Re: Fuel Pumps and Petrol / Alcohol Mixes

Further to my original query, the outcome of the fuel pump study is that the pump shown in the attached photos is now being used by GMH here. Apparently, there have been many warranty claims (not a Ford problem, for some reason) and this is the solution. I don't know if it's right, wrong or indifferent, but I've been told that Australia isn't running the cocktail fuel mix that some other countries do and that is causing the problem. I'll leave you to judge that for yourselves.

I'm using these pumps in my car for several reasons, including the fuel issue. The unit comes complete with the pump, screen, swirl pot and level gauge. It incorporates a spring mounting, so that it will fit into various height tanks. It's a shame it isn't made of alloy, but it won't be visible in my installation, so I can live with that. If I ever do have to replace one, I can buy it at any GM dealership. Installation is snug, but it fits.

The level gauge arm has been taken off in the photos. The sensor will go too. I'm using separate Turotest float type sender units.The pump is a high pressure submersible type, so plumbing is simple. One supply line to one end of the fuel rail and one return to the tank for each side of the car. This gives two fully redundant systems. The return line feeds into the surge pot. The pickup is on the underside of the swirl pot, which will sit flat on the bottom of a small sump area in the tank. In my DRB, there's just enough room to sneak one in. It should suck the tank pretty much completely dry. In addition, there seems to be a built in sensor that will stop the pump drawing from the tank and only draw from the swirl pot when the tank is empty. It should draw right down to fumes. I'm having a switch for each pump on the dash. Generally, I'll switch one on at a time for normal use, but switch both on for a bit of fun, say, drag racing, where fuel use could be up.

I don't have the part number here just now, but I'll post it soon.

Regards,

Lance
