Fuel tank sender, lines, replacing.

[w2much]

I just put in an inline filter , glass so as to view what was going through. I will put in a better fuel water seperater later. To my horror nasty bits of crud and moisture could be seen. My built in 80 gallon plastic tank has a bit of a low spot on the top where the sending unit bolts on. It still works but is quite corroded. It collects water around it because it has become a low spot on a large flat surface. I am thinking water may or probably is seeping in from the pool which collects there. A sending unit is only about $40.00. I am curious as to the small bolts which hold it in place will react when I try to take them out. If they break I am in trouble. Are there metal threads or what holding them into the plastic? This tank is in a 1996 Seaswirl Striper. Do plastic fuel tanks get polished? Or would a fuel water sperater and an inline filter be a safe way to go.Thanks for your replies.

Ironically, My '98 Seaswirl 21DC has the same issue on it's 63 gal plastic fuel tank. I took the sender all apart and cleaned it up and sprayed it with corrosion guard, and plan to monitor it.

Those bolts should be removeable. Some plastic tanks have moulded in "nuts", but I do not remember what my tank had.

do it, and with an 80 gallon tank get the right filter on it. serious you will break a bolt in a plastic tank. those big tanks get condensation build up in them. that makes water.

Fuel water seperater is next. I guess I am just going to have to open the can of worms when I replace the sender. My stroke of genious, or Jerry rigging(my name by the way) will be to try to jam a plastic PVC rod near where the sender is inside the tank. My thought is that this will raise and hopefully eliminate the low spot on the top of the tank. Will post when done.
