SZ Heavy Duty Fuse Holder Kit

This upgraded heavy duty fuse holder is intended for those running high amperage and high heat electrical load fuel pumps and e-fans. Walbro 450+ series fuel pumps add high stress to the wiring. On relay kits using 10 gauge wiring and fuse holders we've seen the supplied parts begin to melt. This kit uses 6 gauge wiring that steps down to 10 gauge with the use of reducer barrel crimps. A 40 amp fuse is included along with the ring terminal meant to connect to the battery's positive terminal\wiring. The kit's large size can adequately handle the load\heat. This will require the use of a HD crimper on the last wire coming off your existing relay battery power wire. We HIGHLY recommend running a 10 gauge wire from the negative battery for fuel pump ground to ensure best performance from your fuel pump.
