Just think of all the money I'm saving you, yet you tried to rob me on your shipping quote?
The hose I pointed to, is made of rubber, with a nylon web cover, pinch it with the proper plastic pliers as I posted above, and NO DAMAGE! To rule out the FPM as the source!
Fuel economy on the H3 can be adjusted by REDUCING THE WEIGHT. BTW, I did not purchase my Hummer for fuel economy!
I just made a video for you, cold start, last started around 10am yesterday:

 

You are saving me money, for sure! I think the shipping quote was so high because the guy wanted to ship them 2 to a box and the boxes were like $35 or something ridiculous. I'll save some cardboard and make a box for a single rim and get another quote on it (per rim) haha.

I am honestly concerned the line will crack with how rigid it is. It feels fragile to me. I was going to use vice grips with hose on the jaws but my intuition tells me I'll have a bigggg headache trying to replace the fuel line if it cracks.



I have also reduced the weight (and added weight with the bigger rims and tires) by removing the spare & carrier as well as the rear seats. I am almost ready to swap the mechanical fan for my e-fan setup. I'll save a little mpg there, too.



Thanks for the video! I dig the thumbnail.

 

No more grape juice or ketchup stains in the coolant reservoir.

I made a major mistake/discovery before constructing this apparatus: clumping cat litter is like concrete (I had the idea of sloshing pebbles around the inside to scrape the inside clean and then though, "I bet cat litter would do the trick." It did not do the trick. It turned to concrete on the inside and I spent an hour blasting it out of there.) Do not use clumping cat litter on the inside of anything!

That hose should not be rigid? I can pinch my hose with my thumb & index, not enough to make it stall but it does collapse. You only need a 1 minute squeeze on it to verify leak down.
Nylon braided fuel hose:

 

The fuel line must have still had pressure in it when I pinched it by hand, which is what led me to believing it felt rigid... I went out again to feel it with my hands (has been sitting for 24+ hours) and it was soft. I will check for the leak down and update you. Thank you for your persistence

 

Connect gauge,koeo x2 pressure to max, clamp hose and observe for 1 minute, clamp off.

 

Now I'm sketched out again! I did the above and the spot on the fuel hose I clamped feels super soft and pliable now (much more so than surrounding area). I'm concerned I've compromised the strength of the hose in the clamped spot. I imagine it is soft from my vice grip "massage." I'm sure it will tense back up after some unadulterated gasoline pours through its veins.

However, it does confirm my leaking injectors. The PSI dropped from 57 to 52 in about 15 seconds. After this procedure, I knew with confidence the engine would not start on its first "timed" attempt, so I turned the key to confirm, and indeed the engine did not start.

Current hypothesis: injector(s) leaks under pressure leading to too much fuel in the combustion chamber to ignite quickly during the cranking procedure. After a few cycles of cranking, excess fuel is expelled into the exhaust (often resulting in back fires upon start-up). Once excess fuel is out of the combustion chambers, the air fuel ratio is high enough to allow for proper combustion, allowing the engine to start. Sporadic rev'ing of the engine resulting from excess fuel pushing past the leaking injector(s), providing more fuel.

I imagine the amount of fuel/air delivered during the "timed" portion is different than the "manual" cranking of the engine with the key held to start. Maybe this is what leads to the engine starting immediately on the second attempt, or maybe the "timed" portion is just long enough to perfectly expel the right amount of fuel from the combustion chamber.

 

Stop being a pansy, If the hose ever gets damaged enough to burst, chop the crimp clamps and replace the hose+install high pressure clamps, new fresh 500psi rated hose(burst pressure 2,000 psi). Better to happen in your driveway than on the road. Your hose is fine(check fuel pressure), since it's not leaking fuel, and protected with nylon braid. I've clamped hundreds of fuel lines over the years for testing and never had an issue.

 

Haha thanks for the encouragement I checked the fuel line again this morning and it firmed back up. Did you see my post on the other shipping rates for the rims? Give me an offer on them I'm trying to clean the garage haha.

I picked up a nice little 2-in-1 laptop with detachable keyboard to use with HPtuners and such. I'll add an update photo when I figure out how I am going to mount it.

 

Did you get a tight clamp on the hose?

Without clamp: "mine drops 5PSI in 8 seconds"
With Clamp: "The PSI dropped from 57 to 52 in about 15 seconds".
Clamp it like you own it, just don't cut it!
Not in a hurry on the wheels, been busy listing/selling/reducing my tool collection, we are moving soon. Anything I can sell, I don't have to move.
