After just a year and a half (and 20k miles) of installing a set of Python remanufacured fuel injectors in my 88 T2, the primaries are leaking again.

I run premium fuel, and I throw a bottle of fuel injector cleaner in the tank every time I change the oil.

Is this typical of Python, or did I just get a bad set? Should I just get another set of them, or should I blow big bucks on a NEW set?

Thanks

 

This will bump you back to the top. But how do you know they are leaking? Visual? Primaries and secondaries? Only one? Several? How much were these rebuilt ones compared to the *big bucks* ones. TO THE TOP NOW.

 

Can't say ive known python to be great quality but could it just be bad o rings? Try that to see if it fixes the problem and then see if you need to buy the "big bucks" ones

 

I pulled them over the weekend to see what was going on. The Secondaries are fine. Its both the primaries that are leaking again. One primary more than the other one, but both primiaries are leaking. I took them over to a shop that has an ultrasonic injector cleaner, but they still leaked after cleaning.

I picked them up a year and a half ago for $40 each. They had a 12 month warranty at the time, which really sucks because now Python offers a lifetime warranty on them, but mine don't count because I bought them before the warranty policy changed.

So of course I have to either buy another set of rebuilts from them, or shell out $125 a piece for new ones (I think I saw someone who had them for $125, it might have been more, I'll have to double check).


No, I'm talking about injectors leaking past the pintle and into the engine, not external fuel leakage like bad o-rings etc. This is the problem that causes engines to flood and not start when they are hot. Glad to hear that you have had good luck with Python injectors though.
