fuel pump

hey all i am going to fit my new fuel pump and filter but just wanted to ask if there is anything i need as i have found that my car has NO filter at the min and cutting the pipe and using a stranded juberley clip just seems to easy ? i have a mk3 astra but the new pump is a external 1 not 1...

bought this last year and had it on the last cav worked perfect i got it out of a vectra b that has the msd badges on it heres the part numbers on it 0 580 453 465 BOSCH 12v 014 970-22 £25 posted (first class recorded) thanks gilly (pics uploaded soon)
