Default 3 bad fuel pumps

1995 Astro van for the past 3 years i have to replace my fuel pump 4 times,
in the past 10 years i own this van before the last 3 years i never have any problem with fuel pumps before,
there is a new fuel filter and the spider was replace 3 years ago when the van reach 140k miles i have 160k now 3 fuel pumps in the past 20k miles
I just got home in a tow truck and i can hear there is no pump noise i got under the van with a test light and there is 12 volts, so no relay or fuse problem

What brand of pump did you buy? The cheap ones don't last. Always buy Delco or Delphi.

Yep,
It is well known the non OEM brand pumps fail prematurely.
Spend the money on the real deal and forget about it for another 100k miles or so,

I had a 95 Safari that ate fuel pumps too. I've always replaced them with the AC brand, but they failed anyway. I've also replaced the spider assy 3 times. It got very annoying when they would go out.
That old baby got me 318,000 miles, before antifreeze started disappearing, so I retired it.
Since then, I've owned a 96 Astro with 245,000 miles, and now a 2000 with 290,000 miles, and you know what? Its the best one of the three.
I got 24 mpg the last long trip I took. The motor with the throttle body injection, has more pep and get up and go, than the other 2, with the CMFI.
I have not had to replace a fuel pump, or a spider assy (on the 96) .
I believe now, instead of replacing the entire spider assembly, you can get individual poppet valves for the plugged up ones in your spider assy.
I always thought why change the whole thing, when only one would plug up.

How do I change fuel pump on 1995 Astro Van? Drop tank or an easier access?
