Thanks guys,
Yes Pete, they were soaked in a chemical solution ( not acid) , drained, then pressure washed, one tank needed two cracks at it it was so bad but in the end they came out a lot cleaner than I expected. Some minor specks of service rust in a few places but so much cleaner.
Cleaning up the feeder pipes and replacing the sender units they'll be good as gold. I'm not bothering with sorting out the mid mounted tank as I really can't see myself using two long range tanks, a couple of jerries then drawing on the 80 - 100 Ltr rear tank.
Not unless we have fuel strikes 😊😊
Cheers,
Mick
