View Full Version : Fuel line diameter...does it matter?

08-25-2002, 06:55 PM
I noticed i had a leak from my fuel filter inlet hose, where it connects to the hard line...so I picked up some new 1/4" fuel line hose...only to realize the old hose was 3/8"...my question, does it matter? I put in the new 1/4" hose...which spans for about 8 inches.

Will that restrict my fuel flow/pressure enough to make a difference? I'm using the walbro and z32 filter, otherwise stock fuel system on SR.

it will restrict your flow yes, how much no one could tell.

The factory 240 lines did my SR just fine with a walbro intank pump. so whos to say your 8"s of 1/4" line will restrict it to 400hp potential flow...?????
