Well I'm just setting here being stupid this morning. Many of you have heard me whine and grumble etc. This rant at my self is because I put five gallons of regular gas in my 54'. Six weeks later have to clean out everything. Truck ran like *#@%. Sewing machine six weeks ago to a black fog and 4 of the six cylinders alternately waiting their turn to ignite. The fuel line is setting right there would a high quality pet cock valve work if I put it in front of fuel bowl? That way if I'm in a pinch if I can't find a blue pump at a WAWA on the road trips the antiquers go on in sunny damp Florida I can park it back in the barn and run all the gas in the bowl out.
