Mods, if this is in the wrong forum... My apologies...

Legitimate question here though...

I have a '94 Civic, into which I pumped $26 in gas on Sunday, totally not remembering that I was picking up the new Accord on Tuesday..

Anyways... I have a length of vinyl tubing, with an id of about .5 inches, od of maybe .75 inches... So I think I'm gonna be slick and siphon out all but about a gallon of gas from the Civic, as not to waste my money, but ran into a problem... The tube goes in about 2 1/2 feet (maybe less), then stops, so I assume I'm at the bottom of the tank, but I'm not able to get anything out... I've got a fish tank siphon starter (with a hand bellows) but it just sucks air...

Any ideas? Maybe I could pull the back seat and then the fuel pump, and siphon it out that way?

Bump?

At the bottom of the filler neck there is a small filter/wire mesh, specifically placed there to prevent syphoning. Most vehicles on the road today have one of these.

Well that friggin blows...

Can I take out the pump assembly and get the gas out that way???

B18C_EJ8

Anyone?

Look how the fuel pump flange isn't up on the highest part of the tank... If you unbolt that when the tank is full, you'll get a couple gallons gushing out suddenly.

The bottom of the tank has a drain, but I don't know how you'll keep the gas clean if you use that.

Maybe disconnect the return hose from the fuel rail, connect a hose & put it into a container. Then jumper the fuel pump to run, & pump it out.

JimBlake, you rule. :thumbsup:

I was thinking the exact same thing about the fuel line into a container... Just not sure how to jump the fuel pump so it runs all the time...

there is a 17mm bolt on bottom of gas tank you can take off and put the gas into a container.....

much better than syphoning....

or just take 17 mm bolt off the fuel filter.... and keep turning car on and off....

B18C_EJ8

I thought about the turning it on and off thing, but how much is going to come out each time the pump primes? I wouldn't think it's alot, so that could take forever...

Gotta figure out how to jump the fuel pump to keep it on all the time...

Anybody got a scan of the wiring drawing for the fuel supply system?

If you use the return hose, take the hose off the FPR & plug the hose. Then take another long hose, stick it onto the FPR, & put the end into your container. Or into your other car's gas tank.

I had a problem with my main relay and wired in a toggle switch. It doesent
have the 4 second prime any more( it runs constantly) but I can shut it off as well.

If you remove fuel line at the filter then remove your main relay, you can put a jumper there then switch ing on. It will keep running untill the fuel is empty.

Without a wiring drawing, here's my guess...
Go back to the fuel pump, note the wire colors. Go to the main relay, find one wire the same color. That's one side of the jumper.

I think Honda uses black/yellow for a hot wire, or use a DMM to find one with battery voltage. Jumper those 2 together.

That's exactly what's going through my mind too... Too much work for 10 gallons of gas .

Stop being a cheapass, fork out another $20 for gas in the new car....damn, with G dubbaya as president, twenty bucks should be potatoes for everybody. . . .


17mm drain plug at bottom of tank, get a big sponge and stick it on top of a bucket with an opening the same size as the sponge, drain gas onto sponge so that it filters into the bucket.

Sorry if I'm not independently wealthy like you seem to be... Around here, that 10 gallons of gas is like $27... And for a half hour of work, that's worth it to me...

HeikDiesel

youve already spent more than a half hour online trying to figure out how to get it out. IMO not worth it.
