Late Facelift Diesel Single Pump Circuit Diagram
 

Would anyone have a diagram of the circuit for a late model facelift diesel with single in tank pump that they can share ?

I have reviewed the last RAVE for the facelift model but it shows twin pump set up, however there is a page in it that does show a single pump arrangement, however it is not specific about which model it is fitted too?

I believe it was simply a case of deleting the low-pressure UBP as a stronger lift-pump was fitted in tank, therefore the wiring is likely unchanged though the bit that runs to the UBP was probably deleted too.

I will dig out the photographs for you Gary ;)

What I will say apart from everything else that is different in regards to the pipework, there is a a pressure relief valve fitted to the later setup, designed to vent at 420Kpa.

There is no reference to the later setup in any version of RAVE :(

Brian :D

Or about 61psi in real money.

Or 420Kpa in T4 Speak

As it happens after manufacturing the relief valve, the spring pressure was calculated by compressing an assortment of small springs until coilbound on a set of kitchen scales, and multiplying the result by 24 accounting for the total area of the valve to give the rating in PSI

When everything was fitted back together, the T4 live data showed a LP reading of 425Kpa or 61.64 PSI, near enough for pit work :cool:

Brian :D

Brian, any luck with digging them out ?

Been busy in Barton upon Humber Gary, I will have a sift through for you ;)

Brian :D

Noticed a diesel smell and looking under the bonnet of my 05 diesel Tourer i can see a leak around what appears to be an inline valve on a fuel line below the filter. Does anybody have a diagram of this set-up please? Bit dark at the minute to be faffing about...
Thanks in advance.

HI Joe.
I don't have a diagram but have a photo of this one way valve on the fuel line, below and on the side of the battery, they can sometimes leak, of stop working.

It is a Pierburg canister. I have never been able to find pin down a part number for it.

This is the only one i found ages ago 7.20235.03.0 and 7.202235.01.0 last one is for an Audi ?

This is not relevant to what the OP original asked for mind.

Appreciate your picture Steve, that is the valve I mentioned. In daylight it was diesel leaking at the front fuel line connection to this and when I removed the clip it could be seen that the pipe was a bit chewed where the clip had been. I have replaced the trimmed pipe and secured with a new fuel clip which appears to have done the job- a wee run out and the paper towel wrapped around joints shows no signs of diesel.

Was asking for a diagram in the hope that part numbers for all pipe sections/ clips / joints and the valve would be shown, making finding replacements easier.
