Holy crap! Been some action in the driveway!

I got pushed to the third page in just 4 days... Good work boys!


As it were, @bent72 has a point on his "run better gas" business...

I have a bone stock, smog era 350, and have been running base model gas. I filled up with mid-grade, and wowsers, never going back...
 
91 octane premium here is ethanol free at a lot if stations so I run that in my stuff that matters(lawn mower and dirt toys). Of course my wife's Denali has to have it and 2 are diesel.
 
I'm going to play around with the higher octane and boosting my timing a little with it.
 
Went to get emissions done after work today.

The guy that I take my truck to is so cool.

He doesn't care what is what, as long as it passes.

No EGR? No problem, ss long as it passes...

Doesn't pass the first time? No problem, we'll tweek it.

He was thoroughly impressed though. When he said it was just a touch too rich at idle, and I pulled out the FiTech handheld and leaned it out in 5 seconds, he laughed and said "that's cool!" Retested it and passed no problem.

Nothing spectacular to report.

I went through and retorqued the front wheel bearings one more time. When I checked it the last time (2 weeks ago) I was in a rush, wanted to make sure they were good. Put my junkyard hub on, checked my u bolts, greased all the zirks, thought about installing my Christmas present from last year, didn't get too far with that. Who needs a stereo anyway?
 
So if anyone hasn't seen the august 20th trail ride in the rocky mountain regional section, I am having a fuel issue that seems to be heat related. 2 or 3 times while doing the trail, the truck would sputter out and die. During these times, I had zero pressure in the fuel system. Before anyone chimes in with "were you outta gas?", both tanks had atleast 3/4 in them, and I know that both senders work. Switching between tanks wouldn't help, and physically touching the inline fuel pump told me that it was only around 95-100 degrees. (I have a very young daughter, and the pump was no hotter than her bath water... yes, I have a temperature calibration in my hand... lol)


The pump was also trying to push fuel, I could hear it runnimg the whole time.

The only thing I can think of is a vaporlock/fuel boiling situation, as the truck would fire after 15-20 minutes of sitting. The pump would change it's tone as soon as it actually made the 58 psi required, and then the truck would fire right off.

This only happened at crawling pace, and never at speed. I drove the truck more than 70 miles back to the house, completely hiccup free, ran like a champ.
