I'm looking for recommendations for a weekend driver car. i've tried a few fuel pumps, but i believe the lobe is bad on the cam and just want to get her running so i can take it to breakfast, cruise around, nothing special. there are a bunch of different systems out there, so looking for any recommendations of efi carbs to install that are relable and not a pain.

Thanks guys

 

Are you asking about a TBI setups? If so a complete TBI set up (intake manifold, throttle body, ECM, harness, distributor) from a 87 to 95 350 Chevy or GMC truck is what you are looking for. 305 would be okay too but it would need 350 injectors. Best to Google "gm carb to tbi swap". Warning, guys here love to spend your money and going to recommend all big dollar systems ignoring your "take it to breakfast, cruise around, nothing special" request.

 

If it is simply that your fuel pump lobe flattened out, maybe try an electric pump designed for a Carb. There are several available from $50-90. If your carb is still good and tuned well, you should be back on the road for well under $100.

I'd try that first. The factory TBI systems work well, but you'll still need a high pressure pump, some new plumbing and intake manifold. It might end up cheaper than a Brand FT or Brand H EFI in a box kit but it probably won't be any easier.

Just a thought that might save a few bucks. There is nothing wrong with keeping a carburetor.

 

Look at the Holley Sniper system, tank, pump, and throttle body for either spread bore or square bore intake.

 

And it begins

 

i was thinking a efi carb swap, not the intake manifold, just the carb setup, electronics, whetever else is needed. plate off the original feul pump, and rerout the tubes. not loking for performance, just a driver. i know some people here want more power, etc, im looking to drive it for fun now. too old to care about going 150 on the highway anymore. it had its time in the past, now its time to cruise.

missed some of the other responses. something easy, dont really have a lot of garage time now. a couple of days with a buddy, and up and running again. sad to see her sitting in the garage and not being used a bit. i figured an efi carb and the electronics would be the easiest. i looked into an elctronic feul pump, but then went down the rabbit hole of shut off valves and other things. I have no idea about the carb on it, aside from its an hollley that mey have to be rebuilt as well. jus know no fuel is getting to it.

 

How do you expect EFI to work without a high pressure pump?
Also, have you disconnected the fuel line from tank to carburetor and blown it out with air?
Have you removed the tank pickup and checked if the sock on the pickup isnt blocking fuel flow?

First, visit the website for a company down in Florida called Efisystempro.com and then call them and tell them what you have and what you want in the end. You keep referring to a EFI Carb swap and that is a bit confusing. The system I have on my 1968 C3 is a Holley Stealth Sniper which is a throttle body that comes with four injectors built in and can easily handle up to 650 hp. There is more to it than just swapping the throttle body for the carburetor. The Holley Sniper and Stealth Sniper have their controllers built into the throttle body. I had to add a Coolant Temperature Sensor and an Oxygen sensor as well as run the power wires to the fuel pump and system power wires to the battery directly.

The Fuel Module I bought allowed me to pull the original float sending unit and replacing it with a new Float Level Sensor along with a new Walbro fuel pump and a pre-set 60 psi fuel pressure regulator. This device saved me from having to spend a lot of money on a new fuel tank and parts separately I had the whole fuel system wired and connected in in less than 1.2 hour. Holley even includes a piece of their amazing "Hydra Mat" which replaces the sock on the fuel pump. On my setup I did not need to run a "Return" line from the tank.

I had a budget of $2500 and ended up with over $600 in change by the time I started the engine up. If you take your time and follow the instructions for the EFI system from Holley you can do it all yourself. If you go to their website they will even make a list of parts you will need just for your Corvette.

The Holley systems are pretty amazing and they offer some awesome features to customize it to your Corvette. Take a look at the Holley EFI Software when you get a chance. I bought the Terminator model because it looks just like a carburetor where the plain Sniper is turned 90*. Edelbrock also makes some incredible hardware and they offer multi-point EFI like the modern cars do. It requires that you replace the intake manifold. There is a lot of information out there regarding both brands I have mentioned. The reason I bought the system I have from Efisystempro was because they offer 24 months of technical supoport from a Holley Tier Three expert that works at their shop. When I bought my system he called me and gave me the best ways to contact him as well as some valuable pointers for before you start. 2 years of Tech Support from the gentleman at efisystempro was the big decider for me, I am an engineer and familiar with EFI but I wanted to know I had help when I needed it. Holley has good tech support from the factory but the support you get from efisystempro blows it out of the water.

I wish you the very best in your search for a replacement to carburetors.

 

You are looking at a bunch more aggravation, work, homework and expense tryna swap to efi. First find out if fuel pump cam goes in-out. If not, the electric fuel pump is just one of the zillion things you gotta do to go efi. Carb is already there. No converting. Just fix it.

 

I don't think we have established that gasoline is even making it to the pump.

 

Well, since we are at the point of suggesting a Holley Sniper EFI system to fix a fuel issue, I'll point out that you may be able to find a complete LS motor for less.

You'll still have to do the other stuff that you would have for Sniper EFI, but you'll get multi-port injection EFI, coil-on-plug ignition, an intake manifold with no coolant or exhaust passages, and you'll delete the mechanical fuel pump cam.

Perhaps an electric fuel pump at carb pressure would solve your problem?

 

and any efi requires a new fuel line from tank to carb. 2 actually. that 50 year old steel line has been vibrating, corroding and being hit by rocks for half a century. and it is designed to pass fuel at less than 0 psi. it is sucked thru line by fuel pump at engine. when it fails you lose fuel to the engine. car stops running. if that same line fails with 60 psi in it, you still get fuel to the engine. car keeps running. while you are spraying fuel all over the underside of the car.
