My second brand new pump in 200 miles has become incredibly noisy and I am considering going electric.

Has anyone got pictures of one fitted to a Griff as there doesn't appear to be much room to install it?

From posts on Pistonheads the two pumps normally used are the Peugeot 106/Citroen Saxo or the Astra Mk4 TRW.

Do electric pumps run continuously or only when the steering wheel is moved?

Are they noisy (the reason I am ditching my standard pump)?

Advice greatly appreciated.

Thanks for the replies....

carsy, plenty of room under the headlight pod but I think access would be really difficult unless the pod was taken out.

Precat, that's a neat install you have there but not possible on my car as the Serp engine has the header tank in the same position. However if I could re-route the bottom hose I might be able to mount the pump to the left of the position you have chosen.

From what I can see on your pic. your belt only seems to be driving the alternator and water pump, not the idler pulley. I'm surprised there is enough 'wrap' around the water pump pulley to prevent skidding?

Back to the drawing board......

Peter, is the Vectra pump the same as this Astra Mk4 pump?



Does your pump run continuously or only when the steering wheel is moved?

Does your pump give variable assistance the more the wheel is turned or is the assistance constant?

Sorry about all the questions but I have no experience of electric pumps.

Thanks Peter,your pump looks the same as my picture.

May be a good idea to make this a winter project rather than waste this top-down weather.

Thanks Matt, I've been Googling all morning trying to find out what size fuse to fit. Looking at the connection cable I guessed it would be a big one.

Thanks Spend, probably would help if I could find out what size fuse is used on the T350 as the same pump is used on that car.

I intend to take the main power feed from the starter motor terminal to the relay as its nearby. The switch feed to the relay has to be live only when the engine is running. I believe people use the alternator for this but which terminal would it be?

I don't think you can do that from the starter > alternator (oops brain v finger error)???

I've always advised using the positive wiring circuit from the purge valve ~ that is activated by the fuel pump relay, so you get a quick prime when the ignition switched on, off for cranking & then running when the engine is spinning ~ so apart from the extra brief prime just like the mechanical pump availability (apart from on coast down I suppose).

Just noticed your edit Dave, does this mean that it is OK to take the main feed from the starter solenoid terminal and the relay trigger wire from the purge valve?

Asked on the T350 forum and they say the fuse on their cars is 75amps.

Jes, the pump with the remote reservoir would be easier to find a home for, as you have, but unfortunately I already have the other type of pump. I'm hoping to relocate the bottom hose to pump under the top front crossmember and then sit the pump on top of the crossmember.

Thanks Dave for confirming the wiring connections. Next job is to have some mounting brackets made up. Fortunately my pump came with its original mounting cage so that will give me a good start.

I just used 90/100mm u bolts, stuck some rubber on the pump and clamped/suspended it to the monster plate attached to the chassis.
I like that idea, the makers mounting cage is a bit OTT.....thanks.

Ian, I didn't carry on with this install and am still using the hydraulic pump. Problem I found was that on the Griff with its sloping radiator there is little room to mount the pump. The other snag is that the bonnet roller cross-bar limits the vertical space for the pump. I have seen a pic. of a Griff where it was mounted in place of the washer bottle but decided it wasn't for me.

I wouldn't say that it couldn't be done but as yet I'm not sure how.

If you have any brainwaves I would like to see the result........good luck.

Well that really is lateral thinking! Would your pipe runs be in copper or flexi hose?

I haven't been out to look as it's bucketing down but is there room in front of the radiator? If you can get an oil cooler in there perhaps there's room for a pump?

Looks like you intend moving the expansion tank to make room for the plate. Would be interested to see pics. when finished.

How anyone can say they prefer non pas is beyond me. Even driving at speed i found it a pain going round corners. Now its a total joy to drive.
I wouldn't go back either.

Ian,thanks for the latest pictures, finished result looks very neat. Can't copy you however as my expansion tank is in the same location. At the moment I'm using the standard hydraulic pump but it's very noisy (even though it's new). My car is away at the moment having a Canems ECU fitted so there may be some space once I ditch the charcoal filter in the inner wing.
