Irritated...fuel smell in cabin

By BLaCkSiLo
- Wed Sep 02, 2009 4:20 am #141151 alright, so i recently went turbo, using the DSM 450cc injectors with the stock (replacement) seals. they were leaking for the last week or so, so today i took out the injectors and replaced the seals, both the bottom and top (rail side) o-rings. it reduced the smell a lot but not all the way and it's noticeable at idle with the fresh air button pushed on the HVAC controls. it's pretty annoying and i need to find the problem, i don't really think it smells like the exhaust :? .... but close?

so did i mess up again or is there a possibility of smell elsewhere? I'm running a full exhaust and no open DP, i do have a vented catch can in the corner where the stock intake box would be. is there a trick with the 450's?


thanks for any assistance.

hmm, alright, i will double check all my charge pipes and stuff, i did re-tighten the DP last night but it wasn't loose. i actually did put some grease on the bottom butt seals to make it easier. maybe i'll have to try it again :?

no, i didn't eliminate the box, that's the one with the lines that go to the evap solenoid on the IM right? (and somewhere else, i can't remember). i highly doubt it's from my fuel pump install because i ran the walbro when i was N/A for about 2 weeks and it comes through the air vents when selected on fresh air. i don't mind the smell coming out the ass but not in the cabin, lol

the return line isn't leaking and i can't find any fuel actually anywhere on the IM or anywhere with the lines/filter/banjo bolt...so who knows, thanks!

If you take a shit in the sink, don't come and ask us what the smell is.

do you have a better idea other than a sealed unit with a slash cut in the exhaust? and the only reason i asked is because the smell was there BEFORE the catch can and the catch can is by the headlight.

as i stated before, i wanted to know if there was anything else i should look at and not to get dick responses.



thanks one dude, i will check that out :thumb:

Just saying...
