So what all do you need to run a Dellorto?
I bought a Dellorto with manifold from Ebay. Other than the obvious linkage, what all do you need? Upgraded fuel pump, anything like that? I'm thinking I will do the DLIFDAS along with the carb, so what else do I need?

With any higher flowing carb, its definately recommended to upgrade the fuel pump, and of course the regulator with it. You also need a solution to the OMP rod and lines, either a modified one to attach to the linkage if it doesnt come with one, or to block it off entirely and pre-mix. Not too familiar with the dellorto setups, so not sure if they come with a place to attach the oil lines to.

nice, how much did ya score the Dellorto for? i may be swapping carb setups soon and thats a option.
as stated above get a better pump, holley red and regulator should flow fine for that. is it for a 12a or 13b? either way the holley or carter setup should be enough.

love the braaaap
It is a MUST to upgrade the fuel pump and add in a pressure regulator. The stock pump is very weak in comparison, which is evident in that they fail to flow enough at the first sign of a clogged filter. I would suggest a holley Red pump with an adjustable holley pressure regulator, or get the blue pump that comes with a regulator. I've NEVER heard anything bad about a holley fuel pump or regulator.

On my dell I run a carter fuel pump with a holley FPR dial'd down to roughly 2.25-2.5.
On the omp/mop linkage My rod fit great, and one of my omp/mop lines made it, but I had to cut into the other one to make it long enough.
Oh and a fuel filter right before the FPR. like one of those glass one's or something of that nature.

Was this the one for $425? I was considering purchasing it, but spent the money instead on tires and brakes the car needs to be safe as the holley on it now will suffice.

Those of you with Dellortos, can you guys post some pics or email them to me (the more the better) at boostedfc@hotmail.com?

Good choice choosing a Dellorto! I had mine on an SP 12a and she ran like a dream. Now I have a Weber but a may have to put my Dellorto back on! Nothing much is needed as far as re-jetting especially if its a RB Dellorto. I personally would trade, sell or store the 2 peice intake and get the "longer" one peice intake. It runs MUCH smoother overall. I premix just as a safety precaution but my Dell does have the OMP inlets but I capped them off. Good luck and enjoy your new DELL.
I know many will disagree but this is one of the finest carbs ever made.

yes
do you have the whole Racing Beat filter set up for this carb? i didnt see it in the pics on the auction. i have the kit minus the plate that is attahced to the carb. i see the plate i need attached to your carb. if youre willing to part with it, im very interested in it. also, i have this same carb for my ported 13b. its not running yet, but i have high hopes. also, i may be mistaken but i think i see fittings for your OMP lines in the ebay pics

Depending on the size of the pump's output, the return line may need to be increased. I was going to install a set of SE lines on mine in preperation for a future FI turbo setup, until I discovered that the pump I bought required a 3/8" minimum return line. Pump was overkill.
You will need to replace all of the post pump soft fuel lines with FI rated hose. Replace all of the hose clamps too. Spend the money and buy the solid clamps, not the worm gear ones.
If any of the existing steel lines look questionable due to rust, replace them. It took me a week to trace down a fuel delivery problem that turned out to be a sub-pinhole sized leak on the hardline between the tank and the pump. since that line is on the draw side of the pump, it sucked air instead of squirting fuel.
