Fitech swap on my 1972 K20

[snj8198]

Hi coopdog, First, very nice truck you have! What intake are you using with the new efi system? During your research into FITech did find any prevalent info supporting using either a single or dual plane intake manifold?

I'm running an Eddy Air Gap currently with carb but I'm considering switching to the FITech but I keep getting mixed info on intake preference. Any insight would be appreciated.

Thanks

Steve

Cody from FITECH told me that their system works with both duel and single plane(of course they said that) but he told me that the single plane or a duel plane with an open riser/spacer work the best. If you are running a duel plane he said that the base of the TB has an X pattern notch in it. Since I had the duel plane I just added a 1" spacer that was open, Actually it is an adapter plate from the spread bore to the 4150 flange.
My TB is still on back order so I installed a Holley until the TB comes in.

Interesting, thanks. I too seen on FItech's website that either intake is fine with their system but I'm concerned that the divided plenum of the dual plane would hamper fuel atomization of the spray so I have been researching whether a small open plenum single plane manifold would be better for spray distribution. Perhaps like a Victor Jr?

The reason I asked the question is I seen on the you tube video of engine master(the Roadkill guy) had problem with the FI with a duel plane so they went to single plane and it worked well.

I found the episodeEngine masters Episode 2

Getting ready to start installing fi tech setup. Man I hope this thing is worth the money !!!

Great looking truck - that sure likes a great fuel injection system!!

[coopdog]

Radical man, you will be nothing but impressed with the kit. I took the truck for a ride just the other day, and man does it run good. just turn key and go. I must say though , some fine tuning will be needed to get the system just perfect. but still the kit makes a world of difference.

[Birdman72]

We'll finally fired up truck tonight, started right up on first try , had a rough idle had to keep foot on gas pedal , finally leveled out. Ran for maybe 3 min then started pouring fuel out of vent on command center. Have a holly performance fuel pump by command center gauge was 7psi supply.Rechecked fuel supply in and out all is plumbed right. Gonna give fi tech a call !!

[Birdman72]

Can't get in touch with fi tech support. Tried all day left messages nothing in return yet. Read on there Facebook page people been trying to get in touch for a week and no return calls. This is just my luck

any luck today Bird?

[Birdman72]

No sir. Tried for two days left messages to call back. Hearing from lots of people that the customer service is bad.Did get one email reply that said vent needed to be ran back to tank. I should save up for an efi tank if I have to run a hose all the way to my tank.

[snj8198]

I have been reading on the Chevelle forums about your exact problem with the Command Center. Most say save the $400 and put it towards a proper tank and fuel system. Look around their section, there is a lot of FITech chatter there. There is a lot of knowledgeable hotrods there that have gotten their feet wet on the FITech system and are sharing their what they have learned.

Thanks for that info. I finally got in touch with them today,they said sounds like needle and seat are stuck. They want me to remove low press fuel quage and check it. We will c what happens.

We'll pulled needle and seat could see no visible trash, put back in and same thing. Got back in touch with fi tech supposed to call me Tommorrow . I sure hope they can get this resolved cause my 670 holley sure was running good. Would hate to have to put carb back on but I c where they are having a lot of issues with FCC and some fi units.

[First c10]

Could the float be out of adjustment? Or just won't close?

[Birdman72]

That's what I hope it is. Maybe they will give me some good info but I have it boxed up ready to ship back Tomorrow just in case.Man I am kinda scared of the FCC know worried about longevity if unit. I understand that you can have problems with any set up though.Got a truck show in 2 weeks that is 2 hrs away was hoping to have fi system ready by then

[Birdman72]

We'll got FCC boxed up and sent back today. Hopefully they will get me fixed up soon . I am ready to finally c what all the hype is about. They also said they are getting a lot of FCC in to ship the next week.

[First c10]

I hope they get you straightened up fast. I'm still waiting on my throttle body I've had my FCC for a few weeks

[Birdman72]

Me to I will keep it updated.

[y5mgisi]

I don't understand why there needs to be a needle and seat setup in there. Why can't the mechanical pump just pump it full?

[First c10]

If not then the fcc would not stay full. Then it would also become a pressure vessel and I am not sure it is designed to live in 7-9 psi. Hope this makes sense

[coopdog]

So fellas how's the trucks going? I got this shot the other day, makes Monday mornings a hole lot better

[snj8198]

tease!

[Birdman72]

Coopdog what size air cleaner you have on your truck. Is it touching your firewall ?
