My fuel pump has gone on my sierra cosworth 4x4 and I need to replace it and the wiring. It is currently just a standard pump but I'd like to replace it with a Bosch 044. Does the car need to be remapped or can I just upgrade the fuel pump?

 

be aware there lots of fake ones on the bay, get one from good well know supplier

 

MSD will supply you with all the correct parts loom and fittings. No remap required.

That's great, thanks, will get one from MSD.

 

if your own pump has been struggling it will be worth checking the fuel pressure and mixture at idle after fitting a new pump and filter...always better safe than sorry,although its better to overfuel a tad than run lean

 

Above post is a must.

 

how do you test fuel pressure? i have a problem with my fuel tank, i replaced it recently and now it's not venting properly (petrol squirter keeps clicking off when i fill it up). I dropped the tank yesterday but couldn't find anything wrong but i'm guessing this could have caused the fuel pump to stop working, anybody had a problem with this before?

 

Was it a aftermarket tank with rhe square bottom?

 

yes it was
