Step 1

• Determine the Peak Current (A or Amps) of the fuel pump and/or fuel pumps 

• Example - Walbro 460 fuel Pump Peak Current @ 60 PSI = 15.23A (12v)

Notes

• Continuous & Peak Current differ in forced induction applications (supercharged and turbocharged). In naturally aspirated vehicles Continuous & Peak are generally the same as voltage and fuel pressure are constant. However, in some naturally aspirated vehicles may have a Fuel System Control Module which increases voltage of the push in order to increase output which will result in high current draw. For this reason, please also determine the Peak Voltage of the fuel system and/or fuel pump which can range from 12v to 16v.

Step 2

• Multiply the Peak Current by 125% (x1.25) and round to nearest Fuse Size; 15, 20, 25 or 30.

• Example: 15.23A x 1.25 = 19.03A -rounded to 20A (see important notes below)

• The size/gauge (AWG) of the wire must be greater than the maximum fuse amperage load; 15A fuse must not exceed 14 AWG, 20A must not exceed 12 AWG, 30A must not exceed 10 AWG

• To find the correct wire size, multiply the Peak Current by 150% and round UP to the nearest wire gauge

• The length of the wire must also be taken into consideration due to resistance and voltage drop factors - the longer the wire the higher the resistance.

• Example: 15.23A x 1.50 = 22.84A - In this situation,the 22.84A must be should be rounded UP to 25A (12-10 AWG wire) or even 30A (10 AWG wire) where potential resistance and voltage drop is a material factor.
