Suntec A2VA-7116 Fuel Pump

Hello Everyone,

Is anyone else experiencing a rash of failed Suntec fuel pumps??? In the past two months, our service techs have replaced 5 fuel pumps due to leaks and/or lack of pumping. I have technicians that have replaced 5 fuel pumps in their whole career.

Before anyone asks, yes in two pipe systems, we verify 100% that the outlet line is open. In this case of the 5 failed pumps, only one was on a two pipe system, the others have been on single pipe systems.

So, I was just seeing if anyone else is experiencing the same issue.

We're discussing on switching to the Beckett CleanCut PF20322.

Thank you all in advance.

    Haven't replaced any fuel units in the past few years. Might be a fuel quality issue.

    Don't forget, the CleanCut requires valve-on delay to work. This holds the oil back for 5-15 seconds after the motor and ignition come on, and cuts the oil off instantaneously at the end of the cycle, resulting in cleaner starts and stops. You can add this using either a "PD Timer" which is a cordset having a built-in delay, or by upgrading the primary control. The Beckett GeniSys, Carlin 60200 and Honeywell R7284 controls can all be reprogrammed to include valve-on delay, though with the Beckett you need the Contractor Tool to do it.

    In what way are they failing? Like you mentioned, they are pretty robust generally. I think in my 35+ years at it I've replace maybe 5 or so.

    I was going through them as well. Swithched to Danfoss BFPH and no problems.Think those are dicontinued.

    Might be able to find them as a rebranded Wayne.The new Beckett pump is a Danfoss, look for made in Denmark.

    Are the techs installing the bypass plug on a 2 pipe oil supply and removing the bypass plug on a one pipe supply. If this is not done it could be part of your problem.

    Do not overreact. How old were the pumps? you had at least 2 different issues. Stuff happens. Suntechs are good, period. Fuel quality and tank cleanliness is often an issue.
