Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

7 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Attachment 23581 Hi All, I noticed that I was getting a fuel smell in my cabin when the heater was on. I checked the fuel pump sending unit and do see fuel on top of it. I've order a new sending unit and seal. Pelican's DIY show three hoses on the sending unit. Mine only has two. Am I missing one? I've circled where the missing one might go below. Thanks!

POST 2Original post

older cars have a return line, my 03 for example does not. You are experiencing a common problem where the plastic fuel nozzle on the level element ages and cracks and leaks. Good Luck

Quotes source post: 658755

Thanks for the heads up. The hoses were a pain to remove on the sending unit. One of my connectors was bad and would no longer hold onto a nipple. I was able to use a similar Dorman part. It's held up thus far. The seal wasn't too bad. I used a new one and used synthetic grease to lube it.

POST 6 / ORIGINAL POSTEROriginal post

Welp, that Dorman part doesn't hold too well. It came off after a few day. I've ordered a new fuel pump.
