square body 5.3 swap fuel system

[coyotes33]

1987 Fuel Tank and sending unit. In-tank pump, walbro 255 is common as well as any pump from 1996-up trucks (OEM). Lines, you can either do the fuel injection rated rubber lines and correct fittings, or a lot of people do the stainless braided lines with AN fittings and adapt it into the fuel system.

Adapt them to the stock steel lines? Is there any additional filter needed since the return style already has a regulator?

[lechez71]

yes the filter is needed. you can adapt to the steel lines with a AN to tube adapter fitting. i just ran new -6 hose
