I had little trouble with the plug, but the real PITA was the fuel line next to the plug. I could not get the quick connect squeezed far enough for it to let loose. I ended up coming in from the driveshaft side, squeezing up in beside so I could get my hand in that way, then have my girlfriend reach up and pop to line off... I installed the new vent hose mod yesterday and immediately went to fuel up. The tank was on fumes and the pump did not click off till I had 35. 9 gallons in. I was only able to top off with another 3/4 gallon. MUCH better than getting 25 gallons in , then dripping in the next 10 gallons over 15 mintues. I was in and out, completely full in under 5 minutes. Well worth the price of the kit.
