Hello, so I need a bit of help figuring out how I can drain my fuel tank in my vehicle without completely dropping the tank itself. I am in the middle of an engine swap on my 97 Monte Carlo LS and I’m currently waiting on the arrival of a cherry picker but in the meantime I wanted to empty my tank and put the fuel in my brother’s 01 Monte Carlo SS since the new engine (L67) requires 91 octane. Plus also I am using his vehicle as my daily since he is not old enough to drive without an adult over 21 and I figured I could save myself some money if I take the gas from my car. I have tried using liquid syphons but the tank is too far away from the filler neck’s opening for me to get anything out. I have also tried draining it from the fuel line by removing the fuel filter but that thing will not budge an inch. I really don’t want to drop the fuel tank just to get 10 gallons of fuel. Anyone know how I could do this?

Thats what I used, the hoses are over 4 feet long. If you needed more for whatever reason, you could always chop some off the outlet and couple it to the inlet too.

One thing to note, my stock fill neck on my 96 had some kind of trapped ball thing partway down the fill neck that made it impossible to get a hose past. The aftermarket neck I bought (stock one was heavily rusted and broke when I dropped my tank the first time) was just a normal open fill neck.

TBH it sounds like more hassle than its worth. Youll easily burn up that half tank test driving the engine swap and getting everything burped and verified. Not like you're going to drop it in and go do burnouts immediately after anyways.

IMO if you had to do it, I'd figure out how to get that fuel filter off. You need to be able to operate that to replace it regularly anyways, so nows as good a time as any to fix that issue.

 

Thank you, I’ll be ordering that and I’ll see if I don’t have that weird ball, if I do, I’ll just throw in octane booster and use whatever’s left in my tank to help diagnose any issues
