MG Midget and Sprite Technical - Fuel pump bypassing.

Here's the prob. I've got a photoshoot with one of our Moggy Minors coming up. I need to fit a Facet pump under the floor since the oriiginal pump is not giving enough oooomph. So....
Can I run the facet through the SU pump without it getting blocked? The idea is to use the SU pump as mere cosmetics and to have the facet pumping through it without removing anything. I know I could gut the SU but I'd rather fix it one day (after tiling the kitchen, fixing the aeroplane, mowing the lawn etc etc). The facet needs, ideally, to go under the boot floor for it to prime correctly.
Will a facet pump through an SU or will the valving of the SU prevent flow?

rob,
Your pump should push the fuel through the SU but I would take the valves out, its not much of a job to do, only a few minutes.

No need to remove the valves from the SU pump, they are just check valves and will not imped the flow from the Facet pump at all. See the article, Backup fuel pump in the SU Fuel Pump Articles section of my web site at: http://homepages.donobi.net/sufuelpumps/ (there is also contact information for Peter Cole, who repairs SU fuel pumps in the UK if you want to go that route.

My understanding is the fuel will flow thur the SU pump with no problem....one of the adverts for the faucet pump is it can be a back up pump incase of Su failure during long trips, just move wire connections or flip a switch...something I have thought about doing from time to time.

As they say Rob no problems in fact I have that arrangement on my MGA with the square facet actually under the bonnet sucking fuel from the rear tank through the SU when required. (quite often)
