Has anybody here modified their original tank (pre-75 cars) to mount an EFI pump internally? Anybody got tips or pics?

I need to do the same and was looking at Tanks Inc. setup. You can see it here: Tanks Inc. EFI Fuel Pump I found this guy that installed one: Camaro EFI

Thanks guys.
I'm really having a hard time deciding whether to go in tank or rail mounted. Servicing would be easier on an external setup but internal would be quieter.

I went through the same issue trying to decide what to use on my challenger. I ended up using the competition engineering sump welded to the stock tank with a external pump. It has worked pretty well, but you do hear it when you turn the key on. After the car has fired though on mine you can't hear it over the exhaust. Mounting to the rail with good rubber bushings helped alot.
Here is a link to a video someone took of my car where you can hear what the external sounds like.

Dragula, what exactly am I seeing there? Did you build a fuel cell and drop through the trunk or what? It looks nice but I'm definately confused.

There was a car in one of the mags a few years back, a duster called "dust ya" he used a stock tank, but modified a stock sender to mount an efi pump
here is a pic. I believe he used a corvette fuel pump.
That's a lot of extra weight to place on a soddered-in stock fuel pickup tube. I would at the least weld up a bracket for the pump going from the pump to the mounting area of the pickup. After seeing an 80's 2.2 carb fuel pickup and an 80's 2.2 turbo fuel pickup I can tell you that's about the only functional difference between the two.
However that raises the issue of a sump. Going through the trouble of rigging up an in-tank efi fuel pump doesn't make much sense if you don't have an in-tank sump to go along with it.

Yes, its sunk, and custom, my design. No 90* bends to heat the fuel, no cheapish stock stuff, and the pump bracket actually handles 2-A1000 pumps.

Wow, that is trick! That gives me some ideas. Oh if I only knew how to run a TIG.

Check out this shop. Nice folks to talk to on the phone, and they do custom stuff if you don't see what you want there. http://www.rickshotrodshop.com/I'm going to have them do the Aeromotive 1000 pump with a pair of #10 lines out/return, and have my stock size tank expanded 1 inch down and a few inches wider on each side. Not sure how much exactly until I fit the 3" TTI tips on the 1970 'Cuda. I'm hoping for 5 more gallons of fuel capacity.

Check out xvmotorsports.com
they have fuel tanks for B and E bodies set up for EFI conversions. The price is similar to the one price I saw on ricks hot rod site.

Thanks for the links guys.  Unfortunately mine will have to be custom as it is going in to my '65 Sport Fury. People just don't seem to offer much for us C-body guys.

I would not use them. The pics of the stuff they used to have on there showed a lack of understanding on some of the principles of efi and their prices were very high I thought.
Although, they are one of the few companies that do them, if you use them, stay away from any re-used stock fuel pumps like they still show in the pics and all 90* bends in the fuel system. Also, I would go aluminum as I did on the fuel cell. No need for stainless. Mine ran me about $400 plus the pump and filter, which I already had. Off the shelf fuel cells don't work very well either for efi. They can be made to work, but not nearly as well as a custom one.
There is more to them than meets the eye, and I incorporated a few tricks into mine to keep the 5/8" pick-up in the fuel at all times... It fits my Cuda with full wheel tubs, leaf springs, roll cage, and wheelie bars....exhaust is out under the doors.

Rock ValleyOn a semi-related note, does anyone have a resource for the LARGE o-rings used to seal some of these pumps? I've got a 2000 Z-28 pump with integral swirl pot that I want to use in my A-body tank, and I need a thicker o-ring to seal the pump to the tank. The 2000 Z-28's used a plastic tank and the lock ring setup can't be swapped in to anything else. I pirated the top of a different GM tank to do something similar to what gdemon did, but the pump fits a little loose in the new top. I kinda don't like a little loose anything in the fuel system, so info or leads to the proper o-rings would be greatly appreciated... I'm sure the same setup could be used on the C-barge tank, with a little fab work. Clair

The earlier F bodies (LT-1 powered, pre '98) used a steel tank, so that might be an option next time around. For the O ring, did you just try and GM dealer? Give Eric (the mod) a PM and bet he can help you out
Using the entire F body fuel tank might even be an easy way to go  
I am going LS1 in my old Torana..and I have a sheet aluminum fuel tank for it (repo of the original Bathurst race, long-range style ones) and thinking I will probably go inline pump with it...just working on the engine bay side of the swap now..will get to the fuel system once I get the engine in

I actually looked at using the tank from the 2000 - I bought it because it's strangely close to the shape of an A-body tank, except for no kickout in the tank for the spare tire well. My measurements indicated that it would fit length, width, and depth-wise in an A-body if you turned it around 180* from the F-bod orientation, so it was worth a shot. I ended up ditching the project because the fuel filler tube was now on the wrong side for an A-body, and I didn't want to relocate the filler cap OR have huge runs of large DIA fuel hose inside the trunk of the car.
The 99-down F-bods don't use the same neat swirl pot design which is what I really want to keep out of that experiment. Push comes to shove, I suppose I could sort out a way of butchering the top of the pump to adapt a 99-down top and lock ring, but the point of all this was to be able to stop in to a parts store out in BFE Nevada and ask the counter monkey for fuel pump they might actually have.
I'll have to give Eric a shout, as I don't know this GM stuff very well. Is that his username as well?

Yep, Eric for name, all around  I got to know abit about the later F bodies after building This and having had a bunch of other ones in the past. (Just built another 2000 model one in Oz that is on it's way here) On the fuel filler issue with the plastic tank (turned around 180 that is) you could always move the filler on the car to the other quarter panel  I am looking around now for a wrecked 2000+ one with a 6 speed for the Torana, I can get some pics and measurements if you like of the tank, pump assembly,etc when I get to it.

Go here... http://www.oringswest.com/ And read about O rings, they can provide the diameter & cross section you need in various materials & have a compatablity chart that will tell you whats the best choice...

No. Never spent the money for that unit. Nice idea, but a vaccuum referenced regulator already reduces pressure some when your not on the throttle. Also, I didn't want to retune the fuel map either.

Have you had any vapor lock problems? They recommend for a street driven car that you use the controller but I don't want to drop another $300 for a freakin controller.

I have had what could be considered a vapor lock.....When I used the existing fuel cell, the foam was cloging the filter, and the pump managed to pull it thru, and the AN08 vent was not nerly enough, and I imploded it! Does that count? But no, you don't need the controller, its a nice want to have.

I have a tank from a 2004 Silverado too that I am not too attached too it has the sending unit and all still as well. (is basically like new, was from a truck I parted out when it was near new) it is plastic as well..could chop it up in the name of science though...might have the same diameter sending unit assembly as the F body?  
Oz,
The plastic tanks are nice pieces, but only if you can use them as-is. They don't part out well because the plastic is REALLY thick, like over 1/4" in 2 layers of stuff. White on the inside, black on the outside. The lock ring setup for the pump is molded in to the plastic, and the plastic itself forms part of the sealing surface so you can't really cut/past parts. That's where the quest for the right o-ring begins...

I hear you...just thought I would mention it, since kinda tired of looking at the tank sitting along side the garage One nice thing about the '69 Camaro I did, it has the late model floor pan, so the 2000 model fuel tank bolts right in and all the factory lines click onto it. And going with an inline fuel pump on the Torana should be pretty well straight foward I am thinking.

I really like that Rock Valley setup! However, I decided to try it on my own and went with the Tanks Inc PA4 pump and baffle setup for my 56 Dodge after researching it as much as I could. Here is a link to a setup in a Chevelle. http://www.thedetailzone.com/Tanks%20Fuel%20Pump%20Install.htm.My tank is shallow so I dont have the depth to recess the top and will have to beat some room for the fuel lines up into the trunk. After all the hours I spent heating and working the floor to make room for the T56 Magnum 6 speed, making room for a fuel line should be a piece of cake. I cut the hole where the pickup would be at the lowest part of the tank and right where the OEM pickup was. I did not realize the vent tube was right where I was drilling but its not a problem it will be removed and plugged along with the fuel pickup line. The tank is not flat so had to hammer out the ridges. After some hammering and heating and shrinking the metal I managed to make it pretty flat. Its not done yet but so far it looks like it will work out just fine.
