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 (http://www.tanksinc.com/index.cfm/page/ptype=product/product_id=84/category_id=61/home_id=61/mode=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 (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.
