Transit mk8 wiring problem

[Rower21]

Hi everyone im new to the site...i have a 66 plate transit hightop...it keeps blowing number 24 fuse 7.5a which then causes it to cut out...when pluged into diagnostics it comes up with fuel related faults...replaced the fuse again runs fine on the spot but when driving will randomly blow fuse and cutout.

Any help would be greatly appreciated

Thanks justin
