Trunk mounted fuel pump
Has anyone mounted their electric fuel pump in the trunk, is it a good idea? I have a Barry Grant 220 and mounted it inbetween the diff and rear cross member. It was the only protected spot under the car it would fit. Gear oil leaked out of the weep hole on the diff, after some tight cornering and sprayed on the pump which fried it.
The diff was filled to the proper level with RedLine synthetic (I did it outside of the car on a level surface) so I don't think it was overfilled. Anybody else experincing leakage from their weep hole? |
Oh dear god...do NOT mount the fuel pump IN the trunk!!!!!!!!

ROFL...looks FABULOUS, seriously, looks really good, I just don't know if I want my luggage THAT close to the fuel pump...LOL
|
Does TWA800 ring a bell? Fuel vapors form in closed spaces. Fuel vapors go boom.
|
Gas lines should never be run inside any car. Way to dangerous ... but any Cobra is dangerous by design :LOL: :LOL:
The BEST location for an electric fuel pump is below (or as low as possible) and behind the fuel tank. This way, gravity and your forward motion increases the "pressure" at the fuel pump inlet. |
a quality, good looking installation. I know of several racing applicaions where fuel lines, cells, and pumps are in far more dangerous locations. just for example, in many boats, engines and fuel pumps and lines, are all located in closed areas....there are no vapors from a closed system (unless there is a leak). there is no combustion source in a trunk. Externally mounted pumps are far more likely to leak or get damaged by the road than this application will. Great job my man!

cbreez, thanks. I had Roger Bolick do the install before I picked the carbon car up. He does very good accurate work.

Yes, original Cobras...

hmmmm,you know that's a real common scenario....a leaking fuel pump at the same time a battery cable comes loose....
if one thinks about every hypothetical thing that could go wrong in life, even extremely unlikely things...why bother getting out of bed in the morning. |
...and you NEED an electric fuel pump??????
...I know they look and sound cool, but why does everyone insist on using one? Do you REALLY NEED one?
I was going to install one in my 289 and then figured staying with a mechanical unit. These cars are dangerous enough already, if you get in an accident, the electric pump will keep on pumping fuel instead of shutting down the flow like a mechanical pump would. JMHFO. |

...the rest of the fleet just ran with the mechanical pump. |

I have seen trunk mounted batteries shift in two separate Cobras and spark. I have seen a poorly placed battery cable ground out on the rollbar and spark. Sh*t does happen. |

Personnaly i would mount the pump OUTSIDE any confine space and as low as possible so if it leaks the fumes would not get trapped and it would leak on the ground instead of running inside the trunk and seeping on electrical connections.
|
I have to agree w/using a mechanical pump VS the electric on the Backdraft. As mentioned earlier in the thread, there is a safety issue w/the electric pump running after an accident.
|
. . . and Murphy's Law always rules. Why complicate things in the name of eye candy? Yes, it's best to push gas, but if there's no chance of vapor lock, go with the KISS principle.:LOL:

I have to agree that a pump outside the trunk is way beter (MO).I ran a mechanical pump forever and never had any problems what so ever. In my wisdom I changed to an electric pump,mounted to the frame near the rear suspension,and every time I drive the car I worry about the high pressure in the line from the rear of the car and the fact that now I have another source of leaks to worry about on the engine, the pressure regulator. I will be taking the electric pump off and reinstalling the mechanical pump shortly.A much safer scenario all around.So much of the "Hot aftermarket Products" that a lot of us are duped into buying,like fancy ignitions etc, have absolutely no benefit at all other than bling,and of course adding more weight to your car.Simple ,light and reliable,thats my motto!!!
