Fuel injector pipes


Recommended Posts

Changed out to Braided fuel lines to a mates TR5 and he always complained it was harder to start when hot. Ten years later fitted the nylon pipes to his and hot starting problems cleared. Is it a mirth or fact, no idea but worked in this case and he is a happy bunny now.

Also, did I read in a recent TR Action, that if your earth cable breaks between the engine and gearbox, it could use the braided fuel line and cause it to heat up, possibly not a great idea when there is fuel inside it.

thanks all, Rimmers have cofirmed that the Goodridge hoses are incorrectly labelled and certainly hose 4 is 6 inches shorter than the standard nylon one. they are being a little arsey saying that they will have to investigate etc but effectively the wrong parts have been supplied. They have offered to swop them for the nylon ones but even the nylon ones are not the same size as the original taken off.

I can get braided hoses made up locally for £120 all in but the hose is 1/4 inch which is slightly larger bore than the Goodridge.(I take on board all the negative comments etc but I have lost faith in the Rimmers supplied part)

Would having a larger bore to the injectors make a difference to the fueling??

Not the lines between Metering Unit and injectors - they are all connected to the engine, so same potential.     Suppose the line between M/U and fuel supply - mine is 'Aeroquip' and the rigid pipe from the boot is copper.     But more likely is the choke cable/wire, especially if the grommet in the bulkhead is lost.

Hi Mike

I'd forget braided and R........ and find a source of nylon/pvc pipe I'm sure someone will know where to get it from them pull/cutoff your old pipe and make yourself a new set not a hard job and you can have them any length you need.

Don't use larger bore hoses or you will be inviting all sorts of air lock and starting problems.

Follow the brown bible and it is not hard to do. Get the nylon piping from a trusted source and go for it. I have done it a number of times and works well.

Have a go nothing to loose and make your pipes in the length that looks good as well as practical.

Go on have a go!

And he has plenty of old pipe to practise his skill with.

Disappointing response from Rimmers… doesn’t inspire confidence does it?

I went to Pirtek in Liverpool today and they just scratched their head. I have left one pipe with them to investigate etc but now getting disheartened and will end up buying a set from one of the main players. Has anyone any joy with replacing them and where from please?

Hi Mike, that’s obviously very disappointing to have made a trio for nowt! I’ve never had them fail me but clearly they’ve failed you.

So have you given the TR Shop in London a call, if not I would ? Personally I’ve Always had good results from them for things I’ve needed.

Hi Mike, I had my l pipes replaced by Prestige Injection but they’ve now been taken over by TR Trader. Maybe give them a call. https://www.trtrader.com/parts-lists/Lucas-MKII-Petrol-Injection.htm

Hello Mike I purchased a set of pipes from TRGB due to mine having a lot of rub marks on them and they were getting thin but A couple of years later I had one of my injectors playing up after blowing it out with the airline and reassembling it ran fine but I couldn’t stop it leaking on the union so ended up replacing the injector and it’s been fine since all I’m saying is by replacing the pipes it may not Cure the problem

Personally Rimmer's are the last resort for anything and I suspect Moss will go the same way now they are part of Rimmer's.

Profit first customer service and quality parts last.

Did you deal with Tom (big Everton fan) or the older chap ? Tom is usually really good. I’ve had all sorts of lengths of pipe off him for various applications and a contribution to the Christmas fund goes down well rather than asking for a formal invoice etc.

They supplied me with some nylon pipe for my fuel pump assembly, but don’t know what diameter the injector lines are - they may not have it.

Another good source of expertise in the area is Montador Motors in Birkenhead. Stuart there is very experienced at Triumphs and built the odd EFI system etc. Maybe give him a call and have a chat and explain your issue.

I’d have thought your best bet is to buy a length of hose and cut to size for each injector. You can then get Pirtek to fit the ends if you can’t do it yourself. They have all sorts of crimping gear if you wanted them crimping on.

Found that Revington do a set with 4.8mm  internal diameter Teflon pipe. See if Pirtek can supply that size (and forget the braiding) https://www.revingtontr.com/product/rtr4107/name/hose-set-injector-s-s-tr5-6

Also, have a read of this thread
