Fuel Tank- In tank, in line or Swirl Pot? You decide!

Gentlemen,

I am at the point in Woodys build where it has come time to spend some hard earned cash to enable his LS heart transplant.

Therefore, I am looking for opinions and guidance on that old thistle… fuel tanks.

Currently I have the tank in cab, I really don't want to move it to the back of the truck for a number of reasons, the biggest of which is cost. Yes, I know that a tank is not that expensive but factor on the cost of shipping and duty and it just becomes a case of I would rather spend my dwindling pot of gold somewhere else. Not saying i wont have a rear tank in the future but the $800-900 landed cost would be better spent on something more interesting. Like Turbo…

Anyway, as I see it there are two options, possibly 3.

Option 1) Put a sump on the existing in cab tank and run external pump etc.

Option 2) Put an intank pump and pick up as seen else where on the board.

Option 3) Use a swirl tank.

So lets talk about option 3.

My plan would be to use a low pressure pump to transfer the fuel from the tank to the swirl pot. From there I would use a Bosch 044 High pressure pump to a Corvette regulator with a return to the swirl pot.

Thinking is that a 2L pot should be large enough.



Swirl Pot and pumps, regulator and filters I am thinking of mounting on the outside of the chassis between the bed end and arch, will use some thick wall tubing to provide protection from side impact. Passenger side looks favourite.

Total cost for this solution is going to be about $350, the only extra expense over option 1 and 2 is the cost of the lift pump and swirl pot, both of which can be picked up for around $150.

Other than cost the only other real advantage for going this route is that I am pretty much ensured that the engine is going to have plenty of fuel at all times and I doing have to start modifying the existing tank and risk making leaks and fumes.

So, can anybody see a flaw in my plan or should I stop trying to reinvent the wheel and go with Option 2?.

Comments welcome!
