Fuel tank rattle

[Simon Underwood]

In my ongoing bid to rid my 1975 Spitfire 1500 of the noises it shouldn't be making, I've moved on to the rattling noise that's coming from the fuel tank. It's quite unpleasant and seems to resonate at certain engine/ road speeds. I've had the sender unit out, and you can knock the tank and the rattle is still there, so it's not the sender. I'm wondering if it's the fuel pick up pipe touching the inside of the tank, or the nut not being tightened enough, allowing the olive on the pipe to vibrate in its seating, which I'm going to check over the weekend. The thing that confuses me slightly is that, according to the parts drawings I've seen, the pipe appears to be in two parts, the straight part inside the tank, and the shorter pipe with the 90 degree bend on the top of the tank. This seems strange to me, shouldn't it be just one pipe? Can anyone enlighten me?

Thanks, Simon

Pipe is a single piece (p/n TKC5153) vertical upwards from the pickup to the nut, then a 90 deg bend, then it connects to a short(ish) flexible section (p/n 144938) then it connects to the rigid pipe that runs through the floor and forwards under the body.

Thanks, I thought it had to be one piece, but the drawings make it look like two.
