Re: Bigger fuel tank for a civic vx ?

Shoot, put a 5g tank on there, you would get better mpg but terrible range. You also have to think how this would impact your weight distribution. You could always add downforce to fix the weight issue, but this would negate the fuel savings lol.

Did it require any modification to make it fit the VX?

Does the fuel gauge still work accurately?


-The 13.5 gallon is a civic 92-95 jobber built by Spectrum Premium

-It not require any modification. It?s direct bolt-on

-Fuel Gage still work accurately.

I get now more than 1050km per tank (650 miles)

My only problem that I use EEfuel and it scrap my average fuel economy record. Thats why you see 43.14 mpg for my 90 day fuel economy. My last tank get me 52.48 mpg at 40f and get 651.3 miles with 12.41 gallons.

I can get easyly 700 mile on that tank because you can fill up 13.75 gallon when run out of gas

Sounds like a winner 650 to 700
mile range oh yea

Parts car

So I have access to a DX coupe parts car, any part for free just replace them with like from my VX. I am seriously considering swap gas tanks. I know 1.9 gallons is not much but still that is close to twenty percent farther between fills ups. Great for those road trips where it is hard to find the cheap gas. I am thinking about the future owner of the DX trying to figure out why they can only go 280 miles between fill ups.

Well I replied to this in 2007 since then I have more confusing info. If you look at my 3/2008 to 9/2008 fillups in my gas log I put a maximum of 14.4 gals in my tank and consistently over 12 gals in numerous times. Granted my car is a CX but it fits and does not leak out or clog up the Evap sys. The secret seems to be to fill the car up in a nose down to the right position proved by using a ramp under the driver's side rear wheel and find a pump where the ground also slants the same way.... Seeing is believing... Try it you might like it... You still have to keep clicking the handle many times to fit it in though. I only get 39 mpg's so I never made it to a 600 mile tank but I'm happy for high 500 mile tanks. The mileage does not get corrupted because of the over filling either.
