VX LS1 fuel pump question

[Glaze]

They do have an external filter.

If OP can hear the pump, it’s likely okay. Typically, they either work or they don’t.

Keeping in mind that you won’t see much pressure from an open fuel line. Perhaps the tank’s empty?

Tank is at half, what do you suggest to determine fuel delivery? Cheers

Start by looking for an external fuel filter and swap that. Gen IIs had them about half way along the drivers side chassis rail. Not sure where yours will be.

Never heard of that or seen it I’ve been under the car multiple times with diff, gearbox, exhaust and driveshaft out and never seen an external filter besides the standard one near the tank

Inside or external to the tank?

External Z156 I think, I replaced only few months ago

I'd pull it off and see if it's blocked.

I got a tank with pump off a 99 WH caprice would it fit direct into an 02 Calais
