fuel pump

[minilady]

how do u know if the fuel pump needs replacing,i have the pump that sits in the engine

[The Marcos Graveyard]

Disconnect the hose from the fuel pump to the carb, put the end of the hose in a glass jar, turn the engine over and see if the pump pumps any fuel into the jar.

it does but cuts out when it warms up

[just_st3v3n]

check to see if the fuel pipe is touching of the exhaust manifold... happened me before.
if it is it means that the heat from the exhaust (right under the carb) is evaporating the fuel before it even gets to the carb... fuel shortage...
check that. u can just bend the pipe out of the way sort of......

pipe out of way,any more ideas,it just cuts out when she gets warm in the engine,leave it for a minuteor two and she fires back up she has me puzzled

[woody]

What carb are you running? Is it cutting out at idle or when driving?
Sorry just read the other post, sounds like fuel starvation alright. Have you any inline fuel filters,may need replacing? If your running a HS carb cheak the float chamber for dirt.

[minilady]

not running any filters that i can see, changed the coil to see no good, where do i start looking for fuel stravation, i've taken the float chamber off and clleaned that, checked fuel pump, checked the fuel pipe, seems petrol gets to it but after a few mins she stops,wait for a min and she fires back up

[woody]

It sounds like the floot chamber is not filling up fast enough.Either the fuel pump is on the way out or the fuel line is partly blocked. Try blowing out the fuel lines ,if that doesen't work it looks like the pump.

thanks for that ill try that in the morning,will keep u posted,are pump easy to come by

[The Marcos Graveyard]

Is it a mechanical pump or an electrical pump you have ?

[minilady]

not sure machanical i think it sits in the engine towards the bulk head with two nobbles comming from the top

[The Marcos Graveyard]

Yup, thats mechanical all right, I'll check in the garage and see if I have a spare, down in Cork at the mo, so it might be tomorrow till I get a chance.

[minilady]

just looking at the hayes manual and juding by that i have a mechanicalfuel pump 800 or azx series type, are they easy to come by,and easy to replace,if not i need HHEELLPP

still available for the usual sources at less than 20 stg. if you have an LCB or 3:1 manifold then its tricky to change. the single pipe exhaust manifold doesn't usually present a major difficulty.
