Fuel Pump

Eyup chaps, sorry to bother you again. I have a small dent int top o mi tank, from when I had it nicked. I thought that whils mi tank were off t'bike, I'd take it to mi mate who has a body shop. He's tried to pull it out, but ant had much luck. His "dent" man is there, and he sez if we take fuel pump out, he can get to it from bottom, and sort it. My question is...... is it much of a job emptying what bit of fuel is in there, and removing/replacing fuel pump? I presume I'd have to fit new gaskets/seal on replacing it?
I've looked int manuals section, and there's nowt about fuel pump removal.
TIA

 

Cheers Don.
No pics mate, mi mate has mi tank. He's bringing it back toneet. Think I'll live wit dent, as it's only a small un.
