NITROUS OXIDE ( nos / n2o ) advice forum

Since fitting my pulsoids the car takes ages to start, I have to turn it over for about 5-10seconds every time.

There's no other issues with the car and I'm pretty sure that even though the fuel pump is priming the fuel lines it's just not getting the pressure it needs. e.g. it's what I would expect to happen if there was a leak on the fuel pulsoid.

However the pulsoids have just been refurbed and there's no signs of a leak in any of the joints, or fuel leaking out of the nozzle.

It's like when I turn the engine off maybe air is getting in somewhere and it's allowing the fuel to drain back to the tank.

Any ideas?

Why not disconnect the supply to the pulsoid incase its just a coincidence

I'm gonna try that next, but I need a blanking plug for the T piece in the fuel line, I tried to blank off the fuel pulsiod feed when I sent it off to be refurbed so I could still drive my car, I tried a few ways but nothing held the fuel back at hi pressure. Annoyingly I'll have to wait for the blanking plug to be posted as I can't find any locally

You could probably get a bung from somewhere that sells good ridge brake hoses

Sorry missed this post, you could always leave the Pulsoid connected and just loop one of the outlet pipes from one Pulsoid outlet to the other, to blank both off and then use the 2nd pipe to loop between both Crossfire ports to blank those of.
