Dead Fuel Pump

[Guest jwts]

Hi,

 

The fuel pump in my SuperSpec is dead. I think it has seized due to corrosion after sitting in a damp garage for nearly four years.

 

The part number on it is

 

1S7U-0350-B1A (the B1A is suspect since it is overwritten with printed XXXX)

 

Assuming the whole number is correct it was originally for a Ford Mondeo V6 circa 95-99. A new pump/sender assembly for this engine will cost about £105 from Partco.

 

Here are some pics:

 

 

 

 

Do I have to replace it with the exact model or can I substitute another similar pump? It doesn’t fit in a clip or bracket; it just hangs in the tank by a piece of flexible fuel pipe.

 

If I can substitute another pump how do I choose one? There are hundreds on the FuelParts site alone. I don’t understand why there are so many, surely all a pump has to do is be able to deliver a certain amount of fuel per minute and generate a certain pressure, so why so many shapes and sizes?

 

Does anyone know what fuel delivery spec and what pressure a Rover 2ltr T-series engine needs? The pump fitted was spec'd for a V6 Ford so it wasn't what the Rover designers had in mind.

 

Ideas, suggestions, recommendations, etc, gratefully received .

 

Regards,

have you tried your local scrap yard? always a good parts site for hoody builders

im pretty sure you can change it for any pump of smiliar power. even if its higher power it should matter. Just obviously dont go for a smaller lesse rpowered pump and you should be fine.

I would not pay more than £65 as I got and external one for that and internal ones are less.

 

Do you have a swirl pot in the tank as some pumps come with them built in to fit in the tank.

 

webber do one with sender etc as one unit for £110 ish.

 

My in tank ford pump was fitted to the metal tube and had a filter on the bottom looks like a small bag

Hi John,

 

Just looked in the Haynes manual, Rover 2.0ltr EFI MEMS unit requires max pressure 4.1 bar, constant pressure 3.0 bar +/- 0.2. It doesn't state the delivery rate though (GPH).

 

Hope this helps.

Al,

 

I never thought of looking in the Haynes manual . I decided to go for a pump I found on ebay. It is physically very similar to the one I have and has a operating pressure of 3 bar and a delivery rate of 160 litres/hour.

 

I have driven this engine in a Rover 420 and it easily does 200 miles on 30 litres so a quick bit of mental arithmetic says it should do 1000 miles on 150 litres. So this pump should be good for at least 800 miles/hour or better . I can live with that!

 

PS - I know the calculations above are a bit iffy but I still think 160 litres/hour should be enough . I hope the ECU turns the pump off when the max presure is reached?

 

Regards,

More than enough..... Even at 100mph you would only use a max of about 20ltrs... & your engine should get better MPG than mine!
