EFI Fuel Tank
Wanted to get your thoughts on the following products. I'm in the middle of planning my fuel system and until I found this site, I wasn't too fond what's available in an acceptable price range for EFI. I will either go with FAST, Powerjection or Carb on a RPM manifold.
The site is: www.tanksinc.com
Check products / fuel pumps - he offers a depth adjustable, baffled walbro pump fixture that is plummed and wired. Looks like you cut-out a template in the top of a factory tank, and install with gaskets and fastners. The cap/seal the original return line and use the original sender. He offers replacement tanks for older vettes too.
Thoughts?

EH, just run a frame mounted pump for <100 bux from a parts house....been that way on my '72 for some 15 years now....tank-filter-pump-stock steel line to injection-regulator up front-stock steel line to return on top of tank....
only slight problem is the 18 gallon tank is now 16 gallon, on account of taking hard right turns, runs the pickup dry, engine stumbles....I have not yet gone crazy over it yet, maybe next year, maybe not...only been 15 years, why start now???

My car is a '68. From those familiar with modern in-tank assemblies, will this configuration perform on par with your typical late-model factory efi delivery system. I like the fact that it should be quiet, prevent cavitation to the feed, and support my hp needs. I'm purchasing a completely new fuel delivery system anyway. My big question is on proper design. Thoughts?

The late Sharks have a Tank that has a Fuel bladder inside wich makes it a safer tank. They also have a larger opening where the fuel cap assembly bolts to the tank. It is large enough that You can fit an in tank pump just like Gm did to the 82 without cutting the Tank at all. The 78-82 Bubble Window cars Tanks will not fit the earlier Cars. I have been told that the 77 Tank also has a bladder and has the Larger opening wich would fit Your car but I have never seen one in person and can't be sure. I used a Bosch pump and copied the 82 way of doing it and it works much better than the buzzing external pump I had before.

Here is another option for you. Check this link to see the parts needed to install a F Body intank fuel sender to your early model fuel tank. This type of setup is returnless meaning you only need to run a single fuel line to the fuel injected engine. http://www.vetteworksonline.com/cata...roducts_id=178

The 82 pump isn't all that great. It was intended for a Low Pressure TB system and 82's even run better with a later or better pump. Besides the Early tanks are Flater on the Top and the Late Tanks are Angled so the 82 won't fit right. I tried to mod the 82 setup to hold a better pump but its all made of pot metal and it can't be welded. I just used the 82 setup for design and made my own system out of Stainless. Basicly there is a round plate that bolts to the top of the tank in the stock holes and then a tripod of 1/4' roundbar that looks like an up side down Teepee that holds the pump. Then a 1/2' line up from the pump to the plate. The Stock fuel Sender is attached to it as well. A local hotrod shop had a billet Fuel cap with a Stainless Nipple that is welded to the top of the plate. If your Tank is in good shape You may want to cut a new hole like to camaro pump above. If your Tank is not in good shape then You may want a newer one the way I did it. There are also complete custom Tanks avalable with the pump all ready in it.

Gale, thanks for the tip.
Ken, I think the '98-'02 LS1 sump assembly from vetteworks looks like a great deal. I'll give them a call. I wonder how the depth of that assembly will work with a stock '68 tank.
All, thanks for the replies. I still need to drop my tank and check its condition. Not a big deal if I need to buy a replacement though, but from what I've seen, I'm going to use a factory type tank. I want it to fit properly, and I don't want to pay for the custom stainless in-tank EFI set-ups. I've got an SRIII frame waiting on a fuel delivery system so its the perfect time to plum one up.
Here's my dilemma. The frame was designed for side exhaust because that's what I've wanted all along. I really want the Hooker side-pipes, and I've already purchased them. I've since read that a lot of folks have had a lot of trouble with O2 sensors operating properly because of the distance to the collectors. Too many variables on the forum though. Don't know if this was only a problem with early system "one wire sensors" or if it will also be the case with today's components. If I go EFI, I will either go with FAST, Powerjection III on a RPM Air Gap or Holley's Stealth Ram. I really like the HSR.
