Interesting comment. I tried searching this forum before posting initially but found very little on the subject which is why I posted in the first place. I’m curious why you state it was “dismissed as not feasible”. Seems totally feasible to me if a aftermarket company offers a larger fuel tank for the same truck which is diesel powered and whose numbers are a fraction of the gas powered counterparts…. What am I missing Bikerjon? Who wouldn’t want the ability to go 600+ miles between fuel stops as opposed 380 or so?

So did you ever put a bigger tank in your truck?

I filled the tank today. I was running errands when I got the "Low Fuel" warning. I stopped and fueled it up to the brim. Some quick math:

  • Remaining Range Indicated = 50 (multiply by 2 to get a real ballpark of range with the 50-gallon tank)
  • Recent Avg MPG = 16.8
  • Calculated fuel in tank = 50(2)/16.8 = 5.95 gallons
  • Tank took 43.5 gallons per the pump
  • 5.95+ 43.5 = 49.45 gallons total 
  • ~.5 gallon is not accounted for in the range calculation.

I'm surprised that there is only .5 gallon not accounted for in the calculations - the gauge is extremely accurate.

 

Photo from pump; I went to one of the cheaper places in town at $3.01/gallon

That's not 93 octane is it?  93 octane in west Florida is about $1 more.

Different states have widely varied retail prices for gas. Cost of supply, transport, and state tax are some of the variables. The post isn't about the price of gas - it's about the freedom of range the larger tank has.

Latest fill was with 725 miles on the tank at 15.8 mpg indicated. Took 45.4 gallons (US) and range indicated at 40 miles (~80 actual). 

Zero issues.

Has anyone looked into to taking the Titan 43 gallon tank and using it for a gas-powered truck. Is this possible and how much modification would be needed?

Fuel stops are part of owning a vehicle, what's the problem?

Open highway Pepper gets about 25 mpg so one fuel stop between De Kalb Illinois and Denver. A forty gallon tank gets me there on zero. LOL. I stop for the day in Lincoln and stop several times a day. Often at a station. So...... My butt gives out before the tank does.

I’m always measuring time on trips. My odyssey will make the destinations these days without filling up. My trips are 6-7 hours mostly interstate driving. Rest stops are way quicker at rest areas than any gas stops. Saving me about an half an hour total. It makes a difference.

When towing a tall trailer on the interstate, I get 8-10mpg; for a stock range of ~184 miles max. I find this unacceptable, especially driving across the great plains at night. Looking for gas every 130 miles isn't a good feeling (or probably less, where is the next town with an all-night station that isn't 20 miles off the highway?) .

 

I don't put many miles on my truck; but when I do, it is often the above scenario. Having double the range makes my travel less stressful: I buy gas when I need a break, not every gas station.

 

It's not for everyone; but I love my 50 gallon tank!

I had a 100 gallon tank. I tapped into the return with an old fashioned manual switch by the driver seat. It was awhile ago I don’t know if you could do it on new trucks. I also had a fuel pump on the tank.

I'm sure it can be done. I need the space in the bed for other things.

I had an L tank with a tool box on top. Even an air compressor behind it. They were in front of my gooseneck ball. All that was in front of my fender well. Plenty of additional room in the bed.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Thanks - I wasn't quite caffeinated this morning. 2:1 makes sense, turning the crankshaft 360 degrees will turn the cam 180 degrees, and had I done that, the cam's dot would be at 6 and the crank's at 12 again.   I went ahead and took the sprocket off anyway, aligned everything dot-to-dot including the balance shaft just for s&g. I'm glad I did because I discovered no Loctite on the timing sprocket bolts. Maybe it's not required, but at only 20 ft-lb torque spec, those bolts aren't in there very tight. Cleaned and reassembled with some thread locker and torqued.   A general observation: Less is more with RTV. If a little doesn't stop a leak, a LOT probably won't, either. RTV is thinly veiled revenge, in a tube...

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.
