Stumped - non-starter, fuel pump issue?

[Fozzy]

Going to have to try and get into the tamperproof casing, think that requires the pump to come off again. Why do these cars have to cause so much trouble.

Half a tank of fuel and had plenty all over me when removing pipes from the filter housing.

Im currently by passing the fuel filter housing to eliminate an air leak from there also, changed the grenade also
