Robust Fuel System

I have a 2002 Astro AWD, VIN# 1GNEL19X32B142652.

My fuel pump has failed and I was looking online for a replacement part. I found several available. But some were qualified with the phrase "w/o robust fuel system" or "except robust fuel system sender". I searched this forum for "Robust Fuel System" and found zero matches.

Can anyone instruct me how to determine whether or not my vehicle pocesses the robust fuel system (sender) ?

Thanks you in advance for any and all help.

I've never heard of a difference between fuel systems on an Astro.

You might try over at AstroSafarivans.com. There's very little those folks there don't know.

OldMaster, are you around? What's this thing he's talking about?

Apparently no one knows. I asked @ ASV. No response...

AFAIK, the "robust" fuel system used a three-line external filter, more stainless, and no brass. It was intended for use with higher levels of alcohol.

Alcohol or for leaded fuel? I found one reference to it being for vehicles intended for export from the US to locations with leaded fuel.
