Hello all,

I do have a question at the end if you want to skip the introduction.

My first stop was a tire shop to put on 7 new Firestone Transforce tires. I had read the horror stories about old tires with lots of tread left on them.
(bonus question, the PO had installed 245s instead of 225s which were recommended to me. They had both and I went with what was already on there. Did I get the wrong tires, overpay for wider tires I don't need, or luck out with an upgrade? I know nothing about tires)
<No problem there, some have reported interference at full lock, and some speedo error. They don't actually get you anything.>

So, here's the question I promised. Reading your responses to Gurr's post and his issues with maybe a fuel pump makes me wonder about an infrequent issue with the Portwagon. Two or three times, seemingly when the engine didn't turn over immediately, it dumped some fuel. Where from I know not. The first time it happened I put it down to my forgetfulness -- I forgot it was upgraded to EFI and i pumped the pedal a few times. Not that that explained anything to me. But then it happened when I tried starting with a low battery, twice. Each time it happened, it quit dumping fuel pretty quickly, didn't continue leaking while driving or stopped, and then didn't happen again. ???

Here's what you should know about me. I am not a mechanic. Shade tree or otherwise. When I was a young man I changed the automatic transmission in a '77 Triumph TR7 all by myself. Well, myself and a Haynes manual. But any dummy like me can follow those clear, step-by-step directions. I also changed alternators, brake pads, starters, etc. but only after someone told me what the problem was. I can change parts but I'm really pretty clueless about how it all works. I envy you guys with real mechanical aptitude. And I'm eager to do as much work on my motorhome myself as is practical, but I'm also eager to find a local resource who has some familiarity with GMCs for the jobs beyond my capabilities. i'm not far from Ken Frey but he is retiring, Jim Bounds and Steve Rourke are pretty distant. Any referrals would be welcome.

Thanks Matt, the EFI is an Electromotive Tec GT and without diving into the archives I’m fairly certain it is about ten years old.

The first time, after sitting in the barn for a month with only a couple of starts, it dumped fuel onto the ground in a puddle the size of a dinette table top and continued to drip until I got underway. It seemed to come from a bit passenger side of center under the engine. This was the occurrence when I forgot and pumped the pedal. Drove straight to the garage that did my state inspection and the dripping had stopped and repeated restarts produced no fuel. All was well until I Started it with a weak charge on the battery and it did it again. Not nearly as much fuel and it quickly stopped dripping. Repeated that way once more, again with a hardish start. Otherwise, no issues.
