Hey guys... 2014 GMC Sierra SLT 1500 125K miles. I noticed a gas smell from the truck a few days ago. Crawled under and saw some drops of gas dripping from the bottom protective shield under the tank. Hooked a boroscope camera up to my phone, and on the top of the tank, found the leak. Seems to be dripping from where the high pressure line hooks up to the fuel assembly fitting (see pics). I've never needed to drop a tank, or replace any of these parts, so this will be round one.

 

My first question is, which is the easier/preferred access for those who have done it... dropping the tank, OR, lifting the bed off? I can have 3 guys come over and left or tilt the bed, so just wondering from those with experience, which way do you find easier? I don't have a lift, so if I'm dropping the tank, it would be all ground work in confined space, so I'm leaning with tilting the bed.

 

Next question, WHILE IM THERE, how deep would you go replacing parts? Everything fuel related is all original. I'll definitely need the assembly im guessing by how it looks, and the high pressure line, but I'm not sure how they attach? Is this a snap fitting? If so, is it a separate purchase or typically comes with the line or assembly? Would you also replace the charcoal canister if you were doing it? Thanks for the time... Chris

      Gas Prices

      Can ask that about a lot of places.   Holiday sells 91 for $1 over 87 octane. BP 93 is 80 cents. Amoco 93 is 80 cents Kwik Trips is $1.20 for 92 or whatever they have and $1 for the 91.   I know that this is not exactly same as what you are saying with the premium to premium debate of those two stations but why is there such a difference. Top Tier this and that, it's all BS. All the fuel comes from the same damn refinery, so give me a break.

      Why does Mobil Premium cost 90 cents a gallon more than Shell Premium when their regular offerings are but pennies apart?

      Was all the way down to $3.69 a gallon but then jumped back to $3.99 just because for some reason.   Diesel floats between $4.80's to $5.10ish a gallon. I even saw Diesel #1 for $6.09 today but nobody in there right mind even buys that in the summer.

      OTA updates and radio still cuts out

      Mine just keeps lagging or getting stuck on the reverse camera. When I turn off the truck, get out, and close the door it will still stay on. It’s very intermittent and I would not be able to duplicate the issue.

      I was checking out fuel prices at my farm fuel retailer at their pumps and yes the farm price is a bit lower than the non dyed fuel and was glad to see that the regular farm gas price has dropped a lot from what it had been but what blew me away was the price of diesel as the spread now compared to before the prices went up earlier in the year, diesel was actually slightly lower than gas which was a switch from the theme the last number of years. However that sure isn't the theme lately and definitely not right now. The prices I will post are not from that retailer but just looking at gasbuddy for the main city in this area and instead of posting the lowest price someone found I will list the higher price ( and that may not be the highest price, just whatever someone posted on gasbuddy ).   So regular gas and there are a lot of stations listing the same price for regular is 1.68 a liter, premium 2.00 a liter. Diesel 2.03 a liter for a top price I saw on diesel.   Figures out to 6.36 a us gallon Canadian funds for regular and 7.68 for diesel. With the US exchange rate it would be 4.58 us for regular and 5.53 for diesel.    Thought I would figure that out to get a picture of what it settles out like compared to various US prices and its about the same as the current price in Fairbanks AK as Anchorage tends to be lower. So yes, these would be the prices and higher along the way on the Alaska highway where they know they have a captured market !, for fuel prices for those beginning the long drive back to the lower 48   The problem is our Canadian dollar and going to the states that have the high prices, boy do we pay then !
