Fuel line replacement

[cyphrsbird]

Sorry to ask incredibly dim question....want to replace a fuel line on the van...want to ask... is there any problem with air entering the system or should I "prime" the new bit of line?
I know this is probably the dumbest question so far...but I'm a girl so I can get away with it

Thanks in advance.. Mara

There's no need to prime anything following replacement of the fuel line. The first time you try to start the engine afterwards, you will have to allow the engine to turn over a few times before it fires up. The mechanical fuel pump needs time to pump petrol through to the carburettor.

should start really as the carb will be already full, but it will probably spit and stop again. which fuel line are you changing?

[cyphrsbird]

...its the one that comes in from the solid line which is disappearing under the van to what looks like it might be the fuel filter - a big black thing on top of the engine. Sorry about the basic, not tech descriptions but this is a really sharp learning curve for me at the moment!! I do have a haynes but it never seems to have anything in it that I need to know it kinds of assumes a bit of knowledge which I just dont have.

to be honest, if you are not sure where your replacing the pipe to and from, should you really be doing it?
not being funny, but petrol is , erm, a tad explosive (and fecking expensive) .
there shouldnt be an issue with air, like rozzo said it should start with whats in the carb, and pump and as long as you are not replacing the whole line from the tank, it will pull through the fuel by the time the carb is empty.....

just be really sure you are safely doing the job, because fuel lines are the biggest cause4 of van fires .If in doubt, get someone to help you........

Just rang my friends husband (as I suddenly got reminded he is a mechanic) I'm replacing an approx 7" section which goes into the carburettor , as he is now also going to service the van for me and let me watch what he does he he said he will do the line at the same time so I can be sure the van is safe before my next trip away

I've done my today following a fuel pump failure. Took about an hour including changing pump and pipe from pump to carb. Plus new filter. cost about £65 total £58 was pump (pierburg) inc vat.


Just as an afterthought: Jack the back up and put ut on axle stands or ramps, makes life a great deal easier if the fuel is forward in the tank and the tank is not full.

It may sound obvious but there are those who have taken a fuel hose off the tank only to get covered.

Did she start Ok again after, I only have one small section of pipe to replace - about 7" pipe going into the carb - good idea about tilting the van forward, would never have thought of that!

If I want to stop the flow of fuel from a disconnected fuel hose, I stick a 1/4 inch Philips screwdriver in the open end. It beats messing around with jacks, axle stands or ramps.

Years ago someone told me to stick a pen top in the fuel hose of my bay.....
I really should have checked to see if the pen top was one of those new fangled anit choke ones.. the ones with a hole all the way through....

The reason for the axle stands was not just to get the fuel forward, but it's a sight easier to get under the vehicle to get at the clips as I changed the fuel pipe end to end, the other reason was I'm not as svelte as I was a few years ago.

In answer to the did it start ok question, yes it did after a few turns of the starter.
