4.0l TJ Fuel Pressure
« on: January 27, 2016, 10:06:19 PM »
Does anybody know the fuel line pressure of send and return/vapour lines of a 4.0l TJ?

Only asking as looking to replace mine and rather than import pre fab ones with hard and rubber tube lines. Was thinking of running goodridge fuel hose from tank to engine bay which should be good for 400psi so thinking will do just as good a job as a hard line!

Thanks

97-04 is 49.2psi +-5psi.
05-06 is about 10psi above that.

That's for the fuel supply line. There is no return line, the vapour  line won't be under any pressure worth mentioning.
