Delica L300 Power Steering Hose Return Tube Corrosion

My much loved Delica L300 has lots of corrosion on the under side - its almost at the point of no return.

The Power Steering Metal Return Hoses have now corroded through along with the driver side Oil Cooling Radiator Unit. Its now off the road.

Most of the bolts and connectors are completely seized and its going to be very difficult to get them off and replace them.

I've taken the Delica to our local garage, who have worked on it in the past; they say that they can't help.

I don't have the skills or equipment to do it myself - So what should I do?

1) Sell the wagon as is and let someone take it on as a project
2) Try and find the parts and a garage who are put to a challenge

Any help and advice would be much appreciated

I do have some photos but as I'm a newbie the system doesn't allow me to post them...

Hi, surfwagon. You can pretty much do without that radiator, unless you're doing a lot of twisty driving in mediterranean+ heat. When mine burst, I simply connected the 2 rubber hoses with a length of 8 or 10mm microbore central heating pipe, until I found a suitable rad off an Isuzu Trooper at a scrappers. Not a perfect fit, but is held in place with wire and brackets! When the steering pipe started leaking, right at the joint which is bracketed to the bottom of the chassis, I managed to fix it with a suitably sized plumbers compression fitting. I could have used 2 fittings and a length of pipe, but rust was limited to close proximity to the bracket, so I simply re-bent the pipe loop at the front to make up the difference - only an inch or 2. NB plumbers pipe is not rated to the max pressures of your steering pump, so try not to be turning the wheels while static, especially when against a kerb or other resistance. Or get a good piece of steel pipe from a scrapper.

Having joined the club five years ago, in 2013, your definitely not a Newbie  :D ; you just haven't posted enough times to allow posted external links to show.

The pipes are shown in L300 FAQs section of this forum, Section 37, pages 42&43 of Pink Pig's downloadable manual. No part numbers on there but Lewis may be able to find them.

Hi,

I recently repaired my power steering line in the same place (Thanks Andyman for the tips)

I first cut the pipe either side of the chassis rail
Cleaned the ends of the pipes with wire wool, then cleaned again with power steering fluid and a cloth
Used two 8mm compression fittings - you may want to double check the pipe size as mine is an old 88 pre-face lift
https://www.screwfix.com/p/straight-coupling-8mm-x-8mm/20317?tc=CA7&ds_kid=92700020969714541&ds_rl=1248151&ds_rl=1245250&ds_rl=1247848&gclid=CjwKCAjwzoDXBRBbEiwAGZRIeBkKmP29Kaz0bFJQWgnA1VXskZ2t0n-l_8GoNbXvF0EuodtIvlCe-BoCcIMQAvD_BwE&gclsrc=aw.ds&dclid=CMny3uGg1doCFUw4GwodOtQByQ

and then used a short length of 8mm steel tube like this
https://www.metals4u.co.uk/mild-steel/c6/tube/c2239/tube/c56/8mm-dia-x-1mm-hydraulic/p9134

Probably took 2 hours, but mostly because it was freezing mid-winter so more tea breaks than work!
Reckon somewhere that does brake line repairs could do it in under an hour.

Thanks for the information. I've been trying to find the parts so making the tubes looks like a good option.

Lovely looking van. I am thinking you might need repairs to both pipes while you are on. That bracket/joint appears to be the cause of the rot, trapping salty road muck, and wrapping a corrosive poultice around the pipes.

Hiya surfwagon did you manage to get this leak on your power steering  fixed I have the exact same leak on mine just noticed it yesterday. Did you find out the part number of these pipes or did you just go with a diy fix... Any help on how you fixed it would be appreciated. Was supposed to take the wagon away this weekend but didn't want to go anywhere until I sorted that leak out

We've managed to find a local mechanic who fixes farm vehicles who removed the tubes. We had some new flexible tubes made up by South Coast Hydraulics for £50 each - reusing the end connectors

The mechanic is now fitting the new tubes.

If you check out my profile link you can see what the new tubes look like. Now all we need to do is replace the old gearbox oil cooler unit, replace the fan belts, fix the handbrake, fix a few rust spots and find the leak in the front cabin.

Once all that is done we should be good to go!!

Wow super job surfwagon. The new power steering pipes look the job. I Might have to try something like this with sorry looking pipes. Hopefully you get the rest of the work sorted soon and you are back on the road. Keep the pics coming👍👍

Good fix - might have to do the same to mine at some point.

Where there's a will, there's a way! Never thought of using flexi hydraulic pipes, but why not? Rot proof, and ultimately more reliable than cheapo steel!

surfwagon, any chance you could post those photos of your power steering flexi-pipe fix back on here or somewhere else?
Would be super useful to see - I need some more permanent fix to mine at some point, but unfortunately the link to your website above no longer seems to work... Sad
