Any racers have FuelSafe? What size for sprint?, Racing fuel cells Options

[Stark 01]

Hi everyone, I’m getting my 914 back into racing shape. The ATL fuel cell is old and was installed by PO for endurance racing, 22 gallons.

I have replaced everything downstream of the Holley pump, and now thinking of a smaller tank for sprints. (Can’t see myself doing endurance racing, although I would love to).

The Fuel Safe cells are more affordable than ATL, and carry the FIA cert. They can be ordered with the Holley pickup mats, which also eliminates the need for a 100 micron filter before the pump.
Does anyone here have anything negative to say about them from personal experience?

What size tank should I get for my 914-4 built engine (2.0)? I’m thinking 8 gallon?

I've just gone to ATL from Fuel Safe as I was getting debris that clogged the small screen filter in the pickup line ahead of the fuel pump. Sure enough got debris from the ATL also but ascribe that to the new installation. I run a mix of leaded 112/115 race fuel with 93 pump gas that has ethanol, about 25% race fuel...guessing the ethanol slowly degrades the foam & is the source of the debris.
As to capacity, 12 gallon for a /4 should be right. You have to think about the last laps of a session in which the fuel sloshes to the left on long right hand sweepers and you suck air. Dual pickups in a tank require dual fuel pumps--surprise surprise! Soo..get the sump option that has check valve doors and a single pickup in the sump box. Then put on a good capacity pre-filter in the pickup line where you can get to it to backflush it out....I just went with an Aeromotive with stainless mesh insert--expensive at $147 but I think worth it. You can choose 100 micron or 40 micron.
Rock ON!

Thank you for all that info.

I know the foam deteriorates, and the bladder can dry out and crack, but I had this thought about all the advice to drain the fuel. I used to be around some classic airplanes that had bladder tanks, and the advice was to store them full so they don’t dry and crack, but the advice here is opposite. Anyone know why?

I found a new product by Holley that sounds awesome:
A mat that lays at the bottom of the tank. It allows fuel to seep in, but not out. According to Holley, it will scavenge from anywhere mat is touching fuel. Also acts like a 40 micron filter. I guess you would still need foam on top though. Fuel Safe allows you to purchase it installed, in leu of a pickup box with baffles. Downside is it does have a service life too.
