Weldon Fuel pump Question
#12
Back in the day (20 years ago) we use to run Weldon on all the big HP cars that we would build. Weldon pumps are rated for aircraft use, that might tell you something. You cant have a fuel pump fail in the sky. I run one of their regulators in the street car. Its dead nuts accurate. Had to replace a diaphragm in the regulator because the alcohol in the fuel cracked the rubber.

Just asking " no issues unless filters get clogged " what filters and if any filters that are getting clogged to restrict fuel flow -- one has possible some major issues with and how any filters become clogged.

Think what he is saying it will burn the motor up on the pump when the filter gets clogged. I have bin there also. Kinsler makes a mega monster filter with a built in check valve huge compared to the smaller filters.

I understand that no matter of the fuel pump. I thought he was having problems with his fuel filters getting clogged and more than once. But maybe he was making general statements about getting filter clogged. But again that holds true for any fuel pump.

They are fantastic pumps, run forever with plenty of volume and pressure, the only ones I found to feed 8 to 1500 hp. We had 1 burn up because of water going through the filter, it swelled up the cellulose element and caused enough restriction to fry the motor. This was NOT a bad pump just an unfortunate situation. The filters were Weldon pre and after filters. They recommended using the Ramco filter / separator, no problem since. I'm sure any pump would have failed under those circumstances.

I totally understand and no matter of anyones engines and fuel pump installed - if one is clogging fuel filters - one has contamination issues hugely of their fuel system. I would address that issue ASAP. Not only will it hurt fuel pumps but cause lean conditions for the engine(s) in short order.
Merc Racing engines use this same FST filter as well. OEM stock install from Merc racing.
Also thanks for the reply and your time posting.
