Pierburg pump.
7.21287.53.0
Self priming to 0.6m (no surge tank needed)
Silent
External
Used on a few 1.6 swaps now ran faultless for 100,000kms
That would be cheaper and easier than a tank swap, still just run a ryco style fuel filter between tank and pump and the air that gets trapped in the filter doesn’t bother the pump when it sucks it in ?
