a write up is necessary.

very sweet though 98ctr. Never seen something like that before. seen fuel cells up front, but not a surge tank.

because the sump is the lowest and at the rear most part of the tank so during acceleration the gas move back towards the pickup. The drian plug isn't an ideal place for a pickup.

Surge tanks are a popular solution for people who convert from carbs to fuel injection.

I don't think you understand the way it works. There is zero pressure in the surge tank, all the extra fumes and gas is routed back to the gas tank.

you sure about that Stephen? the idea of a surge tank would have there be no pressure, but in all the ---- i have seen you are suppost to feed the surge tank with a low pressure high flow fuel pump. your running it wiht a high pressure high flow pump... its ment to run at like 255lph @ 43psi with 14volts (not 100% sure, but close). so i thnk that that tank will be pressurzied...so the "extra" fuel that goes back to the tank will be pressurized a good amount im sure...

there is one on my GTI also, it runs a low pressure pump like 7psi to feed the tank and the high pressure pump...

i have thought about the size of the tank before, on a 15sec or so pull at like 400whp will take about a liter or so of gas... plus the back pump will be still feeding some gas, and the return will be going back into the tank..... i think Stephen;s tank is fine...
