We usually go with an 89-91 stock tank/pump system. The well cell is nice, but more expensive when set up correctly. Hot setup is well cell with black box accumulator and pump, about $750.

Buy a fuel tank from an 89-91 325i. Use the fuel pump for that model, no secondary pump.

i second what james said. i was having all kinds of fuel delivery problems. couldn't run it less than 2/3 full without getting starvation in right handers. got a new 88-91 (used) tank from bimmerssouth and a new fuel pump. in practice last month i ran it down to 1/4 with the low fuel light coming on. no starvation at all. tank was about $100. was in near perfect shape when it arrived. no rust. bimmerssouth is in georgia and does not appear to do anything that has rust on it. the old one i took out has a rusted out cross flow pipe.
