KiwiBrumby Posted July 27, 2018 Share Posted July 27, 2018 I have just lately noticed the electric fuel pump runs in short bursts at times, the rest of the time it is normal - any theories out there? The motor seems to still run just fine -standard 1984 EA81 i.e. Up until a short while ago I heard the pump going steadily, like tick-tick-tick-tick-tick etc but now and then it goes tick-tick-tick-tick-tick-tick-tick-tick-pause-tick-tick-tick-tick-tick-tick-tick-tick-pause-tick etc I haven't counted but it seems about 8 or 10 ticks then a pause of half a second then 8 or ten ticks then half second pause Quote Link to comment Share on other sites More sharing options...

Dee2 Posted July 30, 2018 Share Posted July 30, 2018 Best guess is that the pump may be going out. Problem may not be bad now but could likely get worse. You may want to start shopping for a replacement in case you need to get one in a hurry. Quote Link to comment Share on other sites More sharing options...
el_freddo Posted July 31, 2018 Share Posted July 31, 2018 I can't hear my pump in the '90 brumby except on start up. It's generally quiet all other times unless sucking air when tank is extremely low. Generally with what you're experiencing I agree with Dee2 that this is a sign it's on it's way out.

jono Posted August 1, 2018 Share Posted August 1, 2018 Put an aftermarket pump on if you wanna hear its heartbeat. Happy I went to pressured tank propane Kiwi, might be a number of things and given the age of our old girls it would not hurt to inspect and flush out fuel lines from front to back so you know they flow well, replace any rubber fuel lines as they can deteriorate on the inside and cause grief. Chuck in some quality fuel cleaner for a tank or two THEN replace fuel filter - that;s the fuel side Could be electrical too. Maybe run your radio power from fuel pump pos power, see if fuel pump is getting constant power Does it vary depending on how full or empty the fuel tank is?
