Can won't start :(

We replaced the fuel filter and part of the main fuel line coming from the filter now our van won't start. It sounds like no fuel is getting to the engine.
We have triple checked the wiring and it is all good.
Any ideas? Is the fuel sender very sensitive to the length of the fuel line going from it to the fuel filter?

This is a 2007 piaggio porter van.

I am sad

Is it a canister type? if it is it will need filling with fuel fist to prime it. Back fill with fuel and give that a try. Also try with the fuel pipe off just turning the ignition to number 2 on and off to get the fuel pump to surge the fuel up the line, no need to actually start the engine. If none comes out you can suspect the fuel pump which should make a noise.

Sweet, thanks so much. Managed to get it running again.
...Now for the hole in the top of the fuel sender

metal weld epoxy will get you out of trouble if it is just a hole you are talking about until a replacement can be had? even halfrauds sell that.

That stuff is awesome! Will patch with that until my other tank is restored
