8 GGE tank to replace 6GGE tank?

[ajgiorgi]

I was wondering if you could somehow get a Honda factory 8GGE gen 2 or 3 tank and replace the 6GGE tank on a gen 1? Anybody tried this? Might be worth it if you can keep the trunk and the spare.

As far as I understand all GX's have a 8GGE tank. My first CNG car was a 99 GX and the factory GX service manual supplement said it was 8GGE also. The largest fill I got was 6.7 GGE after about 220 miles. The newer GX's have better gas mileage that is what gives them a longer range.

I never got that much gas into my tank, usually 5.2 with the light on. Ok, so if it's an 8GGE, what's the biggest tank you think I could get in there without having to take out the back seat?

I'm certain my '98 has a 6GGE tank in it, I've ran it down to 350psi before fillup and it took about 5.8GGE, the one time I ran it out of fuel it took almost 6GGE on the dot.

2013 I need a new tank, it'd be nice if the bigger tank fit.

I wonder if the fittings are the same on both tanks? It be cool if you could run the gas out and take the 6 GGE tank out and replace it with the 8GGE with no modifications. Maybe a crown vic tank? I think those are 8 GGE also.

It would be nice if we had some stations which could really do 3000 psi (like we used to) and even better if we had some which did the 3600 psi that the car is capable of.
I was only able to push 6 gge into my 99, even with pumps doing 3600 psi.

My wife drives an 05. I'm lucky enough to have to refuel it for her. Hell, it keeps her working. I have fueled it many, many times with barely a whisp of fuel left in it. I have NEVER put more than 7GGE in the tank at either Placentia or Whittier 3500 pumps. My understanding is a fast fill pump will not fill the tank. You need a slow fill pump to get 8GGE.

I think the reserve in the tank is pretty large once the fuel light turns on. I recently got over 7gge in a Civic after driving it for a while with the fuel light on. You can also install an extra tank next to the main tank. We have a 98 right now with an extra tank that gives the car an easy 300 mile range. You can see a picture of the trunk here: http://www.cngutah.com/forsale/85/main.html

For the record, since 1998, all GX's have had an 8 gge tank. Once the bingo light comes on, there should be approx 1 gge left in the tank. I've never gotten more than 6.7 gge in my '04. Heat expansion from a fast fill will usually cost you about 1 gge-1.5 gge. Temperature and the pressure the compressor is set at will always be a factor.
