Well looked at doing this today and hit a hurdle straight away.
Got my etb sender,got connectors,got tools.
Original sierra sender has pipes for fuel to exit tank to go to engine,new sender is exactly what it says ..no pipes
No pipes at all.
What do I do now.?
Any ideas

What fuel tank are you using? Has it been used? Could you just buy a different fuel sender? Could you drill a hole in the tank and weld a outlet on the bottom?

When I upgraded the instruments back when I had my hood, I just cut a new hole for the new sender and continued to use the sierra sender with the pickup and return feed.

The tank is the original robin hood tank using the donor sierra sender.

Didnt want to get into drilling a new hole neither as that means draining and removing the tank..

New sender is etb to match the etb gauge
