I'm installing and EFI engine in my '68 Camaro and wanted to try to piece together a decent in-tank fuel pump fuel tank for less than the roughly $1,000 plus they go for from Rick's etc. I wasn't concerned with "bling" and didn't need a narrowed tank, so I could play with the stock fuel tank. My primary concern was baffling, as this is a car that will see a LOT of miles and I need to be able to pretty much drain the gas tank between fuel stops.

I located a local guy (SoCal - and very hard to find someone willing to do the work) who would modify the stock tank as I needed. I purchased a Tanks, Inc. in tank fuel pump kit (probably could have gone with something cheaper) http://www.tanksinc.com/index.cfm/pa...prod/prd84.htm which is capable of about 66 GPH at the 45 lbs/in. my system runs and an Aeromotive tank sump http://store.summitracing.com/partdetail.asp?autofilter=1&part=AEI%2D18650&N=700 +0&autoview=sku. If you look at the larger pciture at the Summit site, the large area on the left is the supply side of the sump, and the inverted "V" on the rights is the return area. The sump is a MUCH heavier gauge material than the tank itself. I also purchased a VDO 0-90 ohm fuel level sender.

We dumped the fuel tray from the Tanks, Inc. fuel pump and installed the pump so it pulled from the supply side of the sump. We capped the extra fittings on the pump, and one of the AN 10 fittings on the sump. I'll use the return AN10 fitting on the sump for the return and plug the other AN10 fitting on the sump. All of the fittings are on the front side of the tank - facing the rear end.

The baffling is outstanding. The sump extends almost to the top of the tank, so once fuel is in the sump, it's not easily sloshed out again. I should be able to run the tank down to 1/2 gallon or so without fuel starvation. The return comes back to the sump in a separate section, so fuel heating in traffic should also be somewhat less of a problem and the relatively large size of the sump should also help keep the fuel cooler. The top is recessed to allow for electrical and fuel connections without interference and the sump doesn't protrude below the rear end.

The total for the tank as it sits is about $900, with $500 of that being labor. Using a factory in-tank fuel pump and lower labor rates than those prevailing in SoCal could get the cost down to $700 or so.

I've attached some pictures and will add a picture in a day or so when the tank's in the car.

How much lower does the new extension go below the stock tank? I wonder how much ground clearance you will have when it is installed.

It's about 1.5" lower than the stock tank. That said, I've pretty much destroyed my mufflers on rocks already, so my previously very lowered car is going to be a little less lowered. As I mentioned, I'll take a few more pictures when the tank's in the car and the car is on the ground with the suspension weighted to show the ground clearance and whether it's protected by the rear end.

I used a rockvalley tank. It worked fine.

I've also heard of people using a mid 90's Impala SS tank as well. Bolts in, no modifications.

I tried to place my 94 Caprice tank in my 68. I would have to cut a hole in the trunk floor for the fuel lines and sender. Going with a Ricks Hot Rod shop EFI tank instead.

Where have you been driving?

Angeles Crest Highway, a mountain road that has frequent small rockslides. At 60mph coming around a turn and seeing the entire road covered with small (and not so small rocks) your options are sometimes limited.

I can tell you there are several mods needed to use the caprice tank. I am going this route and may have done something different if i knew all the work involved with the swap. I am just now finishing up and can post some pics if anyone is interested in how i did it.

Any thoughts on using the Caprice tank in a 69?

[167camaro]

Okay guys, better late than never. I have been busy lately and unable to work on the car, but i did get out there tonight to take some pics of the caprice tank install in my 67. I will be using the caprice pickup assembly with a walbro in tank pump, with the 99 corvette filter/regulator. I replaced the center section that was rusted out on the car originally, and it came out so well it almost broke my heart to cut the hole in the floor for the pickup assembly to clear. But i just couldn't bring myself to pay a grand for a rock valley tank. I got lucky and found a guy willing to cut the hump that covers the pickup on the caprice cars. If you don't have the car to part out then you will either have to find the piece locally or try e-pay, that's where i got mine or fab your own. And for the purist who might be appaled to see the whole cut in the floor, Just let me say in my defence it is not an original ss or rs car. In fact my baby only got 1 option on the trim tag. I believe it was a exterior trim package. Anyway, I used the caprice straps. I had to cut them down about 3 inches in the rear as they were to long. I welded 2 bracket to the trunk floor and drilled a hole in each bracket to mount the straps to the welded brackets. In 1 pic below you will see my finger pointing to an area on the tailpanel. This is to show where you will need to trim a little to clear the 2 parts of the caprice tank that stick out at the rear. Not a lot but just so you know. Clearance between the tank side and the leaf springs is about 1 1/2 inches per side. Haven't got to the exhaust yet but i suspect it will have to exit befor tank. Not sure. Anyway, any questions ask. Want more pics? send me your e-mail address an i will be glad to send some your way. Aaron

What is the last picture all about? Does the tank rub the tailpan?

[167camaro]

The reason the tank needs to go as far to the rear of the car as possible is you need the clearance for the center cover on the rear end. With it installed as i have mine there is about 3 inches. I would measure for you to be sure, but the rear is out of the car getting a posi installed with new gears. This is a huge tank!!
