coming back to "engine breathing..." Tuesday, 11-Jul-2000 15:56:49 Message: 196.7.203.48 writes: Has anyone attached a breather pipe to the fuel pump hole after adding an elecronic feul pump? When you run your breather pipes to the carbs, do you run all the pipes into on box and the to one/both carbs or do you do it differently, say, both valve covers to one carb and the oil breather to the other carb? Just trying to get ideas for "free" HP. Thanx Tony Z

The right valve cover vents into the very bottom of the breather, so that any oil that does accumulate inside can drain back into the motor. I'm still using a mechanical pump, so haven't yet had the opportunity to vent the case from that area. Craig Merrow

Use a vacuum guage and keep the vacuum low so you don't suck out oil...5 lbs seems to be the amount that is accepted by the V8 drag guys. Restrict the amount with an orfice washer. The fuel pump hole is ideal. Ken "Kghia" Swain. Ken Swain

For the valve covers I installed those lil air cleaner type oil vents on the back. This way I don't have to run hoses to a breather box and drill holes in my back tin plate. I got one of those CB performance oil filler breather box combo. I will run a line from the fuel pump plate to the bottom of the oil filler box. From the top of the box I will run lines to my air cleaners. Chad
