Hi,
New here, and I'm about to purchase a 30003 unit. (I believe this should be the right unit for me.) I've got a 66 Mustang, 289, mild cam. I'm not looking to squeeze every last hp out of it, but just have a nice driver that doesn't stink of gas. Right now, I've got a Eddy performer 289 intake and Eddy 1406 carb on her. So now for the list of questions:
1) Holley makes an in tank fuel pump that does not require a return line. Can I just dead head the return port on the TB?
2) I've already got an electric fan, and I installed a temp sensor in the water outlet. Will this location be suitable for the Fitech coolant temp sensor?
3) I've read and heard the rumors that TBFI units do not like dual plane intakes. Is this something I should worry about? Is anyone else using a Performer intake?
4) Do you think the 5/16" steel line will suffice for the fuel line? I'm only at about 200hp.
I put fitech on wife's '71 vette with performer rpm manifold, and it works fine.
I run mine on a Weiand Stealth, much like a performer. You can't fit much more intake in your car without a different hood. The Fitech will work fine.
I would suggest you look at the 30002 or 30001 units. These have timing control where the 30003 does not. The added timing control can aid in fuel mileage and driveability.
EFI will not increase power over a properly tuned carb. What it will give you is reliability, repeatability and economy when setup correctly. You may still experience some fuel smell in your garage, but that is usually from the tank venting off pressure. Not the carb or fitech.
Another huge advantage with EFI is the adaptation to changes in altitude. I took the wife's '71 vette up to Kit Peak and it ran great. You wouldn't get that with a carb.
Thanks for the replies. I'm not looking for any more HP, so that is not a concern, but really just the reliability of FI. Is anyone dead-heading the return line, or is that just a no-no?

I do not recommend a deadhead fuel system on the throttle body units. Too much heat in the unit for that fuel to be sitting there. Some have done it with the Corvette LS return filter. Have not seen their results, but I cannot imagine their performance is as good.
I know it is a pain to run a return line, but....
