Towing issues yesterday...?

Set off for Tucson yesterday with the funny car and got just over the Grapevine and stopped at the rest stop to grab a quick bite.

After 20 minutes or so, my 2007.5 Duramax would crank but not fire. it was 96 degrees out side and we were able to prime the pump and fire the motor but were concerned about it re-starting after shutting it off so rather than continue on to Palm Springs and then AZ where it would have been even hotter, we decided to play it safe, considered ourselves lucky we avoided a $1700 towing bill for both truck & trailer (after being on the phone with AAA for over an hour) and just returned home, canceling our entire weekend.

Of course after running non stop for almost 6 hours and returning to weather that was 20 degrees cooler, it started several times perfectly without issue.

My mechanic says the cartridge will develop seal leaks and that I should change that unit which comes with a new filter as well.

He also mentioned lift pumps as an option and wondered what everyone's thoughts on those were.

I cannot have this happen again while towing long distance and obviously the only way to know if these solutions correct the problem would be to tow again in hot weather...not really a comfortable choice.

Any suggestions guys...?

What cartridge is he talking about? Sounds like the fuel got too hot somehow. How does the fuel cooler look (small radiator in front of the fuel tank area)?

Lift pumps could be the way to go...

 

Went with the Kennedy twin pump deluxe kit since my mechanic had a similar year truck and installed that set-up his and it's easier to work with a product you're familiar with.

 

I also spoke with John Kennedy personally and may go with his custom tune as well, he sounds like a pretty sharp guy.

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
