Are there any recommendations on new fuel lines I just had a leak and I know I need to change the lines sooner then later I am going to do the lq4 motor change when this motor dies but the fuel lines are not going to wait

I think it's common practice to tack weld them on to prevent that in the future.I started to lose oil pressure out of no where and after dropping the oil pan I found out why the pickup tube completely fell off the oil pump
Well crap!Well all my work and time for nothing I figured I would change the oil pump while I Had the pan off and turns out that the low oil pressure killed the motor so I doing the last swap now
