diesel fumes

[Archive]

has anyone had trouble with excessive diesel smell inside their first gen, truck? i have a 93 and have a bad diesel smell inside the,when the vent is blowing,and really bad just after pulling a grade. does all the air for vents come from in front of the windshield, if so is there any way to stop the air from the engine compartment from entering the cab. there is no rubber stop inside the hood, at the closure and body is this normal... would it help to install a rubber seal in this area... . would it hurt???

I have noticed since my exhaust has come apart in front and behind the muffler, if the wind blows just right I smell it inside the truck.

Might want to check yours out for leaks? #ad

Never have had a problem with fumes... even with windows open... check that exhaust system... Good luck,

check for fuel leak at the fuel filter/fuel heater. the gasket above the fuel heater can leak.

Adding to Greg R. There is also a bleed screw just above the filter on the line to the inj. pump. This one weeps once and a while.
If its exhaust, just as everyone else said, check all the clamps and connections from the turbo to the muffler.

I had a slow drip at the housing joint on the injector pump. Tried to replace the O-ring myself, but ended up spending $325 to get pump rebuilt. That got rid of the smell until my supply fuel pump started leaking. Replaced it; no more fumes.
