Yep, she got me again! Shoulda listened to ya Frank!
Truck was plugged in all day yesterday. Started last night one gp cycle no problem. White smoke for 5? minutes then clear. Idled on rear tank for 15 minutes or so then figured I'd switch to the front - idled on front tank for 15 minutes or so - no change in idle, idled fine, figured "F" it! I'm taking it out to clear ice tomorrow... I checked fuel filter this morning - almost full. down maybe an inch from the top. Got in, started up easy one gp cycle (plugged in all night)
Got it running down the highway, started getting surging. at about 8-9 miles of travel I switched to rear tank to see if it still surged and needle dropped to E, truck lost accel and I switched back to front tank. Truck sputtered back but never recovered. Made it another 2 miles before it quit for good, but in that time it continued to lose fuel (push pedal no response, deceleration). Coasted into gas station on stall.
The keys to this are: The rear tank was at almost 3/4 full when I got it home 3 days ago, front tank was about the same. So I guess last night in the 30-40 minutes of idling the FSV pumped all the fuel from the rear tank to the front. I switched from the rear tank to the front about halfway through idle last night. I noticed the front tank was over full this morning while warming up, but I'm parked on a hill and I hadn't run the front tank so I just assumed I was off a little on how much should be in there. It did get me thinking that something was up, but too late.
