Fuel hose routing

[jamieduff1981]

Hi folks.

I've enjoyed my Cerbera for 1 week following all those running problems which ruined all of last year. Today I found a split fuel hose on top of the engine. It's the hose which comes from the firewall area down the engine valley and in to the fuel cooler.



Obviously it's back off the road again until I sort this but am hugely pressed for time at the moment and am trying to finance a new business so can't write my usual blank cheques to a specialist.

I'd be grateful if someone could tell me:

A) Where it comes from (I would guess the fuel filter in the rear wheel arch?

B) How is it routed and is it accessible with the body on?

C) Do the fittings need to be reused? I haven't found anywhere that can just supply new hoses ready to fit which would be my preference.

Thanks all,

Jamie

Actually done some searching. Mine is a 99 so should have copper pipes. In theory this shouldn't be quite as bad as I was thinking. I'd rather leave the rest until body-off time or else it'll just never get driven at all.

The one you mention is the high pressure line that come from the fuel filter to the cooler.

Having just had lines made by Earls i have an adapter going from the original hardline (through the inside of the car) to the said hose.

easily accessible but may have to remove fuel rail to route it through the v

From bulkhead fitting to cooler hose
The two hardlines are high pressure feed and low pressure return.

Thanks Peter. Is this the other end of it then? (Just below the wiper motor, using rusty old chisel as a pointer)



It doesn't look as bad as I feared then. Still it sounds like I'm going to have to get one made?

Yeah that looks like it. Mines different again as it comes out of the centre of the bulkhead in line with the engine.

I would image yours to be longer then.

Remove it measure it and give Earls a ring or go to a hydraulics place and they will be able to make one up.

I have a late 4.5, 99 with lines same as Peter; centre of bulkhead level with the back of the starter, the lines are steel with a union for the feed and a flare and hose clip for the return. Quite a pig to get at.

Yeah I can image with the air boxes and hoses on. I done mine from underneath as the gearbox wasn't there making access easy.

The fuel return hoses is a stupid idea in its placing as the throttle link rubs on big throttle movements.

I had the line cable tied out the way before on the old lines.

Need check the bore at the copper pipes and the bore at the fuel cooler as the cooler tails are larger bore / flare.
I have a hose step up adapter on mine.

[jamieduff1981]

The fuel hoses just aren't that well thought through!

Peter, did Earls need your old hoses to make up that lovely set you just got?

I really don't want my car out of action again but if I'm taking the airboxes and hoses off again (something I actually don't mind too much now I have short induction) then I really ought to get the cam covers recoated. Argh - it's all time and money again though of which I have neither in excess at the moment.

I replaced mine with standard rubber fuel hose and clips. I reused the original heat shield, all in all a very cheap and easy fix. You can definitely feed the hose through without removing the fuel rail, but taking the airbox off is essential. I agree with Peter, the return line is far too close to the throttle linkage, ideally the pressure reg outlet would be angled rather than vertical.

[jamieduff1981]

Is there a swaged union at the firewall end? If it's just rubber hose I'll go to the Autosave 150 yards from my office front door in an hour when they open.

My recollection is that it's just a barbed end a bit like this

Ahh brilliant! You just made my day!
