first time down the track advise?

No special tools, care must be used when removing and replacing the sender ring, as you know, sparks and gas fumes aren't a good mix in certain circumstances.

When you do replace it, KEEP the old lock ring and use it, the new ones are pure crap. Not sure about the 3/8 line fitting, as the factory stuff was 5/16 line.

IMO, if your gonna go to the trouble, upgrade the pump as well with a Carter unit. 120 gallon per hour

Carter M6270, Carter Strip Super Fuel Pump | Carter

Probably want a regulator as well, these pumps can push 8 PSI.

That ^^ is what is going on my build.
