Fuel will bypass through that main jet whenever the engine is running. The bypass valve will have a light tension spring in it, about 2 lbs. There is a T fitting and a main bypass check valve and pill holder. The fuel flows from the pump, through the fuel shutoff and into the metering (barrel) valve. There are several variations of doing this. This is a modified version of returning fuel on an Enderle. any pointers would be great.:confused:įirst look at the basic plumbing for an Enderle below. I was told to use a by-pass similiar to a hi-speed by-pass instead of the main in the barrel valve. I've never worked with one but I understand how they work, just need a starting point. I've heard everything from don't do it, it won't work to 'no problem'. I'm about to run an enderle hat on gas and am looking for any tips also. Same deal.you'll just be tuning it different. Locking the mag at 34, working with the part throttle bypass and possibly some spool work you can get a pretty low idle.ĭrag guys also use this setup to keep from loading the motor on a hard burnout. At part throttle, you'll be bypassing some fuel back to the tank for cruising.which was selected by the spring and jet you put in the bypass.

Tune the part throttle opening by pressure and you can also do a pill to limit part throttle bypass.Īt full throttle, the part throttle (hole opening) will be closed and all fuel bypass will be throught the main jet. Then take your brass check valve out of the barrell valve and make that a part throttle bypass, using about a 12 lb (to start) spring. You can work with the Enderle and make them work better for part throttle by blanking off the main jet in the barell valve, then T in the to the main fuel line and put your main bypass there with a 2 to 3 lb spring. The most driveable injector for gas I have ever seen. If you don't have a hat already, that's the one to buy. Hilborn still makes this old hat and used ones still sell for near new price. for part throttle operation, the best setup is a Hilborn 4 port upright for gas.
