smelly cab - The 1947 - Present Chevrolet & GMC Truck Message Board Network

76bonanza · 10-02-2005, 11:14 PM

My cab stinks like gas when it is full upon checking just after fueling looks like it is leaking from around the sending unit is this an easy fix? Also If I dont fill it full will it not leak out there?

Thanks

Yeah it is easy just unscrew the ring should have a bout 4 or so tabs on it and unlock it.You probabally need a new o-ring there,wouldn't hurt to put a new sock on the sending unit at this time either.

Or just remove the sock, why put a filter in the tank and make it a PITA to replace?
not filling it up all the way is a good thing to do untill you can fix it. it is probably venting into the air in the cab and you just don't quite notice it yet.

If that fails you can use one of these...

Actually, I had the same problem at one time (before teardown). I used Royal Pine air freshener to "mask" the smell. Believe it or not, it worked.

76bonanza · 10-03-2005, 07:52 AM

ok can I get this oring from autozone? also if I dont fill full will it stop leaking if the fuel is not up that high? About how much less will get level below sender?

76bonanza · 10-03-2005, 09:22 AM

also after looking at it I see the locking ring. If I tap that out is it the only thing holding the sending unit in? Thanks

67ChevyRedneck · 10-03-2005, 09:59 AM

Yes, it has been a while since I've had to do it, but you tap on the tabs (I use a flathead screwdriver and hammer) and the ring should turn until it reaches a point where it will come out of the slots. I believe it tuns counterclockwise to come off.

Light a match and see if the smell goes away.

I know panhandler62 is joking, but I really hope you are not smoking with this problem in the cab. That would be

Works with the Gas smells in my house

76bonanza · 10-03-2005, 12:12 PM

No I do not smoke. Does anyone know if I dont fill it up all the way it will not leak out of that unit right? This is the first time I noticed it in 3 weeks but it was the first time I fill it really full. Want to make sure it did not just start. Also I dont think the fumes are that bad they would ignite I see people smoking at the gas pump all the time.
But anyway. And were can I get this o-ring from?

Joe67 · 10-03-2005, 12:20 PM

Sounds like the best info is posted above on this one. Just a little maintenance is all you need

If you don't fill the tank full you not get as much splashing near the O-ring but you might continue to get some gasoline odor.

The complete repair can take as little as 5 minutes if you have the o-ring and can get your seat out of the way. Make sure the doors are open and the cab is well ventilated. Use a rubber mallet.

70 shorty · 10-03-2005, 12:44 PM

you can get one from Athey's (Bill is a vendor on this board), i'm not sure if autozone would have one or not, but it might be worth a try.

76bonanza · 10-03-2005, 01:44 PM

How can I get in touch with athey's or bill to get one? also do I have to remove the whole unit it is a new sending unit.

One other question I have a reciept were he got a new sending unit and tank but did not own the truck then could he have done it wrong or maybe reused the old o-ring? Cant believe It would leak already.

76bonanza · 10-03-2005, 02:22 PM

Ok got it from gmcpauls got new lock ring also just incase is this the only place it can leak from? What about the spot were the thing with the wire is no gasket there?
