I put new bushings in the bar-ends on my parallel 4-bar rear suspension recently...ordered extras so that I could carry a few in the toolbox, too. I know they aren't a usual "failure" risk, but they were SO hard to find that I got extras so that I would not be held up looking for repair parts should one of them fail in the future.
Good question....outa be a thread on the forum for this issue!

Now you made me curios - how many miles you drive a year?

I've had a Holley black pump in my SPF. for around 6 years and 40k miles. No problem. Reason why? I use a Mallory return style regulator and use a relay system on the voltage supply. No excessive load on pump with a dead-head regulator and 100% of voltage needed to keep from having high amperage pull due to low voltage. After a long drive, pump is still cool to the touch. Makes all the difference.

Most pumps fail due to low fuel levels, as it is the fuel that keeps the pump cool.

Very simple...

Fuel Coolers at Flex-a-lite Consolidated





...less than $50.

Important especially on return style setups.

Why on "return style setups?" I thought they had the advantage because the fuel would not heat soak so much in the engine compartment.

I set up my Holley Blue pump seven years ago like Eric. Painless relay and a Moroso return style fuel log/regulator. Runs like a champ. I believe running a deadhead style regulator on the street is asking for trouble. Excess fuel must be plumbed back to the tank to prevent cavitation and heat buildup in the pump housing. Also a poor mounting location (too high) and restrictive inlet and outlet fittings will assure a short pump life. These are basics to any good fuel system but when they get ignored then the pump gets blamed. I've run Holley pumps for 30 years without one issue ever.

It's not about the engine compartment, it is how many times the fuel passes through the fuel pump - the fuel pump is the reason for the heat.
