[Vwdiesel] The importance to lining up oil pump gears with markings on ea...

[Bryan Belman]

I was hoping to try and make the Transportersfest outside of Boston this Sunday.  Is it OK to put in 1.6TD 155bar injectors on the 1.9na motor that normally runs 130bar injectors.  The pump is 1.9na.  I do not have an extra set of 130bar injectors at this time.
I was told this should be OK, any comments?

From what I understand, you can not run NA injectors on a TD motor, but it works the other way around.

I would think the NA pump would not build enough pressure to pop the 155bar injectors, but I guess not?
I will not get my 1.9na injectors back until mid next week from Antrim Diesel in PA.
Thanks

I don't know if Andrew is still part of this list but I created this from
some web page I found a while back about a DIY injector nozzle tester.

the tank and put this in one of my other cars and will put a fresh 5 gallons
of fuel back in tank.
