Have recently completed my surge tank setup with teflon braid, 044 and low pressure (pump suction side) filter. No smell, easy to set-up but was very far from economical. Prob over 500 in fittings, plus tank, pump and the filter was 150odd. Im about to re do it with a second 044 now im running out of fuel and will be doing it all with hard lines, not only for cost but imo it looks much neater and I will be taking the opportunity to replace the old fuel lines under the car with new ally hard line also (the line itself is dirt cheap).
