Depression Hose

[shed_racing 0]

Hi All,

 

In the process of replacing the starter, I removed the air inlet manifold (don't ask . . . ) and in doing so took off the little rubber hose that runs from the the inlet manifold, then 90 degrees to the fuel pressure regulator at the RH end of the fuel rail.

 

It's part #1622.83, termed Depression hose - it's about 100mm long, and something like 6mm diameter. There's no clips to hold it on, it's just pushed on at both ends.

 

Depression ?! I should say - I just went to order one from the main stealer, and they wanted small change from £20 !!! (£18.70-something) The fella in the parts dept. didn't appreciate my incedulous laugh, and strangely didn't seem too keen on dropping the price or haggling when I pointed out that it was a little bit of rubber pipe, with no special mouldings or features.

 

My question is, could I use a fuel/oil rated alternative from the local motor factor ? It doesn't appear to be high pressure, although I'll add some retaining clips at either end to be sure . . .

 

Despite the fact that it looks to be original, in that it's gone a bit hard and brittle, I'm kinda regretting taking Mr. Stan Lee to it. (although the manifold is now squeaky clean, inside and out, and the injectors are VERY excited, as they're off for a family holiday and a refurb)

 

Be grateful for your thoughts,

 

Thanks !

just get a cheaper piece of silicone hose

It's only a vacuum line for controlling the fuel pressure - so pretty much any rubber hose will do.

 

Take the old hose to a motor factors and ask for something the same size. Shouldn't be more that £3.

Thanks guys - I had hoped as much !!

 

Got a nice bit of shiney black silicone vac hose from when I replaced the dump valve on the SAAB "Thank you sir - that'll do nicely"

 

Couldn't believe that price . . in fairness, he did say that I MIGHT get more than the 100mm I needed, but then then again, I might not.

 

He didn't, however, suggest that I'd get 10+ meteres of the stuff, which is what I'd expect for twenty quid.

 

Thanks again for the quick reply chaps - just got to wait for the postie to turn up with the starter, and I'm good to go.

why did you disconnect the depression hose when removing the inlet manifold ?

To remove the fuel rail to get the injectors out for refurb?

 

Anywhoo Shed, how did it all go? I've got a lovely 306 gti-6 starter motor here to go into my 8V and I was planning on doing a very similar thing - taking the inlet mani off to get to the starter. Any pitfall along the way/top tips to share? I know that the starter can be changed by removing the rad but I can't be arsed dropping the coolant and taking the front of the car off, unless it turns out you had a nightmare doing it.

the starter can be changed from underneath which is quite easy if you just move the oil hoses out of the way. no need to remove rad

 

it should be a doddle with the smaller gti6 starter

As already said that pipe is a vacuum pipe and its supposed to be hard so it doesnt suck closed under vacuum,you could replace it with another piece of pipe but make sure that its a hard pipe.You wont need any jubilee clips on it either.im pretty sure I have one of these pipes at work,if your interested then pm me and ill have a look for it.

maybe on one of your big ol' 309s but it's bloody tight in the 205 bay! I'll give it another look though, although i dare say it's skinned knuckles time again...

i wouldn't of suggested it if i hadn't previously done it on the 205 gti i used to have

Damnit, no excuses now...

Thanks for the comments gents - this has turned into one of those domino jobs; you start one, and in order to do it, you have to do another, and once you started the second one, there's a third. . . . .

 

I've ended up recon-ing the injectors and cleaning/polishing the inlet manifold to within an inch of it's life among many other things.

 

I did a search on starter motors (after initially screwing up and not looking in previous years !) and a couple of threads agreed that you could get it out without removing the manifold or the rad - truth be told, I tried that, and got so frustrated that the manifold had to come off; I'm not sure if those people had fingers like ET, (longer, with at least two more knuckles than mine) or employed David Copperfield, but I really cannot see how they did it - there is insufficient room under the throttle body, and with that chuffin' great bracket on the back of an original-sized starter, you can't even get it out past the alternator. Magic and trickery is the only viable solution !!

 

In the biting wind with a headtorch, the manifold simply had to go . . .

 

 

Thanks for the offer of the pipe, pugdamo - I've managed to get hold of a suitable replacement. Very kind, though.

 

 

Well, I managed to persuade the remainder of the gasket to leave the head this afternoon, and it's all ready to receive the recon 1.1kW one that's due here on Tuesday.

 

 

Oh, and if it STILL doesn't start after all of this, I'm removing my CD player and giving the car a Viking funeral - it's the kindest thing.

 

Thanks again chaps.

Sorry - just read back - Shalmaneser: Drop the coolant !!! Pulling the inlet manifold means taking off the old gasket - pigging nightmare. Think mine may have been the original, and it stuck to the manifold ONLY in the vicinity of the injectors, and ONLY to the head around the blanked-off cooling holes.

 

Seriously, if these fellas convince you it's possible to do it without removing the rad or manifold, try it. Or get David's (Copperfield) mobile number and get him to do it !

 

Your patience must be infinitely greater than mine, chaps !

 

Bound to be cheaper to pull the rad . . . although a new mani gasket, plus 4 injector seals still saw change from £20 at the stealers . . how much is a litre of antifreeze in comparison ?

 

Knuckles have dried and cracked, so the traditional blood sacrifice to the car gods happens each time I bend my fingers now - even typing hurts !

 

The very best of luch to you, sir.
