Well, Dave, if you read this, I should've asked for advice
before I put 5gal of fuel in it. I have an "L" shaped driveway. The entrance is @ a downward slope & the short area toward the garage is flat. Heavy's parked in front of the garage door where it's flat & since I've been using the Tank, it's parked @ the entrance.........on the decline. So I guess the angle it was parked kept the fuel from leaking @ an amount I couldn't see when I went to work. I drive to work & parked it in my usual parking spot........where it's flat

.
I come back from my deliveries & work the dock for about an hour or so & one of my co-workers comes up to me & tells me there's fuel all around my truck, @ least a couple of gallons. I thought he was talking about my Sterling because I had a leak a little while ago from a bad fuel cap, so I ran outside to have a look. It was bone dry everywhere.............then.............it dawned on me.........& I got that terrible hot feeling around my face & a bad tingle that ran from my back to the top of my buttcrack. I was coming to a horrible realization of what it was. I walked back to the building & my boss said it was OK to punch out. I did that, grabbed my chit, & ran outside.
Yup. There it was. A nice puddle of fuel going back to my rear fuel tank, & it ran under the Ranger of the co-worker who told me about the spill. I went back inside & told my boss about it. I grabbed the kitty litter & shoveled a crapload all over the mess. I went back in & told my boss why this had happened & he was cool about it & said he'd have one of the dock workers shovel it up in a little bit, just to let the litter absorb for awhile.
Pissed; I drove back home & just as the headlights hit the driveway as I was pulling in, I saw a small puddle of fuel right where the Tank was sitting.
There you have it. Looks like I'll not only need a radiator, exhaust, parking brake cables, & oil/fuel filter. Chalk up a rear fuel tank to the never ending list of chit I gotta fix. HOW MUCH DO I LOVE MY IDI???
