#1 of 6 Extra Fuel Tank by gashog53 Mar 19, 2008 (7:11 pm)
I have a Honda GX 2003 with a extra 4 gal tank. I should have about 12 gal capacity. i know that you can't get a full 12 gal at fill up, but I think I should get at least 10 gal. The most I can fill to is 6.7 gal and thats with the gauge below the red bar. Do I have more fuel then is indicated by gauge. Replies to this message: lakewood90712 (Mar 19, 2008 9:28 pm)

Replying to: gashog53 (Mar 19, 2008 7:11 pm) 6.7 gge is a typical fill up from almost empty 3600-4000 at 70 deg. f.,with the single factory tank (low fuel lite on and driven about 40 miles more.   The most I ever got was 7.2 gge on a fast fill. Bone dry empty, towed into the station.   Sounds like you have a closed manual valve or stuck check valve in the system.   Did you buy the vehicle used with the extra tank ?, or have it installed by a shop. Prob. time to have the shop who installed it have a look at the problem.
#3 of 6 Interested in adding extra fuel tank to 2008 Civc GX by adrianr Mar 26, 2008 (1:55 pm)
Hi, I'm interested in prices paid and contact information for places that you are familiar with for adding an extra tank(s) to Civic GX's. Also curious, does anyoone know if it affects the factory warranty in any way? I have a few quotes, but they are all above $2500....more than I want to spend.

Replying to: adrianr (Mar 26, 2008 1:55 pm) Sign up as a member on cngchat.com . It's free , just like this forum is.   Then send a pm to a member called adea. I think his name is Gary.   He had an extra tank installed in AZ. for far less. I personally would not recommend doing it , but adea and many others have , and report no problems.    As to warranty , ask your dealer.
