fuel pump life expectancy ?
« on: 01 August 2011, 05:55:25 PM »
Just a round-robin from those who have a great(er) experiance, (than me).
Im trying to get an understanding of the life expectancy of a fuel pump.

yep thats right mine has failed, circa 135,000 miles :( and im trying to find if its worth getting a 2nd hand unit or not ?

ALSO HAS ANYONE got the ring removal tool the would be prepared to lend/hire to me :lol  he says hopefully?

Arghhhh

I've just typed a reply on my iPhone and pressed the wrong button

So the short answer is....

140000miles is around the limit for a 9000 fuel pump

You can get a replacement kit for about £60 and I did have one that lasted about three months - sent back as faulty.
When you fit don't forget to take the dust caps off the pump  ::) and be careful how you take the flower pot out of the tank so as not to bend tha actuator arm.
Pour a kettle of boilering water over the ring and connectors and then have a cup of tea while it cools and thenm mop up the water - help soften up brittle the plastic.
You don't need the special tool - a lot of people use eth water pump pliers but I used large screwdriver and mallet and just knocked it round until it came loose. Pull the fuel connectors VERTICALLY up and not at an angle or you will break them and I found a spray with WD40 helped together with a slight twisting motion back and forth. Pull the locking tabes away slightly - it will become apparent when you look.
Once refitted listen for the pump to prime.
Have you checked fuse adn 12v feed to the pump just to eliminate?

I fitted a used one from saabjaguarspares (the complete pot) lucky as one of the retaing tabs broke as soon as it was moved- plastic had gone brittle.
I made up a tool to fit the ring so that went well with no broken tabs on the ring. It was well in there and took quite a bit of leaverage to start the ring moving. Took about 20mins once i'd removed the rear seat back (made the job so much more comfortable than laying on my stomarch in the boot) and everything else out of the boot.
Primed the system and it fired up 1st time.
The strange thing was there was a lot of plastic ribbon about 3-4mm wide wrapped around the float arm - got no idea where that came from.
