Replacing 20 gallon saddles with 16 gallon saddles - The 1947 - Present Chevrolet & GMC Truck Message Board Network

focusedontheprize · 12-23-2018, 11:04 AM

Currently my 1986 C30 has dual 20 gallon saddle tanks. I have found debris and crude in the lines so I will be completely replacing the fuel system in the truck. I have ordered new lines and came across a great deal for 2 brand new 16 gallon saddle tanks.

I know the 16 gallon tanks are shorter and imagine the filler hose will be longer, but is there any other differences I should be aware of?

Thanks.

need longer filler hoses or the factory metal filler hose extensions i have these i just removed from a 16 to 20 swap on a 2 tank truck .

frame holes for the bracket might not be there so you might have to drill them for 1 of the hangers .

otherwise bolt them up and go .
