I suspect this has been asked and answered multiple times, but now that I'm ready to order new fuel hose, cannot find the right thread(s). Tanks are down, sending units cleaned and tested, new tank top seals and fill port connectors in hand (thank you Applied GMC). Just need new soft lines sizes and total lengths to get them on order this morning.
In my review of prior forum threads, I saw several recommendations to use USCG A1-15 barrier lined hose. Now that I've considered it, seems like a no-brainer. Is it?
In case anyone is wondering - I elected to re-use the original sending units and tank-selector configuration. PO installed an in-line pump just forward of the tank selector valve and activated by an Aux fuel pump switch at the dash. Strainer socks were removed previously in favor of in-line filter outside the tanks. This arrangement has given me zero issues so, if it ain't broke...

Keep in mind ALL rubber in the fuel system must be replaced, including the
fuel pump and selector switch and sometimes the vapor separator
Also seriously consider using an aux. fuel pump with switch as there is
great chances for vapor loc at warmer temperature.
Do it now, than doing it later.
