Fuel line repacement

Has anyone replumbed the fuel lines on a dual tank OBS with AN lines and fittings ?(mine is a 1993 F350 7.5 gas)
Would like to keep quick disconnects for stock filter and pumps.
thanks,
GP

I’m sure you could. I had to make a PTFE pressure hose from the DFR to the fuel rail on my ‘89. If your hoses are brittle and falling apart, another option is to buy new nylon hoses from Bronco Graveyard.

Thanks for the reply.
Did you cut in a stock style fuel filter ?

I have a different fuel system than you do. The only line I made went from the filter to the fuel rail.

I have the lines with the plastic retaining clips at the fuel
filter and spring lock connections at the fuel rail. You should be able to find what you need.

Why not replumb with what stock is/was?
Why do you want AN fittings?

One of the big aftermarket companies, maybe Earl's or Russell once made AN fittings to Ford quick connect fuel connectors.

It's been some time since I saw them offered.

Asked and did not get an answer. In my case I needed a custom hose.
