I have replaced most if not all the fuel lines on the coach but I seem to smell diesel when the tank is totally full only.
Is there a vent somewhere in my 97's tank? Or while I see no visible fuel on the outside of the tank on either side can the caps be the issue? Only reason I ask versus pressure testing the tank to 10psi is has someone already figured this out?
Thanks. Bob
I thing if you PSI test your tank to 10 PSI you will be putting 82,080 pounds of pressure on It , and it will try to go round. Gam
Bob,
On our '97 the fuel tank vent comes off the right hand side of the tank above the fill neck. It has a check valve at the tank to keep the fuel from sloshing out then the vent hose runs through the front bulkhead and dead ends almost in the center of the coach just above the front bulkhead bolts.

On mine the breather tube is connected on the top of the tank near the passenger side, than runs forward across the top of the propane tank, through the bulkhead and down the front of the bulkhead just behind the front tires.
I have spilled diesel accidently when filling and the smell lingers for days or weeks. I removed everything and power washed the compartment to get rid of the smell.
Run your finger around the filler tube to see if cap is weeping, or look for a dirty spot.
I believe it would be dangerous to put 10psi in your tank, perhaps a few ounces.
See I knew the info was here
I smell diesel fuel inside when I fill up at truck stops. Finally figured out that they spill so much that it is my shoes that smell. Wash em off before you track it all over.

It doesn't take a lot. Just spill a 8 oz. jar onto blacktop and see how far it spreads. The spill the same amount of gasoline in a different spot. I'd swear the diesel spreads four times as far in area. So that is that much larger of a area you can end up walking in.
That would be too easy.

I've often found the smell gets on my hands after filling up due to a dirty nozzle. Even after washing my hands the smell is still there. I've discovered that using a generous amount of hand lotion after washing and then wiping the lotion off with a paper towel does the trick.
I spoke to FOT "Lyle Reed" about this issue on my coach .Found out that all vehicles have a ball check valve at the top of each tank . Reason being it is required by US DOT to prevent fuel spills in the event of a wreck resulting in being turned over. If you fill your tank to the very top of your fill neck , this will result in a small amount of fuel coming out this ball check valve while sloshing around .The fix is do not fill to the neck . This ended this issue for my coach . Brad Metzger
