TR6 Mounting location for electric fuel pump on TR6

[Gliderman8]

At the end of October, I purchased a Facet electric fuel pump to install on my TR6. Its been a cold winter and I didn't feel like working on the install in an unheated garage. Today is the day that I decided to install the pump as the temps are in the 50's!
Just where do you mount the pump?
The base of the pump is too wide to fit the frame... of course I could trim the base of the pump if that's whats required.
If anyone who has mounted the Facet pump can post a few pics of the mounting and location that would be great.
Thanks for any help!

I dont have a facet pump, but I do have an electric fuel pump that I just recently mounted. Electric pumps like to be pushers rather than pullers, so you should mount it close to the tank. I mounted mine just under the rear shock tower on the side of the frame.

Which Facet Elliot?

This one.....

Any reason you plan on changing to an electric?

Correct me if I am wrong, bub didn't the injected European cars put their pump low in the left side of the boot near the tank itself?

With those "brick" Facet pumps, pay attention to their suggestion to mount the pump at an angle. It was explained to me that the internal bits of the pump continue to seal better/longer if the moving parts operate at an angle off vertical.

I'm installing the electric only because of perceived reliability? I mean the mechanical pump was rebuilt when I completed the car and is doing OK but I worry about it failing one day so therefore I thought I'd install the electric.
As for mounting on an "angle" this is what the instructions say:
NOTE: It is recommended that the outlet of the pump
be at least 45º above horizontal. This will
allow any vapor buildup to easily pass

through the pump.

Elliot- I'd keep the mech one if it is doing fine and then wire the electric as a back up when needed
Those Facets can be loud

 

[Gliderman8]

Don- are you saying to run separate fuel lines from the electric to bypass the mechanical pump?

Doug-As for mounting it low in the boot, I just had a look in the boot area.... the bottom of the tank has a fitting that goes through the body. If I mount the pump in the boot, I don't see how I would be able to connect the inlet side of the pump from inside the boot.

 

[DNK]

No, lots of people have set up the electric as back up with just movement of lines.
Somebody will have to chime in on the how

I have had an electric pump like that on my TR3 mounted inline for the last few years. Have not had any fuel delivery issue. It has help on hot start issues.

That is good to know Don. One question: Is the pump noisy?

 

[dklawson]

I'll answer the "noisy Facet" question. Yes. However, if you put the pump on rubber mounts it is a lot better. Unlike an electric SU pump, a Facet runs all the time. You are not likely to notice either when you are at speed. You will notice a Facet pump at idle, particularly if it is on a panel that can vibrate on its own.

I only hear low tic tic sound.

Don- Any chance that's the valves?:excitement:

Before converting to TBI, I had the facet pump located in the trunk on the left side next to the tank. Facet is pretty specific about location relative to the tank outlet. These pumps do a good job at pushing fuel but not so good at pulling fuel. I isolated the pump with rubber between the pump and mounting point. They're not loud per se..... they click.

I only hear this tic tic when the pump is on. I installed the pump more for hot start problems.

I considered the area on the left in the trunk.... but, how did you manage to plumb the "in" line from the tank. As you know there is a hole in the trunk directly under the outlet fitting of the tank that is only accessible from underneath the car. Did you have it hooked up with the stock tank?
Any photos or further advice as to routing the feed line would be appreciated... thanks!

I put my carter pump in the boot, place where described above, thing is you can mount it in the engine bay as long as its at the same level at the mechanical pump, even though its a pusher, it is lower than the tank so it will have a natural flow to it.

 

[Gliderman8]

hondo- You are correct... the instructions with the pump just say to mount with 12" VERTICAL of the bottom of the fuel tank. Anywhere on the frame (longitudinal) falls within those parameters.
So how did you access the outlet of your tank when you installed your carter pump in the trunk?
