had a detonation issue (66 Hemi engine - stock - rebuilt - 10.25:1 compression) - spoke to builder (who rebuilt the engine for the previous owner) who told me the engine likes about 5g per tank of racing fuel (leaded) to make it happy OK so looking at options buying a 55g drum is most economical - that leaves me with having an "open" drum of gas in the home garage - when i say open, it would be a small round opening (2-3" in diameter) with a hand pump screwed into it - idea being i pump 5g into a small sealed can and leave in back of car for the next fill up each time (gas in trunk is next question) - how dangerous would this be to have at home? - i would imagine that the pump has a gasket where it screws in to the drum and an internal seal so that fumes don't just continually seep out - but still? should i then be afraid to do anything with a spark (i don't weld (although i have a cheap HF welder i have never used - but could one day) but have plumbed the compressor using a butane torch - would this now be out)? the alternative, although more expensive, is to buy 10 or so 5g pails - each one would be completely sealed and when opened, used in its entirety and what about the idea of driving around with a 5g jug (or sealed pail) in the trunk? - would you guys have a concern about doing that? thx!

This is a homemade air dispenser, you screw in the dispenser pipe/hose and shut off valve into the 2" opening. They you install the air fitting into the 3/4" opening. Then I open the valve on the discharge pipe and put the clear hose into my fuel jug. Then I carefully crack open the ball valve for the air and bleed 5-10# of air pressure into the drum. The fuel goes up the suction/discharge pipe and out into my fuel jugs with the drum standing up. Never apply more than 3-5 psi in a drum, anymore than that can cause the drum to rupture. I shutoff the air first before the jug get's full and then close the other ball valve when the jug is full. I can fill 10 or 11 jugs the whole drum in about 5 minutes or so without spilling one drop. I always emptied the drum each time I did it as we could use 50 gals of methanol in a weekend easy. We never hauled drum of race fuel in our race trailer, that is a bad idea. This method could also be used to fill a car up, up hill from the drum with a longer discharge hose. Clear discharge hose allows me to see what I'm doing better. But with gasoline you should used a gas hose with a steel braid inside so the drum is grounded to whatever your filling with gasoline unless your filling plastic fuel jugs then it does not matter. I have it setup now with a quick disconnect for my shop air and I empty the drum all at once. There was a time where I used nitrogen to push the fuel out, and left methanol in the drum, but that got expensive when the nitrogen leaked. So I have been using shop air for 20 years now. FYI I used balls valves here because they open and close fast and if they leak a little it's not while I'm not there.

Yes a valve like that, it seals good and won't wear out like a ball valve will, screw a street 90 into it along with a short nipple to screw into your drum. Crack open the 2" bung to vent the drum while your dispensing. Also a gate valve is much less likely to be bumped open like a ball valve could.
In a corner away from your work area I would not have problem keeping it in a attached garage.
But if there are any ignition sources nearby like a water heater, NO WAY!! would I keep it inside in case the drum leaked and they do sometimes at the seams.

Not what you asked I know... but do you really need race gas for 'only' 10.25:1? 12:1+ I would expect to need it. What are the motors specs?
If you ever find yourself in a fair fight, your tactics suck.

Fuel in a drum is probably safer than fuel in most automotive gas tanks, so I stored it in a corner near a door.
good point...i hadn't thought of it, but of course the car's gas tank is a can of fuel in the garage too - and the gas cap on the car is no better than the bung at sealing the tank....

here is another link on Tony http://www.pro-system.com/assaultshow.htmlreally nice guy - he is strictly a hemi engine rebuilder - that's his living in fact, Arias piston had him design the street hemi piston they sell - the guy he worked with is now on his own...i'l track his name down

I've built and blueprinted severakl 426 Street hemi and street and strip hemi as well as several blown street Hmei. It would be nice to know if he figured out the actual true mechanical compression ratio and if he checked the CC on all eight combustion chambers while checking the compression ratio(including pouring each cylinder with the piston dome down below the deck to determine the true dome volume on the pistons), I've seen 4 CC varience on the chambers on one head Several different things can contribute to detonation, regadless of the fuel used and the compression ratio, spark plug heat range, ignition timing, sharp edges in the combustion chambers,(valve edges ) especially on the exhaust valves, the ambient outside airtemperatuures, humidity, the barometric pressure, the actual altitude and the air density outside that day I'm suprised that your having detonation issues with your motor, is there any chance that you got some bad pump gas or had some old bad fuel in the tank to start with? BTW, the first NHRA legal 426 Street Hemi stocker motor I built and race by myself ran under the existing NHRA A/S record on the third run at the 1975 NHRA Winternationals If you check my past posts you will see me commonly referr to those motors as 426 Hemiriods
