Fuel Tank Baffles
Does anyone have any real life experience of how many baffles you need in a book dimensioned fuel tank? I want to use the car for track days so I am
concerned about fuel starvation.
The engine is a 1600 Xflow with a twin choke weber and I hope to use the mechanical pump on the engine. The fuel will be feed through 8mm copper tube
and rubber flexis at each end.
 
Fuel Tank
My fuel feed is from a pipe at the very bottom of the tank about 2 inches in from the driver's side end of the tank.
I have one vertical baffle roughly 8 inches in from the same end as the fuel feed (you can see where i've cleaned up the weld.)
Has anyone ever had fuel starvation problems with a similar setup?
Cheers
Gary

Put a double height 50 litre in mine and had to baffle twice. Going around corners or accelerating hard will show the guage as empty very easily and
takes a while to come back.
Would advise that tank foam a very worthwhile investment if its not too late.

Hi for track use you always put the pick up on the out side of the corners ie in the uk the left. Then the best option is to bore a 1" hole in
the bottom of the tank on the left side and fabricate a box the size of a packet of fags and weld that to the bottom of the tank so that the hole will
feed the box with your pickup pipe coming out of that to suit the desired run for the fuel pipe. Then pack up the right hand side so that the tank is
levell across the car again. And remember to put a breather pipe on the top of the tank with a proper rollover valve type breather not a small hole
drilled in the filler neck. You will still need some baffels in the main tank but are now only needed to stop the bulk of the fuel moving so not quite
as important as without the new sump on the base.
