Default Fuel Pressure...1988 Dodge Dakota...3.9L/Auto

All,
My fuel lines have all decomposed. to the point of leaking in numerous locations around the engine compartment. The areas around the fuel filter were already replaced and the fuel pump area when I dropped the tank for new fuel straps and filler neck looked newer.

Anyways in all cases I have not see many hose clamps. The tank lines contained numerous (doubled up) clamps. The Fuel filter had a single clamp on each side. The hoses in the engine compartment appear to have rusted away. I have seen single ones around the TBI carb.

The question of point what kind of pressure is going thru these lines? Do I need high pressure injection hose and double clamps?

I will probably buy the injection hose regardless as my local Napa has it super reasonable as the farming community has them buying it in bulk constantly.

Thanks everyone,
Chris

I wanna say there is about 40psi running thru the fuel lines. At least that's about what it is at the fuel rail. Shouldn't take beefy clamping.
