AS ANY ONE ON HERE CHANGED THERE FUEL PUMP FOR A UPGRADE ONE ON A CLASSIC 93/96 MODEL, IE: WALBRO, IF SO HOW HARD IS IT TO DO? AND WHATS INVOLVED, DO I HAVE TO REMOVE THE TANK TO DO THIS,

 

no easy job.. the pump sits in a cage which is attached to the top plate of the tank.. back seats out, little inspection cover off, remove pipes and electrical connection.. undo the little nuts and lift the whole lot out.. change the pump with cage on bench and refit.

Can give more detail but not at this time of night

I would suggest reading it a few times, so its clear in your head in whats needed to be done.

 

^ What Simon said

IIRC the hardest part is getting, I think it was the middle pipe off the top of the unit.

Other than that, it's pretty straight forward.

Might be wise to source a new gasket in case it's perished though.

 

tend to find if you use pliers and rotate the fuel pipe gently they give a satisfying click noise as they come unstuck from the metal pipe and then pull off fairly easily.

the one nearest the front of the car has a clip.. you press the two white bits of the clip on either side in and the pipe comes off..


Also worth unplugging the fuel pump and running the engine until it stalls and then removing the feed in the engine bay.. this will releave the fuel pressure in the pipes so you only get partially covered in fuel rather than drowned when you take the pipes off

 

or you can releive fuel pressure by taking the petrol cap off you will hear a loud hiss as the pressure goes

 

I swore and swore some more at it until the pipe came off, grazed knuckles moment

Thats what I did.

 

that releves pressure in tank but not between pump and engine

 

Very little petrol came out the pipes when I change mine, although my car had been sat overnight F/P drops off slowly I believe. So would have been liw pressure in the pipes.

Could well be wrong on this though.

 

thanks to you all, very helpfull tips and diagrams,
