Please forgive a poor diesel fitter.....the only two carb V8s I owned (briefly,long ago) had been re piped with electric pumps in engine bay.....

.....I have been asked about a pinhole fuel leak in "metal section" (quote from owner) of fuel pipe from tank to filter that sprays petrol when engine runs . Obviously this is a little undesirable . But it does suggest the in tank pump is working . Given the age of the engine I was assuming it was on carbs .

My problem is that my version of rave only gives the injection models info and that says the pipes in question are rubber hoses not metal pipe .

Can anyone point me to more info on this or tell me what the likely situation is ? I have no more info and have not seen the vehicle , an RRC .

I dont have any metal pipes on mine for fuel unless he means the piece that actually feeds the carbs in the engine bay ?

The way my last two were plumbed and yes before some smart arse comments the last one ran!

You have rubber hose, filter, pump, rubber hose, metal feed pipe to carbs

86 RRC could be a flapper??

EFi engines have steel everywhere apart from short rubber sections at the pump, filter and fuel rail.

Apart from mine which is 100% rubber hose, no more fuel spraying leaks! Muhahahahahahaa!

Just told it is an EFI engine and the section is definitely metal . Is this integral to the top of tank assembly or is there a union ? Can I get a hose directly from tank flange union to filter off the shelf ? Or cut the metal pipe , flare it and put a compression fitting in the gap ? Or replace the metal section like for like ?

My RAVE doesnt have EFI either...MPI , yes.

Advice and ballpark prices ? Part Nos ?

Just go to a local hydraulics supplier (we have a firm called Able Hydraulics local) and take the fuel tank fitting and filter fitting and tell him the length.

The fitting are non standard so all mine were double male adapters to get back to standard then standard loose nut female hose tails.

I did my whole car for 40 notes (cash) but it would have been £75 on a bill I think.

Even so, not expensive and very easy/rewarding.

Better option than the landy OEM then ? I take it the steel pipes are a weak point all round ?

Steel = rust, crack, break, bend, crush, cheap.

Rubber = unbreakable, almost impossible to damage, expensive.

Any ideas why LR chose steel and used rubber where necessary?

Probably a British Leyland parts bin issue....never make a part if theres one on another vehicle

Just the fact that steel is cheaper I reckon...

Also legislation MIGHT say you need solid fuel pipes, cos again no doubt braided brake lines throughout would be the better option but hugely more expensive than solid pipe.

Anyway , I went and looked at the RRC friday and bought it for a V favourable price with a great chassis , a fair body in matt NATO olive drab , an EP9 winch hardly ever used , split charge , winch bumper with fairleads , under engine HD belly plate , diff protector etc etc etc and towed it home . Some creative plumbing with high pressure fuel hose and double jubilees got it running , now to replace all the perished vacuum and breather tubes and work out why the brakes ae so low on the pedal . The clutch does seem rather to the left on the pedal too .

All the usual 30 year old (ish) RRC niggles - leaking tailgate , sagging roof liner (anyone got a liner out of a scrapper for me ?) and then its insurance and away ! Had all new HD springs and shocks OEM , 3 weeks ago and 12 months ticket .

So thanks guys , will repost in RRC section later .

Well if it needs solid lines , my old dads got a Sykes Picka flaring die kit so I will just make solid lines for the next MOT . However , it DID have steel pipe subs with and olive flare to rubber hose to join to the faulty steel section that must have been original ....

I'm not talking about road legality but type approval etc for new cars.

Mine has done 3 MOTS with rubber pipe no problem.

Fully legal to use rubber.

PROBABLY just a manufacturer penny pinch
