Right.

ive just brought another 340 b14

the guy laid it up a year ago. and now it wont start. it'll run if you put fuel in the carb.

Now ive removed the fuel pump from the block and hand pumped it. 5 minutes later form having ntohing spraying out of the top, it now sprays evenly. so its been bolted back on to the block and pumps out fine when cranked so i can safely assume the fuel pump isnt fubar.

now with the pipe connected back to it and removed from the carb, nothing travels up the pipe.


So im thinking blocked pipe only?

Any one else got other ideas.


And for more information:

shes a 5 door
1.4
Catalyst model
Heated seats
Lumbar support
5 speed box

If pump's valve is dead it can pump fine to bucket but it could fail pumping upwards if air comes trough carb to pipe.

However blocked pipe sounds more like it.

edit: fabric covered pipe could be collection of holes instead of pipe, even it would look fine on surface.

well from carb to pump, i have a rubber hose.

with the pipe of the fuel pump( this is the carb to fuel pump pipe) it will spray skywards nicely. Hence me thinking it cant be the pump. I was already prepared to have to buy a new pump. but thought i'd check first. now i can swap to another bit of hose as i have some vaccum hose i can play with and for a minute or so that might be an idea to test if its blocked pipe


any other ideas?

As it's stood for so long, the petrol could be stale. The additives evaporate very quickly from modern petrol, try running a hose from the pump to a jerry can of fresh stuff and see if that works.
This is all assuming you've already checked for spark.

Filthy,

No fuel reaches the carb. sparks fine as it runs if you put petrol in the carb eg pour some down the barrel.

it'll flow from the pump fine out of the top hose attachment but the minute the hose is on nothing seems to go from the pump and travel up the hose.

i'll try later with a bit of the vacum hose from my other volvo. which is see through. see if it travels or not

Have you taken the pipe off from the carb end only to see if it is getting up to the carb? if it gets up to the carb then the little filter behind the union bolt could be full of muck stopping the fuel getting in the carb at the start of it's run.

Its alright she runs,

i took the feed pipe of the pump. cut the fabric bit of and stuck some vaccum hose over it pumps fine now. yet that hose was perfect inside and out.. so im lost as to what it is.

Good, maybe pump did not like from that hose?

But remember, if there is fabric it is not fuel hose

its that fabric over braid stuff. all i can guess at is mall airleak in it

yet this vaccum hose is a tad to big for it

Halfords fuel injector hose. Not only is it hard as nails and available in a variety of bores, but it also comes with the world's best jubilee clips. And I have a trade card
