Fuel pump replacement struggles??!!

Hey guys. I'm stumped and I'm pretty sure this is all over the forum but my search yielded nothing. Anyway I am working on dropping my tank. The skid plate is gone. The filler hose, and the other hose to the top of the pump are disconnected. I'm having a big fit however disconnecting the vent piping from the box attached to the passenger side wheel well. The green cap looks like it should come loose somehow but I'm not sure how. Any advice would be massively appreciated. Pics below.

Paper clip.

Two slots, bend paper clip to fit in both slots, pull tube out closest to you.

You do not need to apply lots of pressure.

Hope this helps.

It's just a fancy push fitting. The green cap is just a dust cover over the collet. If you can't release it by pushing on the collet through the slots in the green cap, then use a small screwdriver to pry off the green cap and push on the collet to release the plastic line. A little silicone spray may help if things are stuck.

Thanks guys. I got it. I think it was just really gunked up and didn't want to let go.

Well. Now I'm stumped. Did all this work and now my fuel pump is either a bad unit or it's not getting power for some odd reason. Now my truck is stuck at my office. Any ideas on where to start chasing this electrical gremlin?

Is there power at the pump with the key in the run position?
Fuse?
Relay?
That's where I would start.

When key is in the first position, do you hear the pump/relay kick on?

Is it an aftermarket pump?

It's definitely an aftermarket pump. I also did change the relays, fuse, filter, and pump when I did the whole project. I thought about this long and hard, and I decided that I'm not comfortable with electrical gremlins as a DIY'er. Burning my truck to the ground is just not in my plans. I had the truck towed to NTX British to let Alan do his magic.

The verdict is in. Sort of. Apparently it was a bad fuel pump that I had purchased and installed. Allan at NTX British bypassed the current tank and fuel pump somehow and the truck started right up.

Glad you figured it out. Does anyone know what a replacement for that green capped collet fuel vent tube fitting is? Mine always gives me fits. When I dropped the tank this weekend to fix the fuel level sending unit, the green cap disintegrated and the collet never released---I man handled the tube out. Still working, but I want to swap it out (probably have to cut the hose and do some magic) and wondered if anyone knew what a replacement part for that bit may be (or may be called).

Thanks!

I've had bad luck with aftermarket fuel pumps in Land Rovers, I would definitely go Genuine.
