yesterday i converted to an electric fuel pump and got to block off the hole in my head where the mechanical one was. i also made my webers float bowl vent into the fuel return line going to the gas tank. i had some problems with the fuel pressure regulator so for the time being i removed it. the weber 38 runs GREAT with my universal electric fuel pump which is rated at 4-7 psi. the weber only wants 2 to 3 but it runs great and has no problems. ill have to get pics later of the couple things i did, im pretty excited to try it out on some hills and see how it does.
as for you weber guys, re-routing the float bowl vent is REALLY easy. if you are knowledgable enough to put a weber on your truck in the first place, you can do this little trick. you can see the port on the outside of the carb that you will use. its right on top of the float bowl. just get a piece of 3/8th OD copper tubing, sand it a little where you will insert it, and stick it in the hole. i used red loctite on the outside of the copper when i put it in the hole because it hardens up nicely like glue. it works GREAT for this, sealed the tube in there nicely and holds it strong, and its heat resistant. then just route your new tube into your fuel return line. if you dont know which one it is, look at the top of your gas tank and follow the line up the frame rails
