Well, I didn't fly pipeline at 7000', but my fuel turnarounds were typicaly under 20 minutes, often considerably under. I had one stop I'd call on unicom and the truck was waiting and ready as I taxied up. He'd fuel, I'd hand him my card, get a drink and pee, get back, check the tanks and caps, sign it and be gone in under 10 min. Is there some reason you had to climb and descend in the minimum forward distance? Not really defending the silliness of not allowing a fuel truck to be driven across the pavement to get to you (like nearly any other volunteer operated event, it becomes a moronathon when things actually require some thought), but "not making a stop" shouldn't really be a consideration for the reasons you gave. "Saving money" or "saving time" is the basis of thinking that gets people to run out of fuel while still airborne. When you fly GA you always need to consider that it will be expensive and if you pay a buck a gallon more for fuel here vs there, it's gonna cost an extra $30 or so in a 172. Man, you can't even take a date to the movies for $30, you can barely take yourself. Is it worth stressing over? You probably cost yourself 2-3 hrs of enjoyment dealing with getting fuel, what's your time worth? As for saving time, especially when we're talking under an hour even by your given rates, that's another thing you just need to forget about. It will take the time it takes, even if it's an extra day. If you have a schedule definitely have to meet, light GA really isn't a great way to travel. You have to be able to roll with the changes and not stress out over it. Light GA scheduling is a +/- 3 day thing. Most of the time you can make your schedule +/- 3 hrs, but you have to be ready to allow for 3 days, because those times will hit if you travel a lot by GA. Just because you can go IFR doesn't always mean you should.
