Numbnutts Posted August 6, 2021 Share Posted August 6, 2021 Looking for some info on the injection pump for my 84 e6 350 4v. The plate says united technologies but after research there was suppose to only be the bosch and ambac pumps for these engines. As far as I can find the United technologies pumps were used on later model trucks and not in the r model. Tried to upload pic but get error.

br549 Posted August 6, 2021 Share Posted August 6, 2021 I think ambac and United technologies owned them, we use to call them american bosch back in the 70's. I seen many united technologies on r model and mh model on the 4 valve,seem like they were on tractors more and robert bosch were more on dump, mixer trucks. When the E-7 engine came out they went with robert bosch only. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/67630-united-technologies-pump-in-84-e6-350-4v/#findComment-478016 Share on other sites More sharing options...
