Are Non E85 vehicles equipped with fuel lines that can handle it or are they the different? I've seen boats that had fuel lines clog up from E10.

The fuel lines are probably ok, either coated steel, stainless, or multi-layer nylon.

Not great pics, but one is of the sensor mounted up with its lines going to it, and the other is of the line right in front of the fuel tank that i spliced in to. If you look closely you can see the second QD behind the first one.

Pace performance sells the kit to convert to flex fuel. I haven't called them yet to check and see if this is compatible with the 6.2. Anyway here is the link.

I am particularly interested in the fittings with the quick connects to this sensor. They look like 3/8" or 1/2 male JIC to quick connect that would plug right up to the sensor. If I had those I could just buy some like sized female JIC to a ferrul lock fitting that I could just connect to the cut steal fuel lines and I would have this mod complete.

 

I'll call these guys and see if I can just get those fittings... Thanks.

You'll be good to go. I did this mod as well, still working on the tuning aspect of it with BBP but plumbing the sensor in and hooking it up is a piece of cake! As far as the rest of the fuel system thing.....it's all identical between FFV or non FFV so no worries there!

I am under the impression the flex trucks have larger injectors due to the need for more flow when using ethanol. I could be wrong .

I'm almost positive another member in here went to the parts counter and both he and the guy behind the counter started comparing part numbers between FFV and non FFV truck and all pumps, injectors, etc were the same part numbers.

When you think about it, this makes complete sense. The difference in E85 vs non E85 trucks is $100.00. I assume that is to cover the cost of the sensor. The "upgraded" lines, injectors, ect. end up in all trucks because it is cheaper to just have one set of parts for all trucks.

It depends on how many non- FFV trucks would have the FFV rated components.

 

If the fuel pump alone costs $4 more for FFV internals - x 250,000 trucks, thats a million dollar cost save just hanging out there.

 

There is no way its cheaper...

Maybe there is more to it than cost per part. Maybe some efficiencies are gained by having 1 set of parts across the entire line that make up the difference. Either way, if they could cut costs by putting "lesser" parts on non FFV trucks, they probably would, wouldn't they? It seems like parts made with FFV in mind are more robust than non FFV parts. Maybe GM is just putting the higher capability parts in all because these are 40-50K + trucks and we customers deserve more robust parts in these trucks. Perhaps that is why GM consistently has the most reliable, longest lasting trucks on the road?

No, the efficiency created by reduced part numbers would be greatly offset by the component costs. Its unnecessary expense and a waste of money from a business standpoint.

 

I have a lot of experience with automotive fuel systems and components and i can't think of any reason to use FFV rated materials in a system if the intention was only to certify it for E10.

No offense, but you seem very dead set on the systems between FFV and Non FFV being different. Can you find some facts around this, other than thinking they just wouldn't do it?

Right, I think it was stated earlier in this thread that the part numbers for are identical for both systems. So at this point, unless proven otherwise, the reality is that they are all the same. There is only value in discussing "why" GM would do this and if it meant higher cost, I would bet they wouldn't. Therefore, the cost must be a wash.

      Transmission Woes :-(

      By No1UKnow · Posted

      Hello All!   My 2019 Colorado 3.6 LT, 4WD Crew Cab has approximately 77,500 miles and I recently began experiencing the well-known transmission shudder between about 30 and 65 mph. The problem had worsened to the point that I could no longer attribute it to road conditions - and I had decided to bring the truck to the dealer - when recently, I experienced a sudden loss of power while driving at maybe 40 MPH. Several warning lights flashed, the “Check Stabilitrack” message appeared, and the Check Engine, Stabilitrack, and Traction Control icons remained illuminated. The truck regained driving power, but it stayed in a low gear with unusually high RPMs for the speed. (limp mode?) Because I was only about two miles from home, driving slowly, I was able to make it back and run an OBD-II scan, which showed fault codes U0101, P0700, and U0100. My next trip in the truck was to drive it to the dealer the following day. That trip began normally, but after about a mile I experienced another loss of power, along with the same warning lights and the same “Check Stabilitrack” message. As before the truck remained driveable, but again operated at an abnormally high RPM-to-speed ratio and seemed stuck in a single gear. About a mile later, the dashboard lit up once more, this time displaying “Check 4WD.” Soon after that, I arrived at the dealer. I have verified that the truck still has its original factory transmission fluid, which means it has never received the corrective fluid exchange outlined in GM Technical Service Bulletin #18-NA-355.  That was Thursday of last week and I've heard nothing yet from the dealer.    According to Technical Service Bulletin #18-NA-355 and the build date of my truck, my truck should have the newer LV fluid. I've done a little research and read something about a problem with the wiring harness as well.   Anyone have an insights into this situation?  Thank you!!

      Gas Prices

      By PhilB · Posted

      Did you even read this article?   Even the title of the article says "U.S.-Iran Deal Doesn’t Mean a Swift Return of Oil and Gas Flows"   Remember, crude oil prices are based on FUTURE purchases by the oil companies.  Gas prices are based on FUTURE purchases by the station.  This article stated that many of the oil producing nations have to restart their processes to get the oil produced.  Then the oil has to be shipped to wherever.  And it doesn't get there overnight.  And most of that oil is not coming here. Check out this site:  https://afdc.energy.gov/data/10621   A graph will pop up to show where the US imports their oil from.  Notice that there isn't a lot of import from OPEC and Iraq.  Most of the US import comes from Canada. The US oil produces are selling their oil on the open market, which is why the US fuel costs went up.  So you're correct, the US oil companies are going to slow walk the price downward.
