i have a weil mclain qb-180. the problem im having is im not

This answer was rated:

i have a weil mclain qb-180. the problem im having is im not getting fuel threw the pump. i have good fuel to the pump and nothing to the nozzle or out or the bleeder

Rick :

Welcome, my name is XXXXX XXXXX I will do my best to help you with your issue.

Rick :

How are you bleeding the pump? are you bleeding with the burner running?

Customer:

i am using the bleeder on the forward facing bottom side of the pump. yes it is running while attempting

Rick :

you're bleeding from the bleeder indicated in the picture above?

Customer:

yes that is the bleeder i am using

Rick :

Ok, then the most likely culprit (assuming the pump is functioning properly) is a clogged pump screen

Customer:

ok. where is that located?

Rick :

What is the brand and model of your burner?

Customer:

the label says weil mclain qb180 on the burner

Customer:

the pump has suntld a2va-7116 on the pump

Rick :

That's an old burner. There are 2 hex screws on the face (left side of burner) of the pump. You'll need a new gasket and probably a new screen. You won't find any plumbing supply houses open today so you won't be able to get parts until tomorrow

Rick :

I'd remove the cover and bring the screen and the cover with you to the supply house to get the right parts

Rick :

Of course there's always a possibility that the pump has failed

Customer:

the hex screws can be seen in the pic you sent by the bleeder and opposing side?

Customer:

the pump sounds like it is spinning ok and no abnormal noises from it

Rick :

yes left side

Rick :

Your description doesn't rule out a bad pump

Rick :

we would check and replace the screen first

Customer:

ok. i had that off earlier and didnt see a screen, just the shaft and needle bearings in there

Rick :

There should be a screen. If not you probably need a new pump.

Rick :

The screen is cylindrical

Customer:

ok thank you i will try it
