Gas Cap Question...

[Airman84]

I posted this in the GENERAL forum by accident so I am posting my question in the TECHNICAL forum. I am designing a military gas cap to fit on to the H3/H3T. I was wondering if there is anyway around the "check engine light" that comes on if the cap is off. Is the light only coming on because it needs a constant seal or is there something in the factory cap that prevents the light from coming on when it is properly attached? The dealer, ofcourse, is telling me that there is no-way around the light. I should be able to get a good seal, the caps I'm using were taken off... literally taken off... of military aircraft that have been used/flown for over 30+ years! FYI... I have them because they were removed from the aircraft for an upgraded model... no theft! lol. I will have pictures soon and once I get the design working without problems I will be more than happy to make acouple extras to those who would like one. Thanks!

I would say it would work if it was sealed.
Post some pics ,Ill take one as long as its not chromed

Try it out. Even if you throw a alarm code. It will clear itself after a while. You may be better off leaving the stock cap and making a mil type cover with a lock...

First off... NO CHROME! lol. I'm in the process of getting rid of the chrome package I had to get on my H3T. The system is straight off the airplanes... origional paint is red and unpainted aluminum.
I'm bascially worried that after I modify the area around the gas cap to accept the airplane recepticle that it might not create a great seal and the light will stay on until i put on the origional cap.
I do not want to just make a cover, when I make parts theyre all functional... not just for looks.

I am interested in what you come up with.
I hate the gas cap and I do not want a locking door either. Those doors are nothing but problems. Especially when its 20 below, 50 mph wind, blizzard, and you drop the key in the snow.

Just installed the cap on the truck, havent had the check engine light come up yet, fingers crossed! I'm going to take the cap and recepticale off and have the recepticale powdercoated flat black to match the black plastic around the filler neck. I have acouple pictures, i'll try and post them after work, came out great!
