New fuel pump assembly , walbro 255lph TU432HP . replace the fuel line?
I just got my walbro 255lph TU432HP complete assembly . The fuel line it comes with is the plastic one. I have heard of this cracking or collapsing causing issues and replacing it with some high pressure submersible fuel line. Is this recommend to replace this before I through it in there or is the one that comes from walbro OK?
if I should replace - how to pull the line off? it seems to be on there extremely tight . so tight I feel like I have to actually cut the tube.
thanks

I wouldn't think it needs to be too flexible? the bucket is pretty stationary no?

so , like you mentioned in your first post, you said that the plastic line is better vs the thicker high pressure submersible rubber line.
I am curious to hear others opinions on this.

I have read that the ribbed teflon hose is actually intended to smooth out the pulses in the flow.
edit: Found it in the service manual:
Fuel Pump
The fuel pump is mounted in the fuel sender assembly reservoir. The fuel pump is an electric high pressure pump. Fuel is pumped to the fuel rail at a specified flow and pressure. The fuel pump delivers a constant flow of fuel to the engine during low fuel conditions and aggressive vehicle maneuvers. The powertrain control module (PCM) controls the electric fuel pump operation through a fuel pump relay. The fuel pump flex pipe acts to dampen the fuel pulses and noise generated by the fuel pump.
