914 Fuel Cell installed

[BoxsterGT]

Does anyone have a fuel cell installed in their 914 in the stock location?

I am planning to do a Fuel Safe cell and would like some tips and/or photos of same.

I know there are no filter screens in the new aftermarket tanks, but I have a Pre-Filter kit for the Dansk 911 tanks and will try to adapt this to my 914.

I have a 3.6 motor fitted, and this needs both a Feed and a Return the entire length front to back.

Easiest bolt-on I've seen is this one:

Spendy, but it doesn't get any easier.

But if "easy" isn't your priority, then sure, it can be installed. Just takes some fab skills and understanding of the systems.

I like "easy", especially since I already have AN8 adapter fittings to Metric....



Thank you Greg.

Why do you want a fuel cell in the stock location? Are you going on-track where a cell is required? If so, read the appropriate rule books to check your options for location, capacity, mounting, and such.

The default location for a fuel cell in a 914 racer is on the floor of the front trunk. It's relatively easy to fit a standard box-shaped tank there, with room for pumps and filters and such. On the plus side, it moves the fuel weight lower in the chassis. On the minus side, it moves it in front of the front axle, and the weight changes as you use fuel.

There are vintage race series that require the fuel be in the stock location or even in a stock tank, but also be protected by a fuel cell. Those are usually made by specialists, and cost quite a bit more. Some will cut the tank open, build the fuel cell inside it, then seal (weld?) it back together again. Some just make odd-shaped tanks to fit in the stock location. They will hold rather less fuel than the stock tank, as the foam and bladder take up space that would have been occupied by fuel.

Unless required by the rules, I would probably keep the stock tank. If the rules require a cell, I'd probably put it in front.

Then again, if you just want a fuel cell in the stock location, and have the money to throw at that, it's also a known solution.

^^^Yup, mine's in the front trunk.

Downside to the Patrick cell is that it's bespoke. That means you're beholden to Patrick to have that molded cell available for as long as you plan to race the car.

Were I to build this car again from scratch, I'd likely cut out the bulkhead between the stock gas tank area and the front trunk to move the cell as far back as possible. Then I'd build the cage to the struts, lower and upper and across, for chassis stiffness around it.

However, the regs that the car was originally built to did not allow that. And this car is only racing historics now so eff that effort.

The old race car and the new one both have cells in the stock location. One is an early fuel safe, similar to PR above, the other (from what the PO told me) was a bladder designed to fit the stock tank...

New race car:



You can see the plumbing routed to the pump just over the battery ().

I sold my car and then bought it back. When I bought it back, it had a PMS Fuel cell in it. The only useful feature that I liked was that it never starved for gas in a corner with a half empty tank. The downside is the bladder has a limited life span and has to be replaced, plus its impossible to get rid of fuel vapors in the passenger compartment. It's designed for the track, not for street use.
It's also only 10 gallons, versus a stock tank is 13 gallons.

There was a fellow on one of the classifieds not long ago who was selling one of the Patrick units. Can't remember much else - but if you were to put your mind to it you'd find it . Maybe 914 world classifieds?

In my conversion from track-to-street, I have recently removed my fuel cell and installed a found, clean original tank. Changing the styrofoam and the bladder became a bridge too far. I"m looking forward to driving the car!
