Precautions To Take Before Siphoning Gas (Page 1/3)
Brent7088 MAY 20, 05:41 PM
Hello Everyone -

I plan to jumper the ALDL to engage the full pump and siphon as much gas as I can out of my full fuel tank before dropping it to change out or clean the sending unit.

Here's what I had planned to do in this order:

1. Install battery, connect the cables
2. Disconnect line at fuel filter, remove the filter
3. Run a 5 - 6ft. hose from filter line to an empty gas can
4: Jump A & G pins to engage fuel pump
5. Key in the ON position

This would be done in a garage that's around 80* inside. There would be no smoking, no hammering going on, nor any electrical devices nearby that could cause a spark.

Would there happen to be any other precautions to take to prevent a fire or explosion before getting started?

Thank you in advance.

Check all insurance policies?

Wrong.

Ground neg battery term
Connect pos battery term to ALDL G
FP draws 7 - 10 amps and can drain the battery fast if you have a "full" tank.
Do Not let the Battery to Die, < ~ 11 Volt or except need a new battery soon.
Do Not let FP to Run Dry.

Make sure G is G. ALDL can be installed either way and pin layout changes for either case.
⚠️ Warning: Do it outdoors! Gasoline Fumes are "heavy" and goes to the floor and have nasty habit finding any spark, hot thing or pilot light.

Thanks Ogre - I was mainly drawing from the first reply in the small thread below, so I assume it's correct:

https://www.fiero.nl/forum/Forum2/HTML/141986.html

The battery is currently fully charged and was brand new last year.

Nope. Gall757 is wrong too and I didn't notice at the time.
Edit my top post in same thread to prevent this problem.

Brand New batteries will drain fast like this and damage them. FP don't like Low Volts either. Watch Volts and charge before gets to 11.5. Charge after anyway.
Headlight On killing them is another example for people that have vehicles w/o BCM or other things that Shut Off the HL automatically.

Geesh now I just feel like a hand pump would be the best option at this point

How about having the charger connected to the battery while the fuel pump is running?

Would help if charger is 6-10a minimum. but don't need "shop" charger/booster outputting a lot of amps.

Issue is many are "Smart Charger" and may flip out w/o a battery and refuse to turn on.
Old very dump chargers need a battery just to smooth the volts.

FP and many other motors, relays, even wiring don't like low volts.
See my Cave, Electric Motors

Is partly why many has fried FP every few years or even faster fail rate because never check wiring problems etc.
Not just counterfeit parts does this.

Ogre, I wasn't suggesting not having a battery in the mix.
