Fuel Pickup and ASV Replacement, Summer 2019

In this video, I document the replacement of the fuel pickup assembly and anti-siphon valve on the poly tank of my 2002 Key West 1720 CC. The video is 14 minutes long and shows step by step what I did from start to finish.

This project was one of two I tackled at the same time on the KW. The second was the removal of several quarts of water that had found its way into the tank due to a sending unit that wasn't properly sealed to the tank (my fault). This is documented on the Key West Boats Forum.

I have heard that some of these anti-siphon valves when corroded will break off if you attempt to remove it from the fuel pickup fitting. I suggest you simply remove the fuel hose from the ASV, then remove the fuel pickup from the tank. If the ASV is in that bad a shape, the fuel pickup probably is also and both should be replaced.

I will probably spray some Fluid Film over this fitting to help reduce future corrosion.

Edited 04/2021: In a Facebook group that I belong to, a member who goes by Christopher Kess In-Ger posted his trick to keeping a nut busting solvent around the fuel pickup tank nut. Quoting his post: "After 3 days of spraying the fuel pickup with pb blaster and pretty much bending a basin wrench trying to get it off I took a 3” pvc pipe cap and drilled a hole just big enough to fit around the fuel pickup fitting and siliconed around the bottom hole of the pvc cap and stuck it to the tank and filled it with PB plaster after letting the silicone dry for a day. I then lightly tapped it with a hammer and tried to turn it with a wrench every day to help the PB blaster work it’s way in. It Finally came off today after 5 days of soaking using a 3/4” crows foot wrench w/ 10” extension." Christopher used the PVC cap as a cup to hold the solvent, with the silicone to prevent the solvent from touching the tank. Excellent idea, Christopher!
