We have been trying to track down a small fuel leak for awhile now and finally tracked it to the fuel filter housing. As we where checking this out we realized we had a small rear transmission seal leak. We decided to remove the transmission and reseal front and rear seals. While out saw there was a small amount of oil in bell housing indicating a small leak in rear main seal.Replaced main rear seal as well. Replaced coupling as well while apart. Knowing our plans for continuing to cruise we will continue to maintain ...upgrade Brisa as needed along the way. Next.....the fuel tank!!!
