Just re-read your post, hence this edit.

From my "studies" the surge tank is there to provide a fuel buffer, especially in carb -> EFI converted vehicles. A normal carb will have a "built-in" surge tank. Most carb engines were supplied by an engine driven mechanical pump. The flow from that pump will pick up as the engine revs, hence the need for the buffer.

I dont know about the bafflers. I have one in my tank (I saw it today), but has been partly damaged during installation on the intank pump. My engine can be starved during cornering (1-2 secs), but only if I am down on 10-15% fuel in the tank (and I hardly wait that long to refill)



BTW, i had my Van at the garage today. When we removed the main fuel tank, there were about 200-300g of silicone in the tank!. Being there for some time it had turned into a couple of big jelly fish. No wonder that my engine would be starved after a time.

We removed the intank pump and installed a inline bosch pump. Before getting to that pump, there is a new mesh filter that I can check and replace when needed. What we also found was a "bend" return hose that basically prevented return flow to the main tank.!

Now everything have been replaced. Now I have: suction from the tank (no intank filter). An inline filter (a Mercedez plastic mesh filter). A Bosch inline fuel pump. An additional fuel filter (1/2l canister. I dont know if it is official Toyota). The fuel rack. The return flow.

After the first test drive all problems are gone and the engine is at full power under all conditions.

I wonder from where the silicone came. I dont think it is from the garage that did the conversion (far too much). I have a feeling that I might come from a refill at a new gas station with newly installed pipes and pumps. But anyway, I am happy that I got rid of my "jelly fish".

EDIT:
(I saw a nice mod in the garage today. A BMW 535 with a 1J Twin Turbo engine. The engine work was very nicely done. I asked for the price and got a surprise... 290K Thai Baht which equals about 8K US$. Considering....!!! (It needs painting, someone gave it a "key" work). But very cheap).
