Anyone here installed the FiTech fuel injection system? If so what are your thoughts on difficulty of installation and how did you do the fuel pump, in line or in tank?

I have wondered if anyone on here has installed one also. I was thinking the FITech  fuel command center would be the easiest way to add high pressure fuel.

What are the advantages of FITech over the Holley Sniper EFI?

Someone here DID do the FITech, or maybe it was the modified forum, but he was having some difficulty with the system and customer service with helping him work the bugs out.

I have it installed, i currently have the stock fuel tank and modified the intake line and plumping the fuel pump under the car is not difficult just that with air ride installed there is only certain areas it can be put and it is about max 3' distance from the tank and does sit lower.  I am waiting on a new fuel injection fuel tank from Tanks. Inc it is made for a 65 impala due to the reason they don't make cadillac tanks and will see if that fits. They have a intank pump that goes with it so it will eliminate the fitech fuel pump mounted under the car. The fitech its self run great on the car once it is up and running, really brings out the low end power of the car from dead stop and as far as fuel millage i can't say anything yet i hope it will increase. I have been working on and off with it to get the bugs out i have had issues with it not wanting to start up right away even after the motor is warm.

Not trying to hijack this EFI thread, but I've been looking for an EFI-ready fuel tank and am experiencing the usual problems finding a replacement 26 gal Cadillac tank.

Re:  the Impala tank.  The website description pics imply a 37" width for this tank.  Stock tank is about 32" wide.  The 24 gal Impala tank should fit but what are you doing for exhaust?  Will there be enough room for dual exhausts?

The efi impala tank does fit but with the air ride and going all the way down to the frame i it hangs close to the ground lil to close and the stock straps will work but i plan on modifying them.   You could just by the efi tank pump and sending unit and just cut your original tank for the pump and use the old hole for the sending unit. little custom work but will save 260 for a tank that doesn't fit exactly right. the filler neck on the impala tank suck up tighter to the body.

Thanks for the impal tank info!!

I’ve got a mimic bosche 44 in-line mounted near/below the rr seat area. It is about 10% as loud as my suspension compressor so I don’t foresee any future issues with it. I’m also using nifty AN fittings with braided hose after the pump feed.

Just curious why not use the fuel command center instead of a new gas tank and in tank or in line pump? Plus it is completely reversible back to stock.

Yes that’s a beast! Inline pumps are just as easy to revert.


One day maybe....:-)

after reading about this on the 63-64 caddy forum it seems like doing a LS swap is not a hole hell of a lot more work . 

on the 63-53 caddy websites a guy did the FItech with theyre fuel command center did a huge rite up on tunning and all that. 

one thing to remember is that you whole system {motor, fuel , exhaust ) everything need to be tight and no leaks or any vacuum leaks. he was having issues because he had exhaust leaks and the O2 sensor was reading invalid air/fuel mixtures throwing everything off.

i think people no days want to slap something on in hours and have it run like a brand new car. doesnt really work like that . lots of testing ands trial and error.

What you are saying is correct about feeding the ecu good data for good algos....but...
I own an LS swapped car and a fuel injected Caddy with a decrepit y-pipe. One was easier by lightyears:-)
