Fuel cell location and -AN fittings
2 Attachment(s)
By looking at the pictures was this a good idea?
How do I get the 8 -AN fitting to hook up to my return fuel line? Sorry im not familiar with -AN fittings any help would be great. |
You will need the special fittings to get the proper seal from the cell to anything else. You can get steel ones pretty cheap at a hydraulic shop. I would just run the return into one of you feed ports on the bottom.
The easiest way to think about AN fittings is to think of the number that they are as a fraction with 16 being the bottom number. So, AN-8 ---> 8/16... is 1/2" |

Do you happen to know if your fuel cell was designed to use one of the two sump union fittings as a return, or is there another place for the return? Does one or both of them have a pick-up and/or sock strainer on the inside of the fuel cell? If you are supposed to use one of them for the return, and if both sump fittings are -8 AN, you can use a -6 AN to -8 AN adapter if you want to use a -6 AN return line. Usually it is not such a great idea to have your feed and return next to each other because the return fuel is hot and it is better to dump it where it can cool off a bit before being sucked back into the feed line. If you want to see examples of fuel systems to support a given horsepower level, see the Power Planner section of the Aeromotive catalog. http://www.aeromotiveinc.com/catalog.php

Are you sure this is necessary for your goals?

I already have a Aeromotive regulator with boost sensing.
I would like to make it road race legal. I bought the wrong one for mounting inside. :rolleyes: What tank do you recommend? How does the AN fittings work? Can you just put 3/8 ID hose in it and run it to the hard line? |

I guess I should also point out that most components (regulators, fuel pumps, filters, etc.) tend to use ORB fittings as opposed to AN fittings. Therefore, if you see a threaded hole in the component, it is probably ORB, but if you see a fitting sticking out of a component, it is probably AN. You can save yourself a lot of grief by checking the component's literature BEFORE you order parts.

What tank do you recommend? I like the Fuel Safe Pro Cell with the steel case and optional surge tank. However, you are looking at about $1,500-1,800 for a complete setup, so you may want to consider one of the cheaper models if money is an issue. I guess I should also warn you that the AN fittings, braided hoses, and hard line will cost several hundred dollars.

doesn't the fuel cell need to be completely separated from the interior of the car? Im not sure if what you have there is legal.

In SCCA you will need metal covers for the holes in your floor. The cell isn't legal for SCCA and I doubt NASA would allow it either. Being plastic I would work on some heat shields from the exhaust if you are going to keep it.
Also think about how much the thing will weigh when its full. You may want more than aluminum straps supporting it with bolts loaded in tension. Fuel Safe has a 'sportsman series' cell that is legal in SCCA and runs about $500-600. If you are going to go through the trouble of plumbing the car start with the right cell. |
spent-it: you like the ultra violence as well I see.

I don't think you know what meant when I said how they work. I have the info I needed, 6-AN = 3/8 NPT. The fuel cell has 8 -AN fittings out and I would like to run a 3/8th ID fuel line from ACE hardware to my pump. Can I change the tank fittings 8 -AN to 6 -AN? I have a carb, so it will be low pressure. Should I buy the tank that you have to cut a hole and drop it in? This is what will be on my pump and regulator. 3/8 NPT x 3/8 ID hose. Sorry I didn't explain my set up to begin with. |

Therefore, 3/8" NPT is actually more compatible with -8 AN. You can probably downgrade most of your lines to -6 AN if your engine is not intended to produce more than about 335bhp. However, if you have an external fuel pump, do not make the fuel pump's suction line any smaller than its inlet fitting.
