Anyone have any information on putting a fuel cell in the trunk and what fuel pump to use ?

It's all going to depend on your local track rules. Some are very specific about where they want your cell placed. The earlier cars have external pumps..that all you need.

Some using fuel cells with fuel-injected cars have recommended using the small "black box" style surge tank (inside the cell) to ensure adequate fuel flow under all conditions.

Here are the rules regarding the fuel cell. So my 1980 has an external fuel pump? What size hose should I use? Is it possible to make it run with out the seperate surge tank?

1. Stock fuel tank mounted in front of rear axle may remain in place. Rear hoop required if stock fuel
tank extends above centerline of rear axle. Hoop must be a minimum of 1 1/2” x .065 tubing. (See
tech. director for specific mounting details.) All other tanks must be replaced with a boat tank or fuel
cell, 8 gallon maximum.

2. Tank/fuel cell must be completely covered, secured, and located in forward most part of trunk or in
rear part of passenger area. Approved racing fuel cells exempt from being covered.

3. All fuel lines must be under car, (may not enter driver's compartment), and protected from being cut.

4. No glass of plastic fuel filters allowed.

see John Mock's write up on fuel cell placement , can use ford ranger fuel pump in tank ;works great , surge tank is needed get fuel cell from air cooled racing sells atl cellsi . he is in Pa and will give you the very best price of anywhere. Tell him I sent you! Get plastic surge tank from fuel safe cheper than atl . You can fit 10 gal tank in rear of car under floor and passanger side did one in 924s worked great really safer with surge tank ! You want starve for gas in a high speed turn ! Truth factory tank location is probably the best but fuel cell in shape of factory tank will be 2200 bucks or more atl box shaped cell wil be 3 to 4 hundrd jesse ps need any help email me or call will be glad to talk you through it.

search this board , you will find it under fuel cell or John Mock , I believe Vaughn posted it from John's site he is director of south east division of 44 cup you can do it Johns way and use stock fill cap but cost a little more for the back flow preventer , or you can use standard cap and make trap door infloor of car to fill , afterlifting hatch cover , thant way tank is seperated from rest of car Jesse
