  • Fuel Pump, rebuildor replace......

    Car died while out for a drive......was pretty low on fuel, but not empty......primed fuel pump manually, car started and ran for a minute and died......no fuel coming out of line to carbs....repearted manual prime a few times with same effect....coud hear fuel gurgling in carbs until they ran dry.....any opinions on rebuild vs replace? BTW the pump is not OEM, but a “new” one, from either Moss or TRF. I have an original, but decided to go with the “new” when I rebuilt the engine. Thanks as always for the feedback!

    I rebuilt mine, a lot better quality than what's available new. But first check for plugging since you were at the bottom of the tank.

    A word of advice, if you are going to, or have installed a "new" aftermarket fuel pump, save the metallic filter screen from the OE pump, it should install in the aftermarket pump. All aftermarket pumps come with a plastic screen that distorts badly and are ineffective as a filter.

      Could your fuel filter be clogged?

        Was wondering and will check and replace just to be sure....sort of assumed that if filter was clogged, it wouldn’t prime, but that’s why I’m asking! TY!

      +1 on that. Generally, if the priming lever will pump fuel, the pump and its diaphragms are OK - there's some other fuel-related restriction.

      Also, there is a short piece of rubber fuel line from the bottom of the tank that takes a 90 and goes to the steel fuel line under the car. Seen these clogged, just cut off and stick a new piece of rubber fuel line in.

      One of HG's recommendations in these situations is to lift the fuel filler cap when the car stumbles and see if the problem goes away. That means somewhere in the vent line there is blockage. You can also open the filler cap after running the car and see if you hear a "woosh". Same issue - clogged vent.

      Alternatively, drive with the filler cap loose (unlatched) or open to see if the problem disappears. It's a common issue with the TR6. So often, in fact, that in my case I fashioned a little piece of gasket material purchased from Ace Hardware to allow the cap to close but not seal. See the picture below.

          Stopped by Then and Now Automotive today. Lisa, the GM, has been there for 28 years. Her knowledge is surpassed only by her customer service. One look at my fuel pump, and she reappeared with a rebuild kit in 30 seconds, All rebuild kits are 100% made in, USA, mostly in the shop next door. Hit her up, she’s incredible!

            I used Then and Now’s rebuild kit and it went perfectly! Glad to see the face behind the products.
