Td5 fuel hose to the front of the engine block

**jbe** · 22nd February 2018, 04:43 PM

I just replaced my Td5 fuel pressure regulator last week. The hose that goes to the front of the engine block was in very good nick and so I didn't replace it.

However, after having a close look at it, I was wondering if there is a special tool needed to undo the nut at the front. It is a very tight space and I can't see how I would get there with a standard spanner. Or, does the intake manifold need to be removed to get the hose off the block.

Cheers

I managed to undo mine without taking off the inlet manifold. Battery box etc came out. Others have gone the inlet removal route.

I cut the pipe leaving enough of it to slide a hose over it and clamp it.
from my research, it's the return line, so not under any pressure(very little is any)
I left a longer length of the pipe just in case a single clamp wasn't enough, and a second clamp may have been needed.
On the hose itself, I cut at a point along the pip section removing the clamped hose, and used some good quality fuel hose at that end as well.

A few thousand klm later and the single clamp holds it just fine.

Once you cut the pipe, you just need a long enough (deep socket) .. making the job 'easy as'.

To cut the pipe I used a bolt cutter, which obviously compressed the pipe a little, but was easy to get it back into shape. Filed the cut end to remove all burring so it didn't damage the hose when fitting up, and whilst remodeling the pipe, made an ever so slight flare as well. Not much, just enough to make it hold the hose a bit better once the clamp was done up.

I can go get a photo if you like, but I don't really want to remove the hose or fitting today .. almost certain to start raining the moment I start removing something!

(D2 TD5 is my brothers, but I have it here ATM doing some other stuff too)

One of the little tweaks I've had in mind to do, to neaten it all up, is to redo the head fitting with a quick connect end, and make one up for the FPR fitting as well.
So the plan is to eventually fit a hose with both ends having quick connects, and remove the hose easily from the FPR to the head(instead of using the hose that comes with the entire FPR assembly.

The return line is another example of lazy arsed, half witted engineering by LR people.
That 'pipe and hose' really needed to be a quick connect hose from the beginning.

Sorry! I told fibs(a little).

Initially I fitted it up the cut pipe as described, but I just remembered that the nut that screws into the block was all chewed up, and may have caused trouble if it needed to be removed, so we changed it early on just after we did that.
The straight bit of pipe coming off the FPR has the same thread as the nut at the head, so we replaced the cut and reformed pipe with the old quick connect pipe from the old FPR.
Fits perfectly, but a very deep socket was needed, and even that wasn't deep enough. The 3/8th drive had to be half fitted onto the socket end as the pipe fouled it. Didn't require a lot of torque to fit, so was confident that the half inserted square drive on the socket end had enough bite in the socket not to slip when tightening it up.

So I already have a quick connect fitting on that pipe coming out of the head and the hose with clamp holds up fine on that too.
