How to fit rs2 fuel pump

[andyg plym]

Just received an rs2 fuel pump with basket ( thanks dobin )

I presume it's best to use the rs basket, but how do you get the old one out ? Is it a push fit? Clipped in etc ?

Same with the wiring ? Any mods needed ?

Finally, is the banjo on the s2 fuel line a straight fit to the rs pump ?

Thanks all !

Basket rotates and lifts out, not an easy job and even more difficult to get back in. Have a look at Daves guide here http://www.s2forum.com/forum/showthr...t=c4+fuel+pump

Hose will be a problem, i know for the 044 fitment i had to replace the original hose with an RS2 version. See the bottom of this thread http://www.s2forum.com/forum/showthr...&highlight=044

I believe the coupe pipe fits.

Have a look on my avant thread linked in my signature. The first thread lists which post for the fuel pump.

Check out the C4-related pdf that mcandmar pointed you to: http://12v.org/urs/Fuel%20Pump%20Tes...eduresRev3.pdf

Also there is the attached (based on a post from DougS2 at MRC) and the Audi 90 fuel pump removal guide attached.

If you don't have to remove the basket, then you might be able to use this:

The diameter of the RS2 pump is the same, so you can use that and secure the RS2 pump using another method. Saves a lot of hassle.

What about the pipe actually connecting to the pump ? S2 are push on and use a jubilee clip but I guess I need to buy a banjo connection ??

Yes, you can use a banjo and jubilee or there is part that is designed for the job:-

fuel pump

andy i took that non return valve off and fitted it onto 040 pump which it does not come with one. if you run the car without a return valve fuel pressure drops off everytime you start car up you have to keep turning over until fuel comes up the line.
i found this out myself got my fittings on ebay

Hi mate don't forget my pm I sent to you

Just went to a local Bosch specialist and they had nothing I could use, any ideas where to look now ? He said I needed an m12x 1mm fixing.

Any ideas ? I just need the banjo and bolt don't I ? Or do I need more ?

Dont Know

[mcandmar]

In theory you could get a banjo and length of hose and make one up but lifes too short, just buy the RS2 hose and do it properly..

[andyg plym]

It's the bolt that I'm more concerned about....

Update: so I managed to find an elbow with the thread I needed for the pump, the elbow itself requires a larger diameter hose,is the rs2 hose bigger than the s2 ?

Also is it essential to have a fuel return valve ? The s2 doesn't

Bump

Want to fit this as soon as, the question is:

Do I have to fit a return valve to the pump ?

Thanks guys
