I was going to fit the uprated FSE fuel pump I bought last night, but no matter what I did I couldn't stop it pissing fuel out of the fuel lines it connects too.

Ignition was off obviously, and the power connector removed. I tried undoing the fuel filler cap to try and release any pressure but to no avail. As soon as I took off either of the three fuel lines where they enter the top of the mounting plate, I got squirted with Optimax. Not very pleasent!

So whats the secret here?

Let it drain out of the pipes..

Cover it with a rag... leave it a while after driving before doing it..

You couldn't let this drain, it was more a torrent than a dribble.

I guess I just need to let it sit for a few hours... by which time it's dark and too late to do it...!

David_Wallis

you can... put a rag around it when you do it...

POC

The fuel lines are pressurised, something like 2.5bar?

Take the plug off the top of the pump, start car and let it idle until it stalls.....This will suck all the fuel from the lines and de-pressurise the system.

Remove pipes, a little fuel will come out but not the torrent you are experiencing.

I did this recently, but forgot to depressurise it all first, was like a fountain too , just covered it with a rag and let it drain, as David suggests. It will only drop out about a pint or so.

Hope this helps

Thanks Paul, never thought of doing that!

Did your original pump look like this?



I presume the two power wires connected to each lug on the original need to be spliced into the bare wires on the replacement pump?

I'm a bit dubious about doing this for some reason, since it's all submerged in petrol (keep having visions of a very loud bang!).

POC

Yup thats right, I used male/female electrical connections and crimped them to the pump wires.

For some reason it doesnt blow up

Make sure its all back in the tank before reconnecting the battery etc.

POC

....as a side note, dont use things like insulating tape etc... could be disolved in the petrol, doubt that would be good for the fuel system.

Looks like Turbosport is working again (not).

Any idea why there are four wires (two per connector) on the original, but only two on the replacement?

Also, my replacement is vastly smaller in size than the OE pump. I guess it still fits ok.

POC

Two of the wires power the pump, the other two feed the fuel sender (for your gauge), essentialy there are only two the connect into the pump, the second set of wires take a feed from those. The pump only needs a pos and neg to work.

My new pump was about half the size.

Marvellous, thanks Paul. I feel much more confident tackling this now!

Now I don't suppose you replaced the fuel pressure regulator as well, and can tell me exactly where the OE item is in the engine bay? I can't see it for love nor money (a pic would be good).

POC

No probs Tim, its a daunting job, but very simple and very straight forward

I havnt done the regulator yet, planning to over the next couple of weeks, maybe you can help me out on that one
