I have a 20 gallon plastic tank that came with the boat. I'd like to add a second pickup to feed a fuel
polisher. My previous Parker polisher pump pulled diesel
through the fuel
filter/water separator that came with the boat using the standard pickup via a simple inline installation
plus a brass T-fitting into the return fuel line. I was never thrilled with the inline install and the use of 1 filter/separator for both engine
and polishing. Now that the Parker has failed (and replacement cost is $600+ as availability is limited) I am looking to install a dedicated fuel polishing pickup, pump, and filter/separator. Output from the pump, after it has been drawn through the filter, will use the same return line.
My first question is how best to cut the hole for the pickup? I don't want to put plastic shavings in the tank but I suppose my new polishing system will pick up the shavings? Also, I was thinking of using aluminum
pickup and bung. Would 5200 be the best adhesive
to "weld" the bung to the plastic tank? The lip on the bungs I have seen online are not very wide so I need to use something serious to hold it in place. There appears to be a spot molded into the top of the tank to put an additional sending unit but I don't see anything for an additional pickup. Maybe I am making it more complicated than it needs to be.
Comments/criticism of my approach is appreciated. I have attached a picture of my tank.
