260E Stalled & won't Restart

Hi,

I would appreciate some ideas on what to look at in repairing my 1987

For a few weeks it would intermittently stall while at an idle, or while driving it would loose power for a 5-6 seconds then stall(smooth shut down). It always restarted and ran all day until recently. Last Sat. it stalled and won't restart. It try¹s to start but it seems like it's not getting any gas.

Does the above symptom point to a certain part?

Anyone have any ideas? I'm thinking it's either:

Clogged fuel filter- Where is it?

Bad Fuel pump - Where is it?

Bad fuel pump relay - Where is it?

Thank you for your assistance.

David
