Fuel filler pipe leaking ?

[MuckyPup]

This is just sodding typical.........
I hate rust, so i spent a while looking for a truck that wasn't rusty.
Anything else i can put up with
So today's aim of the day was;
Investigate fuel leak when filling up.
Remove child size centre silencer (the one that hangs below the chassis rails )
Investigate the non functioning rear difflock actuator

I don't know what this truck did in a previous life, but the body and chassis are basically rust free, but the axles are plastered with clay silt type mud and as rusty as old boat chains.
Fresh water boat launching ????

So.
Actuator scraped free of approx 1kg of mud and soaked in plus-gas
Recip saw dealt effectively with child size silencer and off-cut of 2.5" pipe press-ganged into action
Leaving the fuel leak.......
The filler pipe is so rusty its essentially porous

Anyone got one ?
Anyone know how it comes off ?
Looks easy, but then again i haven't got the wheel arch liner out yet [attachment=0:zd61l8yq]27022012763web.jpg[/attachment:zd61l8yq]
Hmmm, need to rethink the car-port..........

I hate to say this but i'm pretty sure you have to lift the body up off the chassis to change it

Hey that rhymes

As for the fuel leak i can't help you .
But as for the escort i can help you if you ever want to sell it

I think Joinerman is right about lifting the body but I'm sure I've read somewhere about someone who cut the new one in half to fit it and rejoined it with a piece of fuel proof hose and some hoseclips. It's certainly a fix I'd look at if my pipe needs replacing.

Whats it like ?
Is it a rotter?
Always had a soft spot for the MK4

Does having moobs class as having a feminine side ?

To replace the fuel pipe you really need to undo every body mount up to the driver's door on both sides and then you need to jack it off the chassis.

Obviously you can hack it up with the old reciprocating saw and bodge it with rubber hose and circlips.

In the past we have successfully cleaned the pipes up and patched with liquid metal.

Doing this job right now.
Where on the body is it safe to use as a jacking point (be it with a length of wood to distribute the load)?

How much space does the filler pipe need, I presume it comes across in an arc past the subframe... and then the pipe drops down slightly at the bend with the chassis near the wheel arch. Then the filler neck comes down in an arc in the wheel arch?

Have the truck on axle stands on the chassis atm, with rear axle, fuel tank and exhaust removed. So plenty access.

Only just seen this thread and either I have been taking drugs or the rest are talking complete crap. Lift the body off? What? Seriously?

I have had the whole fuel tank out recently, replaced the entire filler system from fuel flap to tank and fitted a sub tank as well. And never once needed to undo any body mounts or jack the vehicle up.

Sorry but I feel like I am trapped in some parallel universe. The filler pipe, metal bit, which does go like Swiss cheese, is just held into rubber at both ends by Jubilee clips. It goes over the rear chassis member. There's no subframe.

If you have the fuel tank out already and the axle I'm genuinely struggling to see the problem. We're talking about the pipe from the filler cap to the fuel tank??? I have to be missing something.

THIS thing?

Hi Chris,

Aye, that's the one.
Sorry I meant cross-member not subframe.
Do you by any chance have a body lift in already?
How did you manoeuvre the pipe out then?

I only had one jubilee clip at the rubber hose end (part # 77201A), The smaller pipe also connects to a rubber hose (part # 77201B) but the clip is toast. The part where you insert the fuel dispenser isn't attached to anything.

After taking the 2 bolts out that hold the pipe to the body I dropped the pipe from the fuel filler flap area then tried turning the pipe so that the two ends that fit into the rubber hoses come round in an arc but there's no way they are going to fit between the cross-member and the body. An inch or two will probably do it I'm guessing.

Nope, no body lift ajnabi.

Hmm, do you know I can't say how I did it, but I can assure that my body has never been lifted from the chassis that's for sure. My pipe was leaking like a sieve just where it turns from the filler to the tank just where it says 77201. It was full of pin holes. I have done so many jobs I can't recall them all. Getting it out is easy, just chop it up. Getting a new one in can't be hard. Just bend it. I really don't remember any issues at all with doing this. In fact I'd have to look under the truck to remind myself. So it can't have been that hard. If it's that tricky, just cut the new pipe in two and join it with a bit of hose. I would take the easy option rather than start jacking the body off the chassis. That's bonkers.

Repaired mine, where the two pipe (fill/vent) are welded together they rust, see the picture on my MUD thread post number 58, see link. http://forum.ih8mud.com/threads/my-lc-80-thread.365673/page-3

Easy to repair and a lot cheaper than the Toyota repair cost and no body off is not needed as per Chris's comments
