Discontinued fuel filler neck for 2007 XC70

CharlieKz · Post by **CharlieKz** » 27 Jul 2026, 09:10

Volvo dealer service department diagnosed check engine code P0442.
Needs new fuel filler neck 30742329, but part discontinued and no aftermarket found.
Trying to figure out options and best next steps:
- wait for used 30742329 to surface
- find suitable replacement part
- have mechanic to fix fuel filler neck
- other?

In US (NY and Conn).

Details:
Check Engine light P0442
Code ECM dash 434C fuel tank system leakage and ECM 439C fuel tank system majorly present.
Performed fuel system test through Vita vehicle - failed tests.
Performed fault tracing with smoke machine found leak at fuel filler neck.

- That PN fits P2 S60, V70, XC70...

- Your options are:
1. eBay: search under let's say "2007 S60 fuel filler neck" and make sure you buy it
from a car in the SOUTH. Your problem is salt corrosion on the aluminum in the Northeast.

2. Local junk yard...but this job is no fun, crawling under the car at junk yard (safety issues).

Can you check this drawing and tell me which number the part is you are looking for? If it is the long filler hose, this drawing has a different part number for an 07 XC70. Maybe it is a Emissions code variant like for a CA car. I know that some of the older P2's had metal tanks for CA so perhaps different pipes too?

Erik gave me the heads up that somehow the link got missed. I have to put it down to senility!

Internet junkyard?

In the drawing it looks like number: 11 with 38, 42, 12.

Thanks for your quick response. I found one for sale on eBay from TX.

However, confirming the part fits a 2007 XC70 is a negative. What do you think?

call hollands pick-n-pull salvage in billerica MA, they can pull the part and ship it, they have lots of volvos.
Or go there and pull the part yourself, their prices are a lot lower than ebay, $20-30 at a guess.

What is the seventh digit in your VIN?

FCP's website isn't perfect but it is a lot easier to use for fitment compared to VIDA/DICE or calling the dealer parts department for an "old" car. If your VIN matches the compatibility list on the listing, you have a great lost of all the compatible Volvos. If it doesn't match then the prior comments about stainless steel fuel tanks will likely apply to your situation.
