Fuel Pump

A change of electric pump and location is one of my top jobs this year before I start using the car in anger, I suffered terribly with fuel vapourisation last summer with my cheap facet pump located by the N/S headlight. I'll be following your progress with interest Stina.
 
Fitted a facet type ( not facet make) on panel where coil is. Running correct modern fuel hose and clips in place of mechanical pump. Though clicks away on idle..no overflow, can't hear it above 4-5 mph.
Wired from fuse box before fuse..has it's own line fuse. Filter sealing being only issues as the brass sealing ring on nylon tends to leak.. So now using fuel hose both sides of it. Not visually perfect but seems to work so far.
Not worried about accident leak eg broken fuel line as even the mechanical unit was fitted under a very hot exhaust system !
Looking to buy a fire extinguisher later just in case of accidental issues ..but it's survived 40 years now,,I ( touch wood) not bent anything since I started driving in 1968. So.. Not expecting anything to change..hopefully.
 
Do you have a link to the pump you bought , or a picture of it fitted ? Or anyone else recommend a model , i've looked on line and their's quite an array . What pressure would it need to be , 3 to 4 psi ?
Ps i'm only interested in under the bonnet sucker types . :D
 
I fitted a Facet at the back beneath the tank, like on the NADA cars. It needs a longer reserve cable, as the tap is now back there too rather than in the engine bay. Previously I had the same type of electric pump in the engine bay next to the coil, but it was too loud, plus I didn't like the idea of being involved in a front impact and the pump still expelling fuel. I can hear it on start up, it takes a few moments to prime before firing up, and I it works fine for me. I did end up having to use plumpers teflon tape to get the fittings supplied in the kit to actually seal to the pump body, which hasn't dripped since. I recommend this bit of kit and where to mount it. There are some pics somewhere in my members projects thread.
 
hi stina-fittedfacet pump to rear of car and wired to swich on dash -but noted that old fuel lin ran two inches from manifold so re routed with new pipe-intend to run on mechanical and if needed switch to electric but have used car since re routing and have had no problems -just to add if i disconnect mechanical pump and hide electric switch it would act as immobiliser---andy
 
Stina, have a read of this. It's a bit more work than perhaps you'd envisaged, but it works well as it's a copy of the factory export system. viewtopic.php?f=5&t=7342.

The pump doesn't cut out when the float bowls are full because there's a return line to the tank, this helps keep cool petrol flowing through the carbs when it's hot.

I've got pdf copies of the two articles linked to if you need them.
 
A pump (even the correct type) placed within the engine bay will be predisposed to vapourisation, just like the mechanical pump is.

The only reliable place to locate the pump is beneath the car at the rear, ie under the tank.

Context however is significant, all things being equal. From my understanding, U.K Summers are rarely more than warm (25 degrees C), so the degree and frequency of vapourisation should be rather less, so mounting the pump in a less than ideal location, i.e. within the engine bay, may not present problems on a frequent basis.

Thanks Paul , i do hear what your saying , and i'm still batting ideas about . One thing that interested me in your write up is "quicker starting" that is one thing i'm looking for out of the conversion if/when i go for it . I think the electric pump priming will take care of that . On the other hand though i don't suppose it hurts for it to spin over a few turns to prime the oil system any way !
 
Fitted electric pump.. Worked a treat for couple of weeks then .packed up. Replaced with a different electric pump type.. That packed up even sooner!
Refitted mechanical..so far so good.
Came to conclusion pumps were designed to run continuously with fuel not being used going back to tank. Since no return fuel flow....pump is Running against full pressure stop once carbs full.. No cooling fuel flowing so basically just overworked and cooked!
Should have fitted the other type that are self pressure controlling and don't overheat as fuel not used to cool pump motor. ..oh well facet pump is answer so of the mechanical one fails,, !

Bad luck ! What were the types of pump you fitted , so as to avoid ?
Edit
Thinking about it their is a return to tank , or is yours removed or something ?
