Default Injector Pump Rebuild

after installing the denny t stage 2 fuel pin the injector pump started to leak.... it wasn't bad but with 190,000 miles its time to rebuild entire pump... its costing me 900. High? low? average?

industrial injection does a stock rebuild for 750. make sure before you get it rebuilt that it isnt just a gasket thats bad. no need to spend 800 bucks on something when the only thing wrong is a 2 dollar gasket. ive also head that the denny t pin will soemtimes cause it to leak because it dumps too much low end fuel

yeah... i figure if the rebuild still leaks i might go will a P pump.. but idk. I've called around to many places an got the same answer for the cause of the leak. since its got that many miles and being stock, that it started leaking cause changing the pin disturbed stuff in the pump

check the vent tube on the rear of the pump
there is an o-ring for the pin that rides on the fuel pin
