Aux. Gas feed

I routinely camp with my Honda 2000 generator. I've heard of folks "splicing" off of their vehicle gas tanks to refill their generators. I sure would love to try this.

I drive a 1996 suburban 2500 with a 350 vortec.

I would prefer not to have to drill into the tank to add hardware.

I seem to remember reading about putting a tee with a valve somewhere with a flex hose than can be put in the tank of the genny.

I am not talking about running the genny from the vehicle tank, only refilling it.

Thoughts?

That truck has a schrader valve at the motor by the distributor cap. When the ignition is on the fuel pump is supplying fuel pressure. If you connect a fuel pressure gauge like this to the schrader, you can push the release button with the ignition on you can direct the drain line to the generator tank. http://www.amazon.com/dp/B0006V2BI2/?tag=atomicindus08-20

As a bonus you will have the gauge to diagnose the truck when your fuel pump fails.

I have a 96 305 Express van with almost a full tank of gas , I want to scrap the vehicle but I'd like to get out the 100 liters of gasoline first. what would I need to do this on the cheap? ( to tranfer the fuel to another vehicle )

You could use the same gauge i listed above, if you happen to have one laying around i have been told that the schrader valve is that same as found on old r12 refrigerant charging hoses. The schrader on the 96 305 should be in the same location by the distributor

If your scrapping it, just cut a fuel line and attach an extension hose to reach your gas can and then turn the key on. It will pump the tank dry.

Another idea on that note would be to use a valve core tool to remove the core from the schrader, slip a piece of hose over the schrader and put the hose into your container

You would have to bypass the fuel pump relay, as turning on the ignition only cycles the pump for a couple of seconds. Depending on your vehicles filler neck, some have a flap door on a spring usually older models, newer cars have a ball inline to help situations like roll overs etc... so it makes siphoning impossible . I have a older toyota pickup which has the flapper type filler neck and I simply put a 1/2 hose and do it old school. Be careful putting gauges on the fuel rail, as they will break and spray fuel all over your hot engine bay , not a good thing...... I think siphoning will be your fastest and safest bet...... Or you can install a sump on your existing tank, run a external fuel pump like a walboro 255 + inline filter to a hose with that has a manual 1/4 turn valve and a push button to activate the fuel pump relay. No real safe way to do it but if I were going to rig something like that up that's how I would do it, hope that helps.

thanks all

I'll get around to it sometime soon.

GM vehicles (at least the 90's ones) have a red wire with a 1/4" female spade connector on them right by the firewall on the drivers side. Connect that wire to the positive battery terminal and it will run the fuel pump even without the key. Not sure if other makes have this feature.

Go to a sporting goods store and get an outboard motor fule line.
The kind with the squeeze bulb in it.
The hose will be small enough to get past the anti-siphoning blocks in the tank fill hose and the bulbwill keep you from needing to **** on the hose to start the siphon.

If you go with the splice into the fuel line idea, just run the engine and then open the valve.
Most of the ones I have seen just use 1/4 plumbing fittings.
The fuel pumps provide way more gas that the engine needs at idle.
That is why there is a return to the tank line.
In fact the return line may be a better place to splice in since it is at a much lower pressure.
