3.5L V8 fuel pump
Hi all,

Just a quick question, I have a 1984 3.5L V8 petrol 110. When I put the key in and turn it I need to let the fuel pump prime up a bit before I start it . I can hear a rapid ticking that then goes to a slower ticking. It then almost always starts first time.

When I am stopped at an intersection I can still hear the tick on the fuel pump.

My question is.... is this normal?

Cheers

My v8 is so loud with the free-flow exhuast,I cant hear anything. Laughing It's fuel injected,and can here the pump priming when starting.With the SU carbs the pump was too quiet to here.The ticking may be normal as the pump works fulltime when engine is running. Puma 110 SW

Not sure it helps, but my pump runs whenever the ignition is live but whines, not ticks, and I haven't noticed any change in speed. It's on carbs which is a lower pressure pump than used for EFI. Fully Restored 89 110 CSW V8

Yeah, it's pretty normal. My old Stage 1 V8 used to do exactly the same thing. Fuel pumps of that era operate around what is basically a set of points and the ticking is them making and breaking contact. Darren

THANKS for the feedback, nothing was really wrong but there are no many new noises in this "new" 1984 truck.....

I have the carbs not EFI - I think they are SU (with the two top hat type top cover on the carbs)

Ill just keep putting along....

Cheers
