Dropping fuel tank --

Dropping fuel tank --

Postby johnsastro [OP] » February 15th 2012, 8:45pm

2003 Astro....

So I'm want to drop the tank to install a new fuel pump, read all I could find on the procedure.

BUT... From what I've read its suppose to be an simpe procedure to remove the metal shield from beneath the tank by popping out the plastic fasteners and a removing a few clips. Not quite that easy. My metal shield is one piece held held in place by the metal straps that support the tank. The straps wrap around the shield. :screaming:

So how the hell am I suppose to remove the shield without removing the straps? :banghead: Without the shield removed I have no access to detach the fuel lines or electical connections.

What am I'm missing here? I've read nothing mentioning this set-up. Please someone advise me as I Need my van fixed..... ASAP

Thanks all.

Hmmm.

I have a 1997. There is a plastic shield wrapped around the bottom of the tank that stays put and the steel straps wrap around the whole tank. You need to unbolt one side of the metal straps and lower the tank. My tank had a thick steel plate laying on top as a protection shield. It simply lifts off once you have the tank lowered enough.

Your tank might be different but somehow I doubt it.

Well that's helpful. Still looks like the tanks needs to come down.

Mine has a metal shied instead of plastic shied.

Anyhow, If I lower the tank a few inches won't that break the fuel line/electrical connections? From what I've read in other posts, you're suppose to disconnect the fuel lines and electrical before lowering the tank.

Diagrams and advice much appreciated.

Thanks

The idea is to have a hydraulic jack with a good piece of thick plywood to cover a good sized space on the bottom of the tank ,, gently ,gradually lower the tank just enough to get your hand and wrench in there to loosen and disconnect the lines , if done carefully and slowly you should be able to do it without anything breaking ,, definitely not something to rush through , take your time and you will be fine

here is at least one thread that may help as thee are others as well

Ok then, I'll lower the tank slowly and take it from there.

I've read many threads on this subject and not one has mentioned leaving the bottom sheild attached. Nothing I've researched made any mention of the retainings straps encompassing the bottom shield. There must be a big difference between the earlier Astros and 2003-2005 models. If anyone out there has a late model Astro and done this job, please chime in. That being said, I'm almost tempted to cut in the access hatch and forget dropping the tank, but that's another possibility I'm not sure I want to do for several good reasons.


THANKS ALL,
John

No matter the year you should be able to disconnect all the lines before dropping the tank.

I have instruction on this page I built.
https://sites.google.com/site/astrosafa ... umps-tanks

I've done this once for every Astro I owned. If you would like phone support, PM me for my number.

Appreciate the help, I came across your write-up during my research.

But again this does not match my set-up. My bottom shield is one piece metal and not removable unless the straps are removed first.

I find it difficult to believe that none of the write-ups I've come across apply to the late model Astro's. From the advice I've been given, the tank has to be dropped with the shield attached. I don't see any way to do it otherwise, but I'm still open for suggestions from someone that has dropped the tank on a late model Astro.

I have done it a few times in the last 10 days or so. Mine's a 92 so its way different than yours. Everything I need access to is available with the tank installed.

I have changed out a fuel pump on a 95 suburban also. That one had no access to any of the lines without 1st moving the tank. I did exactly what was said above. Floor jack with a piece of wood to spread the load. Remove the tank straps and lower the tank enough to get at the connections. Its not easy but its possible.

I would suggest removing the drive shaft before you attack the tank. You'll free up a ton of room under there without the shaft in the way.

Be sure to drain the tank as best as you can before doing anything. Even 2 gallons in there will throw everything off balance.
