RB20 and RB26 injectors are both top feed so interchangeable. RB25 are side feed.

Need to match their impedance.
Rb20 is top feed, high impedance (13 ohms) 270cc.
Rb26 is top feed, low impedance (3 ohms) 444cc.
R33 Rb25 is side feed, high impedance (13 ohms) 370cc.
R34 Rb25 is top feed, high impedance (13 ohms) 370cc but totally different shape to 20/26.
So 20 and 26 can physically swap but you'd need to mod the resistor bank wiring.
