Re: glass fuel bowl replacement

Given good, clean gasoline, the ceramic stone filter element should not require frequent cleaning, I clean mine with tuneups (every 5 to 10 thousand miles). When clean they are very non-restrictive. If they get coated with "gum", the problem is almost certainly old gasoline. The topic of how to clean the ceramic elements has been discussed before, they may be cleaned with solvent and blown gently with compressed air in REVERSE direction of the fuel flow to disloge debris from the ceramic matrix. Otherwise you're just blowing the debris further into the matrix and further reducing flow rate. Ultrasonic cleaning is probably the most elaborate and best cleaning method.

In my experience the major issue with them is that if you must service one while on the road, chances are that when you remove the bowl, you'll find the rubber gasket unsuitable for reuse as they get very brittle and often break when removing the bowl. Carrying a spare gasket (and ceramic) in the glove box is advised.
