FWIW- I have a Frieghtliner delivery truck for my business that doesn't get much use. Last time I started it, it died after 5 min. of idle. Checked the diesel tank and found it was full of rust. Spec'ing out a new tank was $450+, so for a bit over $100 I bought two liner kits from KBS- "Gold Tank Sealer". I just finished putting in the liner this weekend (3 step process with days of drying in between) and will reinstall the tank tomorrow. If the way the liner stuck to my funnel and skin is any indication it should work pretty well. Time will tell. No relation with KBS here, just thought I'd throw out another option for you.
