The engine that I've been slaving away on all winter is in it's very final stages and should be installed within the next couple weeks.

My question is: Have any of you ever welded a drain plug onto your gas tank so you can drain it's contents when needed? I'm simply looking to do something that will allow me to change out C16 to 93 Oct. (and visa-versa) when needed.

I have searched with no luck and excuse my ignorance if this is a feature that is currently built into all gas tanks. The car (gas tank) in question is a 1997 Acura Integra Type-R.

All feedback and better suggestions are welcome.

 

in my 93 civic, it already has a drain plug....

 

yeah civic's and integra have them. i know integra have them on the driver back side of the tank. 17mm wrench will take the nut loose

 

You can always just remove the hose from the fuel regulator and use the fuel pump to pump all the fuel into a container through that.
