what fuel pipe should i use for inside a fuel tank as it will be submersed in fuel aswell as being used for fuel.

 

u can buy propper fuel hose from any good motor factors . they do a low pressure rubber and a high pressure overbraided rubber . although i assume it's only a pick up i would try and get some high pressure pipe . cheers Ally

 

You can use any fuel resistant pipe, for inside or outside, I use OPA, as resistant to all oils petrol/diesel.
