Custom fuel system- add your ideas/input
I am starting to put together my list for a custom fuel system.
This is what I want to have:
-Sump in tank
-High quality fuel/water separator(s)
-High quality fuel pump
-High quality regulator
-Stainless fuel lines (or Parker high abrasion resistant lines)
-Non corrosive fittings (I dont want aluminum into steel, vice versa)
Ive come up with a lot of the parts I will need.
A few things maybe some of you may already have in the memory bank:
-What size banjo fittings are used on the fuel inlets to the cylinder heads?
-What size banjo fittings on the back of the heads for the return?
I think I want to use socketless style fittings. All the hose manufacturers carry them, and are rated for up to 250psi, diesel, etc. Besides not finding the correct style hose ends, anyone see a reason not to use them? I am having trouble locating the appropriate banjo style fittings in socketless (probably not searching with the right words).
This is just me starting this whole process. Criticism is expected and needed.
I have built fuel systems for race cars, bikes, and outboards, so this isnt my first rodeo. But this is my first diesel (unless you count my Wiggins Marina Bull fork lift at work- lol).
But from my quick research it seems like the system will go like this:
Tank--Sump--Line--Filter--Feed Line--Pump--Feed Line--Y--Banjo-Heads--Banjo--Y--Return Line--Regulator--Line--Tank
