I would warn anyone against doing this to a vehicle you can not afford to replace. You are working with gasoline near a hot engine. Car fires are nasty ones.
Just the same, the whole idea of doing it on the old pickup is to check it out on something we can afford to have it not work on and then fix afterward if necessary. A 1992 Ford F-150.
I'll post something on FR after we do so in the next coupe of months and then test it long enough in real world conditions here in IDaho to get a feel for the results.
