FiTech Fuel Injection User

I have FiTech on my 65 valiant slant6. It's the 4-barrel, the 2-barrel didn't exist yet. I got the 600 power-adder so I could get full access to the data logging and such. That was not an option with the 400. (Though Haven't really played with it yet.).

Their tech support was great. No joke. People told me it sucked. They seemed to have fixed that problem because I called them many times and they gave good advice.

Fuel Pump: the in-line pumps need to be installed lower than the lowest part of the tank, so I went with the in-tank pump option. That was much more work because that tank is not designed for it. After I was done I saw that tanks.com(?) has tanks for my '65 valiant made for the smaller Holley (?) in-tank pump. That might be a better option, but you'd need to mix and match brands. Also, I ran with the regulator on the throttle body and used -6 hose to feed the carb. I used the 5/16 (original fuel line) for the return. It's totally overkill but that's what FiTech recommended. Oh, and the in-tank pump came with a regulator that can be swapped out for a plug (because some of use use the throttle-body regulator instead). But the plug had the wrong size o-rings. It was weird because there are two o-rings and they were both wrong. Easy fix: just had to seal the correct orings from the unused regulator. Not sure why they bother giving you orings for the plug... only to get it wrong.

O2 sensor. The hose clamps they give you are a joke. Weld the bung on and you'll be happier.

Water Temp sensor: You need to drill/tap the existing sensor port on the head. That's a bit tricky. (Or some people have put the sensor elsewhere.)

Linkage: can't say much here because my slant was running a Motorcraft carb before the EFI.

Battery: I had a negative maternal cut-off for my battery. But now, if i use it, I have to let the EFI re-learn. Not a big deal, but worth mentioning. The key info is stored in non-volatile memory. It's only the 'fine-tuning' that gets lost.

I've put <100 miles on it, but it runs and idles like a dream. The only thing I need to figure out (hopefully) is when I'm WOT and the tranny shifts, it momentarily looses some power. It didn't do that with a carb. It used to shift hard and squeek the tires. I want the squeek back.
