pressure for fuel line at tank?

What pressure does the rubber fuel line on the tank need to be rated to?

89 xj 4.0

i'd say just over the standard fuel pressure, maybe 50psi to error on the high side? i'd say any fuel line thats OK for EFI use will be fine.

id bet aquarium hose would be fine pressure wise... it would just fail eventually (possibly pretty soon) due to decomposition from the chermicals in the gas.

Thanks, Ken checked in chat and came up with 31-39. The line I got says not for MPI but is rated to 50 psi.

Grimm says the open system of the renix should mean I'm good to go with this line.

If not I guess there will just be a bit of fuel sprayed in my garage
