EFI fuel tank module for stock tanks
Last week I stumbled upon an Spectra Premium EFI pump/sender of an E-body on Amazon too cheap to pass up. Its Spectra pn:
SP196A1H ($175 on RockAuto). It comes with a genuine Walbro 255lph pump.
Just out of curiosity, I fished it into a spare A-body fuel tank I had laying around. It sure seems to fit awfully well and could be a reasonable alternative to a TANKS setup.
There's still no baffle around the pump, so as it is, low fuel levels may suck air but a Holley Hydramat would take car of that.
