1. Cap off the front petcock outlets, left and right.
2. Run fuel line from left petcock to lower right T.
3. Run fuel line from right petcock to lower left T.
4. Upper T's are vents, run either to air box nipples or leave open.
5. Make sure all 4 front carb boots have vacuum caps on the nipples.

If you wish to run inline filters, splice them in the fuel lines.

as a percaution, one might want to hold a small container under the petcocks with no hoses on them to make sure that they hadn't been taken off and put on the wrong side. just turn the petcock to "on" and cap the other one. if you cap the "on" accidentally instead, you will have no reserve.

Mr. Johnson has a good point. Verify which outlet is ON or PRIME. PRIME does leave no reserve when it runs out. Reserve is very good for the legs and the back!!!

Here is an alternate routing I have used on bothe of my 81 specials and had no issues at all (warning, this was drawn freehand in paint, not by an artist.)



The sketch assumes ON is rear which is how it should be if the petcocks were installed correctly. OBviously, the purple VENT lines only apply to the 79 Special or bikes where the older style carbs have been installed as replacements. HTH

thanks everyone for the help! made it nice and simple. now i have to wait another hour for the battery to finish charging and ill try to fire her up for the first time with gas! iv got her going for about 4 seconds before with starter fluid

Yeah do what bikerphil said.Just remember to turn the petcocks off when parked.Otherwise if you have a stuck float valve she might leak all over or fill the crankcase/trany full of gas.Semper Fi Terry

The image above shows a fuel filter on each line, where can I get these normally? Also does anyone what size of tubing should be used?

[DGXSER]

Should be 1/4" tubing. I bought two inline filters from a local bike shop that specializes in off road and quads.
