Thats a crimp clamp the same as CV boots use, not a clic-R. It needs a slightly more specialist tool, but a worm-drive hose clamp will work fine.

A smear of engine oil or petroleum jelly will work on the o-ring.

The large seal for the top of the tank should have a lip at the top, like an upside-down top hat.

Oh, the plastic pipe is the return I think, which should just be tucked in to the fuel pump housing.

(edit - don't use petroleum jelly on rubber. That was terrible advice and is retracted!)

Glad to be corrected by a real expert.
At least I only said "looks like".

I feel like a idiot because I didn't look on the hose clamp itself as the brand name and size is engraved on it. The name and size on the clamp is Oetiker and 15.3. With this I did a google search and the actual name of this is called a ear clamp and you don't need a special tool to install them. The tool that I bought is a end cutting pliers. Tomorrow I will stop at the hardware store to see if they have this ear clamp in stock as I need to buy a couple more. Here is a couple of links for the ear clamps and end cutting pliers for reference.

The hardware store that I went to didn't have them in stock and was told it'll be 2 - 3 to get them in. So I didn't order them as they are closed on the weekend and they are closed when I get back in town from work when it would come in if I had them order it. I just ordered them online instead. So I'll have to wait some more before I can finish this fuel pump job.

I can recommend MolyKote 111 to use to lubricate the o-ring. It's made to be o-ring lubricant for situations like this. It's great stuff!

I wouldn't want to put silicone anywhere near the fuel system, and especially not inside the tank. It will do bad things to the O2 sensors amongst other things. Something fuel-soluble is best in this application

Good thought! I hadn't even considered that.

Is engine oil really safe to use in fuel-soluble application? I've heard that using petroleum jelly can become a problem with rubber o-rings?

I would use oil since oil and fuel are basically the same thing. A tiny smear of oil on the o-ring will safely dissolve in to the fuel and be burnt off in normal combustion.

Say a fingertip of oil on the o-ring is 1ml, dissolved in to half a tank of fuel thats a ratio of 50,000:1 which is totally insignificant, similar to what is coming in as vapour from the crankcase breather.
