1983 911sc gas tank flush?

[Dave Kost]

I am in the process of cleaning out the fuel system in my newly 83 sc with CIS system.

I pumped out the gas thru a cheap see thru filter and was surprised how little soot was in the tank. The gas was a little cloudy. Pulled off the center filter in the swirl pot and the bottom part of the filter mesh had a fine silt on it , so I decided to pull the tank. Stuck my finger thru the filter opening and there is a small amount of brown- tan silt in the bottom of the swirl pot. DO I NEED TO GET THIS OUT?

I would like to run some fluid thru the swirl pot ( not gas ). Thinking of going thru the return line and out the pump exit and thru a filter, maybe circulating a 1/2 gallon of fluid.

Or am I over thinking this? Just dump in a half gallon of gas and swish it around and then dump it out.

What can I use other than gas?

The fuel pump was replaced by the PO shortly before I bought it. It started making a noise once I got it running, sounded like the pump was cavitating but only under load.

Any comments would be appreciated

I like this idea. Dump it into a five gallon bucket with an old t-shirt to use as a strainer. Repeat until solids are gone.

Something like Seafoam or lacquer thinner (gallon cans) will chow on any varnish. How do you know when sparkly clean? I like this too but the time investment goes way beyond just getting rid of the silt.

Has to be plenty of members that have done things to clean tanks.
