IMHO,, The Correct Way To Do the Fuel Supply Hose Replacement
& The Way that I Always Recommend that It Be Done is to Run 1 Single
Length of High Pressure Fuel Injection Hose frm Fuel Filter to the Splitter
"T" by the OilBreather Tower ~ You end up with Only 2 Possible Leak Points
Instead of 6 & a Brand New, Really Strong, All 1 ID Hose ~
(I use 225PSI Gates 5/16) It is Pricey Hose @ about $3.50/Ft but only takes
about 6.5Ft >> Way Cheaper than an Engine Fire ~
Also >> I usually DoNot run the Hose back through the hole left by the
removal of the Old Plastic PasThru Fitting, I just run it under the FireWall &
then it aligns nicely with passing under the Intake ~
