 29, 2021 Report Share Posted May 29, 2021 I've used two jubilee clamps with the heads spaced 180 degrees apart. Last time I checked the FS on the WP was better than 2. The important thing is to use hose that's both suitable for your fuel and a tight fit on the piping. Quote Link to post Share on other sites
BlairP Posted May 29, 2021 Report Share Posted May 29, 2021 Below are pics of my hose, which is like the faulty one in appearance, but which is stamp-labeled "Aeroquip FC596-06 AQP exceeds SAE 100R6." Some Internet research shows it withstands pressure of up to 350-400 PSI, so I've attached some stout Jubilee clips to the ends which I think should do the trick. That said, I too have the possibility of installing clamps like KiwiTR6 did above. Is one better than the other? Blair Quote Link to post Share on other sites

I know that Aeroquip manufacture a screw together fitting but it is not suitable for rubber but ok for PTFE tubing. I am not certain what the principle is of this fitting that has failed? Bruce. Like most hose manufactures/suppliers, Aeroquip do variety of hose end fittings; Push fit Reuseable Pallet swaged (one piece shown, 2 piece to NCB 174 also available) Their push fit is adequate, meeting the spec and demands of the application, IF the correct rubber wire braided or nylon braided hose is used Reuseables should only really be used with wire braided hose (1 wire 100R1 or 2 wire 100R2) The most reliable is pallet swaged, either 1 piece (shown) or 2 piece. Me I wouldn't use reuseable My knee jerk is to go pallet swaged, but, push fit have come on in the past 10 years, so, with investigation, I might be persuaded No hose end fitting should be reused, EVER Note; the push fit shown is Aeroquip, the others, generic, but, all are very similar Quote Link to post Share on other sites
Waldi Posted May 29, 2021 Report Share Posted May 29, 2021 SAE J100 is a specification for low pressure hydraulic oil hoses. It is also suitable for diesel, but not for bio-diesel. I could not find information it is suitable fro E5, let alone E10. So I doubt this is an acceptable hose for out application. Waldi Quote Link to post Share on other sites

Further to my thread to you I have read some of the spec. sheets on the internet and like you I am not certain that they can be used in petrol applications as the manufactures of these fittings do not seem to have a dedicated hose for petrol but do for other liquids ? One needs to have a conversation with their technical sales dept. which I will do next week. Bruce Quote Link to post Share on other sites
RogerH Posted May 29, 2021 Report Share Posted May 29, 2021 (edited) Hi Folks, you seem to be scare mongering. The investigation report has not been compiled yet from the manufacturer via Rimmer. The hose in question is rated at in excess of SAE 100/R6 what ever that means. Bearing in mind that that worst it will get is E5 in the UK at present and typically 0% Ethanol The manufacturer is a world class supplier/manufacturer of oil and petrol piping. Please do not get your knockers knickers in a twist until the final report is posted. Roger Edited May 29, 2021 by RogerH Quote Link to post Share on other sites

Hi AQP socketless; 250psi (17 bar) and -40°c to +150°c You can get the full Aeroquip hose catalogue as a pdf from www.eaton.com Wire braiding is over the inner rubber hose and under the rubber cover. Roger is right with regards fuel spec hose sae100R6, which has, I think, nylon braid, rather than wire Quote Link to post Share on other sites

Blair You might find the bleeed nipple hole is the same as the hose hole. In which case just move the bleed nipple. If not rotate the cylinder by 180 degrees.
