Anybody used one or seen/heard one in action? Looks nice with feed return and vent lines and a gauge sending unit and includes a Walbro pump good to feed a 500hp engine. Other forums seem to have decent feedback, but of course I'd like to check here first before pulling the trigger. Bonus for me is that it ships free from Amazon, and is more than 200 bucks Canadian cheaper than an Aeromotive tank and pump combo. Spectra part number is: GM201FI Their description is that it is made to retrofit F.I. to 78-81 F body with all lines in stock position. All thoughts welcome. Brent.
