OT: CNG bi-fuel conversion kits

I'm thinking of installing a Compressed Natural Gas kit in my 2000 f-250 5.4L. With the price of CNG at less than half the price of gasoline per mile, and a CNG station opening up along my commute, I'm seriously considering it.

A single-point injection kit is around $700, but a sequential multi-point kit is around $1500. Apparently, the sequential system gives better power and efficiency, but both work. I'm not sure the better system justifies doubling the cost, especially when I could just switch back to gasoline when I need pulling power.

A new DOT-approved 11.4 gallon (gasoline gallon equivalent) tank is about $2000 and the DOT-approved mounting straps are another $250.

Seems like a lot of money, but it also seems like it would pay for itself in about two years if fuel prices stay like this. And even then the tank and some parts would still hold much of their resale value as long as I don't explode!

Has anyone ever done one of these conversions?
 
Oooh, bad idea posting that here... You're going to get labeled a abundant pinko commie greenie granola hippie.

Come back when you find an attachment that DOUBLES your gasoline consumption...
 
Do you have a convenient fast fill station nearby?
If you have NG at the house you can also install a fill station at your home. This takes a little longer since you are stepping up the CNG to around 3000-3600psi depending on the station.

I would not do the conversion without a DOT tank, for your safety and others within a 1/2 mile of you.

Very possible you will see 1-2mpg improvement. You should be around $1.60gge for CNG while gasoline is at $4.00/gal right now.

Go with the multipoint injection. You will not loose too much HP and can tow just fine. Around 10% or so HP reduction.

If you want to discuss further drop me a line.

And when you are done, The State and Federal Gumment will tax the he!! out of it like they do gasoline. Poof. Savings gone.

I would check out the filling station about road use taxes. The Gumment may go back several years to collect.

Buyer beware.
 
At some point in the not-very-distant future CNG, or methanol derived from CNG, is going to achieve equal status with---and probably surpass---gasoline as our primary transportation fuel. There will be some hitches and glitches, but there are just too many compelling reasons this is going to happen. My next truck will come from the factory CNG-equipped.
 
And we have a Bingo, from John730d.

Guvment's primary purpose going forward will be to fund all its giveaways- they can't stop the gravy train, or there will be rioting in the streets, and both parties know that. nnalert will preach balanced budget, but when it comes right down to it, they will go along with the giveaways, too, if nnalert concede some pie-in-the-sky repayment for it in the future, which will be conveniently forgotten before it comes due.

They also want to encourage "green" technology. I think they will tax natural gas to where it is only slightly more attractive than gasoline or diesel, to lure the unwary into doing it. It's "greener", don't cha know. But good luck on getting enough advantage to actually pay for the technology.

They're all a bunch of scoundrels- the only solution is a universal term limit of 4 years, on both houses of Congress and the Presidency. NO LAME DUCKS- that's when they do the most damage. If Brocko gets re-elected, it'll be "granny bar the door".

Read quick, the poof monster is breathing fire. . .
 
In Missouri you buy a sticker for the windshield(in
the 80s it was $60.00)that is to pay for your road
use tax. Just know the states are going to collect
their taxes, but it is still dirt cheap fuel.
 
You"ll probably have around $5,000 in a home filling station, you can google Phill or Impco Technologies if you want to read more on them.

A home station is not a "fast fill" unless you have a storage tank too, think you would have around 10k in that system, not sure you could get one for a home. If you tried to do a fast fill, you would probably suck out all the pilot lights within a mile of your house, assuming you could suck the gas that fast and compress it.
