Culprit

Is this the culprit?

For a while now the AC has been picking up rubbish from the fuel tank, and clogging the pump filter. There’s two intakes that enter near the top, and extend down towards the bottom where they meet the gauze sleeves of these drain plugs.

Unfortunately, this gauze filter was bent a while back, and subsequently straightened out hastily. I thought all was good, until we were plagued with fuel problems. Further investigation reveals that it has a hole, and is full of gunk inside the filter. This will cause gunk to be drawn into the intakes and up to the pump, and may explain why the pump filter is getting clogged all the time.

Time for some cleaning and soldering!
