I'm having a nightmare at the moment with the 7.5 amp fuse on my van mount flow controller. The connection is forever coming loose and stopping me working. I've never seen such a horrible fuse holder and connectors. It's the little blue clasp type fitting with the flat fuse. No matter how i try and connect it the thing always seems to work loose. Does anybody know if this type of fitting can be changed to the more normal small cylindrical type fuse with appropriate connectors?

Go onto EBAY and tap in 'waterproof inline fuse holder', theres loads to choose from, along with the 7.5 blade fuses
