That is the one.
To fit it, you will need to remove both fuel lines going to the lift pump, but even then you may not be avble to get a good grip on the new one, to tighten it up.
In that case I recommend removing the lift pump fron the IP and tighten the primer plunger before reinstalling the lift pump and hoses.
Priming is a breeze with the new primer. - Much Cleaner too, and my hands don't smell like fuel.
