I need a fuel tank, and trying to be future proof.

at the moment i have a carbed pinto, but I'm likely to move onto BEC in the next couple of years.
so, what features do i need in a tank?

vents, returns, breathers, senders??
not going racing, so im assuming i dont need it baffled??


any opinions?

Not knowing what a CEC tank would require, I can only advise as to BEC tank.

On our ZX12R engine, we have an internal fuel pump and sender. A standard tank will not house the height of the internal pump, therefore we have needed to drop it. We dropped it by 50mm as this then makes a more than adequate swirl pot. Fortunately!

We have used some 9mm thick plate to make a less flexible mount for the pump to sit on. We have also used the same thickness plate on which to mount the (heavily modified) sender. Using all blind tapped holes we should have no problem with leakage.

On the blade engine we used an external syphon type pickup. Using also a tubed breather with a 1mm drilled hole to atmosphere - or you can use a vented filler.

No returns on either engine required.

HTH

uhh no return needed??

every fuel injected one needs a return....

the return line is pressure less..

TKS

Not every fuel injection car needs a return, my ford focus doesn't have one.

Aaah - not so.... on our's at least - typical on most BEC.

The bike engine is fed by a pressure actuated pump - carb or injector. When the pump senses low pressure in the fuel line (typically 1 bar), the pump kicks in and replaces lost pressure.

On the ZX12R the fuel line pressure is in excess of 3 bar.

Isn't the Focus a recirculating rail system? Ford must have changed the tactics then.

Most Bosch based systems use a return with the rail pressure valve returning excess to the tank.

Hmmmmmmm, every injection system I have come across runs a return line. A lot of carb systems don't but even high output carb systems often do.

Maybe I am out of step with modern technology, but the pump control needed to maintain perfect line pressure during transient engine conditions???????how does it do that!!!!!!!!!!!!!

How many lines are there out of hte fuel pump? just wondering if its got an integrated swirl pot to single input and it maintains the pressure in the duel output lines.......
