FW: Gasoline in the oil

I stuck with the stock pump, just got a new diaphram. I got the tanks boiled out and tested it. Ran fabulous. Took it out on the highway and it started hesitating with a muffled burp at high speeds. I thought it was electrical initially since the tachometer dropped with each 'phup' although speed remained the same. I popped the hood and noticed that air is going through the in-line filter just in front of the Stromburgs. This was what was happening when the diaphragm went out (to a much greater degree) and I got the gas in the oil. Did not run it enough miles and the oil is too new to see or smell if there is gas in it. Don't want to run it more in case the new diaphragm is leaking. Any suggestions?

Dennis-

I think I got it pretty soon. Looks like it may have been exacerbated by an extremely dirty gas tank and line system. There was a filter in front of the pump that I believe may have clogged, created a vaccuum and perhaps help send the diaphragm over the end. Have decided just to replace diaphragm and stay with good old mechanical based upon advice of the list and my own inclinations to originality. Getting tanks boiled and blown as we speak. Hopefully back on road by Friday as the regular car went in for body work today (got damaged during Richmond hurricane or whatever that was). Not a good car week (did I mention that both front rotors are warped and that the left caliber need rebuilding and new brake hoses, sigh).

Be careful in choosing the proper electric pump. Many aftermarket pumps put out way too much pressure for stock carbs to handle - one such pump came on our S3 and will soon be replaced with a stock pump! ............................................................
