Re: Dual tank fill-up to top

Had a sort-of-kinda-like problem on my recently sold dump truck. First thing to look for is whether the fuel fill spot ("fuel cap") is higher than the tank(s). Second, if the "fuel cap" is indeed higher than the tank(s), does the fill pipe run between the cap and the tank in such a way as to allow fuel to gravity flow down or is there either an extended run of level fill pipe or does the fill pipe even run "uphill" from the fuel cap before dropping down into the tank. On my truck, it was the latter situation: there was a slight, very slight, uphill run between the cap and the first bracket on the hose. For whatever reason, it would fill fine until the tank was 3/4 full, then I couldn't get any more fuel in the tank...it would just come back out. I lengthened the bracket, had a local shop shorten and straighten the fill pipe (so it ran entirely downhill between the cap and tank) and the problem was resolved. Another option of course is to put the fuel cap at a higher location on the bed, but that's probably difficult with the aftermarket bed. Interesting. Well, I took photos and I found two things. Only the back tank has a 3rd hose that is capped (is that the vent hose)? Otherwise, yeah, there seems to be a slight drop but I cannot tell if it is sufficient or not. I am posting links to the photos.

Hello all. I am 7,000 miles into owning a brand new '21 Chevy crew cab, cab chassis 4x4 DRW gas truck that came with dual fuel tanks (40 + 23.5 gal). In the whole ownership of the truck, I have successfully filled it up full maybe 1/3 of the time. It is my understanding that you are not supposed to use the front tank for fill-ups, correct? I tried a few times and it spat fuel back immediately so I concluded that the back tank is to be used. The way I understand it is that fuel flows from back tank to front tank, yes? When I use the back tank, I have to open the front tank first to "depressurize" (get air out of) the whole system - this I found out on my own - without that the back tank spits fuel out as well. Is this correct? After I do this, I am able to fuel up but often I can only get to between 3/4 and full on the gauge. After that, it spits fuel back from the back tank as well. What gives? Is my fuel system faulty or is this normal? Are they this finicky? Thanks!2.5KViews0likes14CommentsRe: Chevrolet 6.6 burning oil

The answer is always no. Or at least no one has offered enough yet! Think I’ll hang on to her a while as posts like this are all to common on different forums. As far as the 7.3 Ford gassers. We run a number of them in our ambulance fleet. 11 ambulances with a distributed call volume of 23,000 plus a year. Also have 4 F250 Battalion Chief trucks with them. One truck is at Ford now for engine replacement due to a lifter issue at 12k some odd miles, 2 ambulance have had engine replacements (one lifter, the other I believe valve issue going down into the engine) and numerous other issues like plug wires, coolant leaks, and oil consumption. Now admittedly, the ambulances get run hard. But all were low mileage issues, like well under 50k miles. I know the engine really hasn’t been out that long. But so far, they have been nothing like the pre 2020’s that had the 6.8. At least for us. Those engines took a beating and kept on rolling! YMMV. Interesting to hear about your department's experience with the 7.3 gas. We don't have any yet, have 5 ambulances with the Ford V10. Just like your department, the guys beat them like rented mules and we have no problems that I've heard of. Most departments in our area are going with the diesel Ram 4500 for ambulance chassis, despite the extra length and cost. Our logistics and acquisition folks have explored this option as well. However, our shop guys have basically wrote off diesel engines and fight them tooth and nail in our EMS units due to all the idling time and emissions issues. We have ordered solely gas since roughly 2016 in ALL Med units. And yes, the 6.8 was solid as a rock. I feel like the 7.3 may get there, it just isn’t there yet. There is now a 6.8L gasser being offered in the XL trim on the HD trucks if I am not mistaken.4.3KViews0likes0CommentsRe: Chevrolet 6.6 burning oil

The 6.6s have been out since 2020 - there are plenty of trucks now that are higher mileage. The consensus is that there were issues with brakes (loud like trains) and a few electronics issues like dead radios etc. Oil consumption has been talked about in all the groups every now and then but the consensus is that the majority of the trucks do not consume oil and the ones that do - do it within the GM guidelines/expectations (there is a 2020 bulletin about it). I think GM did the right thing to pair the new engine with the tested 6-sp tranny and that way work out all the bugs / limit the variables that could go wrong. Now GM is going to the 10-sp tranny and some people are ecstatic, some are not. Overall, the 6.6s have shown to be good and strong engines and IMHO the most reliable/least problems from all the 3 HD gas engines. Not the most powerful but most reliable. p.s. this is from the GM TSB: "Oil consumption of 0.946L/379L of fuel (1 qt./100 gal.) or less is considered acceptable." https://static.nhtsa.gov/odi/tsbs/2022/MC-10211061-0001.pdf4.3KViews0likes0CommentsRe: Valve stem extenders for inner wheels (DRW)

Not that expensive and it keeps you from being at the mercy of whatever air compressors you can find. A hundred dollars or so for your own compressor is chump change considering what you have. I do carry it but I don't think it will accept different chucks. I agree with you - will just buy a proper portable compressor that does. Thanks! :) You probably don't need to buy another compressor. The chuck most likely just screws on and you can buy an adapter from any decent hardware store that will allow you to change chucks easily for less than $20. Thanks. I will try that first.630Views0likes0Comments
