Do l need to have a primer bulb in my fuel line?. I have now replaced 2 in 18 months at @£35 each.
The engine is a Suzuki 175 with fuel injection and started & ran fine without priming after replacing the bulb. I know there is a one-way valve in the bulb.
I can see the point of one if the engine has carbs or has a removable fuel tank.
I’d keep one in line just incase , Running a fuel pump dry on the newer engines is a major No No!
Couple of primes and you’ve peace of mind there’s fuel in the system before you turn the key.

I know some big engines don't have a priming bulb and rely on the low pressure pump to create the vaccume to pull fuel through don't know why running a diaphram pump dry would harm it it's only a only a mechanically pushed membrane off the cam shaft.
Personally I have one fitted just after my Racor Fuel filter/water separator. It’s useful for repriming the system after emptying/changing filters. Fuel from the Forward fuel tank has a bit to travel, low pressure pump probably would pull it through eventually but still wouldn’t like running the pump dry.

Racor do a filter/separator with a built in primer which I installed 2 years ago, far more reliable and a much neater solution.
