Just thought id throw it out there.... I don't have surge tank.... And don't have any issues. But also saying that, I never let it go below 1/4 of a tank.

My conversion was done way back in the 90's. when there were no parts available, looms, etc etc. I was one of the guys that trialled the first of the pacemaker extractors for the efi heads into HZ shape.
