Can someone identify this pipe?

[TheSvamp]

Hi all,

Recently bought my first volvo, an 05 S60 2.0T

Can anyone tell me what this tube (the clear plastic one) is meant to be, its connected at the intake manifold and to a T piece which is connected to an air pipe somewhere near the turbo.

I'm guessing it isn't standard and the pipe has collapsed.

Can I replace it with a similar rubber pipe with the same internal diameter from Halfords?

Thanks

May be a vacuum pipe ? It also looks as if it's possibly collapsed ?

The other rubber pipes attached to the same "T" connector look perished, probably why you have a replacement, clear, pipe. The jubilee clip also looks loose ?

my guess would be vacuum as well and if that's the case then any type of tubing will do as long as the diameter is the same as you say

the light grey piece appears to be a one way valve for some reason

personally Id save myself the trip and order tubing next day delivery on amazon but whatever you prefer

as mentioned above the other bits look half dead as well might as well replace them at the same time

those plastic parts can get brittle so careful not to snap when pulling off, pushing on (I assume it's probably just a resistance fit / barbed end) or just order a 3 way connector ahead of time and replace like this but obviously the right diameter

make sure it's cable tied well clear of any hot or moving parts

Thanks both for your help.

I'll get on to replacing those perished pipes. Just wanted to make sure I wasn't missing anything.

That doesn't look like the original pipe anyway, you can get the proper stuff and cut it to size at motor factors and maybe Halfords too, just make sure it's the correct bore size so take the T junction with you to size up.

Hi,

That's part of the fuel evap system. What you have there is the special mod done by Botchit and Scarper.

I've attached a picture of what it should look like.

The grey 'doughnuts' are imortant non return valves. My guess is you're missing the one between the T and the turbo intake hose.

The tube is quite fat compared to the rest of the vacuum lines but I don't have the internal diameter to hand unfortunately. FRF Swansea will be able to help as always.

1) Big affirmative on replacing the entire pipe assembly. EVAP codes can drive a person mad.

2) Unless the design of the EVAP system has changed, there's a soft (oddly soft) rubber "J-hose" which runs aside the charcoal canister. They can split and leak too.
It's contours (the J) are simply to allow said hose to hug the outside of the canister. It's only about a foot long. and cost me $21 at a dealership ~10 years ago.
NOTES on that:
a: You must remove the LR fender liner to access it.
b: Since there is no specific code for that specific hose -translation: you won't know which hose section is leaking- I attached a piece of scrap garden hose to the air intake of the fuel filler pipe and blew into it.
The resulting hiss came from my bad J-hose.
That may sound crazy to some but it was an immediate detection method which saved a lot of time. I'm still patting myself on the back for coming up with that one.

3) A fellow told me those EVAP hoses are big because the designers wanted to be able to provide more airflow to the system in order to dry out the canister if it gets flooded.
Do not with coax fuel all the way up to the top of the fill neck.

I learned the hard way after brimming my tank before a long trip. I forget the codes I got but the system cleared itself out by keeping the fuel gauge at or below 3/4 for a few days.
Thank goodness I was on a long trip in a populated region with lots of gas stations.
Ironically, I relearned the lesson when my brother brimmed my tank before a trip (I had walked away). The effect and clear-out time line was the same so it's a "repeatable experiment" Ha-ha.

I type all this because you just got the car and might not know.

Also, assuming you have an automatic transmission, perform at least one transmission fluid drain and fill to see the condition. For very little effort and the cost of 4l of fluid you can more intelligently decide how to proceed.

Thanks again for the replies and the info about the fuel evap system.

I've got no codes for the system but I just thought the garden hose was a bit on the weird side.

I've pulled most of the hoses out now and the solid plastic pieces look OK so I might just grab some silicon hose off amazon. ID is 8mm I think.

Also, the transmission fluid is on the list of things to check/replace along with the pcv system and a suspension squeak from the top shock mount... and a radio issue... and an electric chair issue... and it needs a general service. But I got the car for relatively cheap so it is what it is.
