I have my Quick Fuels 850 out in the garage, small chamber heads(915's) and a new aluminum intake I will be putting on my current pump gas 440. Its stock bore, and it has 'six pack' TRW pistons.
What should I be doing for fuel delivery to the carb? On the truck already is a Holley Blue pump/regulator and rubber fuel lines. I don't know what size they are. Do I need something special, do I need pump/lines for alky? The carb thats on it already has a fuel log, and a pressure gauge in front of the windshield, so I can keep track of fuel pressure. To date, with pump gas I've never ran it low, a steady 5-6 psi.
FYI, its a street class pulling truck, with a pretty docile cam in it.

So if anything, I should go to a larger diameter fuel line(1/2")? If I were to use parts store "fuel injection" hose, would that be adequate?

If hose is legal then yes you can go to 1/2" but
maybe alum if you want

There is no rules on fuel lines. Just hitches, suspension, drive shaft loops, etc. I just was thinking I was going to have to get a new pump and lines for alky.....This is much simplier solution. Thanks. It has been so long ago since I put this motor together, I don't even remember what the pistons look like. I don't think they stick up far enough, if at all, to cause clearance issues. I'll let you know.  Michael

There was NEVER a POSTIVE FACTORY deck height 6pak piston , 6pak pistons have a 2.061 CH , on a factory deck they are .020ish BELOW the deck at factory 10.725 spec.

Mike , question , why are you switching to E85 ? unless you have cut the bleep out of those 915's you don't really have the compression to warrant the switch ???
just curious
John,
I dont really have the compression (at the moment) to warrant the switch, but did it anyway. My carb was jacked anyway, so the cost of the conversion was not an issue. I can tell that the motor (even at 10.5 comp) does have more mid range torque..and the ET slips seem to verify that.

Thanks , I'm going to put together a fuel system using a fuel cell for my dart .
Are you running pump available E85 or buying barrels ?

I use the pump stuff but I check first to see what the
drop sheets say (to see what the percentage of alky is)
and who has that sheet , the station ?

Yes, when they drop the fuel its in 2 parts, the
alky and regular gas, they will have a sheet that
states how many gal of each then figure the %

Sorry this fell off my radar. I was planning on building a new motor to run on E85. I didn't get it done yet, but have the parts to go ahead and convert it. I have had detonation problems with the junkyard 452's I have on it. The 915's are fresh and I'm hoping for some gain in performance over pump gas. Also, I'm a southern Iowa farmer, my corn the last two years has went to the local Ethanol plant. I'm hoping to do a little more PR work to get more people thinking about Ethonal. Also it would be alot of fun to beat up on trucks running race gas, burning pump gas....
So, right on wrong, that's why I'm going that direction.

As far as fuel drop sheets from the station I get mine they are worthless at best. My first 70 gallons was supposed to be E-70, it was closer to E-90.

When I checked it with the drop sheet it was within 1%
of the actual tested fuel(alcohol tester), that was fuel
from Meijer. I have seen it as high as E-86 in the summer

Raff , do you have your own tester ?
