View Full Version : Fuel Acquisition

08-12-2002, 02:08 PM
I have an 83 ITA rx7 that hasn't been raced since last year and I'm getting it ready for it's annual tech for this year. (I just picked it up). I was told I need to add a fuel acquisition line somewhere under the hood. I've got an idea of what this is, I was wondering what you folks have done for this. I have a rubber fuel line running to the carb that I could easily tap off of. I was also told that having a rubber fuel line there isn't that great of an idea either.

Thanks for any help!

Most people do not use the return line on the carb. So what you do is take the fuel fitting out of the center where it Ts off and goes to the fuel bowls,go to your local Ford dealer with the fitting. Ford makes a fuel rail valve(looks like a valve stem on a tire on one end and is threaded on the other end) that screws right in to the end of that stock fitting. All you need to do after that is weld the small hole that was used as the return, screw in the valve with a little sealer and you are good to go. I put a steel valve stem cap on mine that has a urethane seal in it for added protection. Then all you will need to do is make up a small test hose(I used a lead off an old basketball pump) and keep it in the car. Final cost is about $2.75 and most of all it is safe.

The approach I used (the tech guys loved it by the way) was to not go with the "T" approach but to put an aeroquip "Quick Connect" fitting in the main fuel line. Female end on the tank/pump side and a mail end on the carb side (yes, I use steel braided fuel line). Then I put an extra male quick disconnect end on a length of extra rubber hose. To get a fuel sample, you disconnect the fitting and plug in the extra hose, turn on the fuel pump and you have fuel. I keep the extra hose lashed down in the engine compartment or you could have your crew carry it.
The quick connect fittings are the type rated for aviation hydraulics and yes they are specifically approved for carrying fuel (even aviation fuel). I think its a safer long term approach than the T-needle-valve set-up...I'm afraid gasoline will cause the seal to leak in needle valve over time.
I got the idea from a guy who races in Grand Am cup. He showed me a brochure where somebody was selling the solution for I think $70, but i purchased the components at a local Aeroquip dealer for less than $30.

I was concerned that the valve might restrict fuel flow or capacity. I saw no issue in the last race (up until the point I cooked the engine...but thats another thread http://Forums.ImprovedTouring.com/it/wink.gif)

Thanks for the help guys. Due to the speed that I needed this thing we actually went to homedepot and pieced a nice little deal together. Hope it works!
