Hans Remmers Posted March 27, 2022 Share Posted March 27, 2022 The transfer pump or the injection pump? Transfer pumps should still be available through a PAI vendor. There are different pumps based on injection pump manufacturer and hp rating.

PJS truck Posted March 27, 2022 Author Share Posted March 27, 2022 The supply pump is bad engine is E6 350 4valve and pump is no longer available Quote Link to comment https://www.bigmacktrucks.com/topic/69441-e6-350-4valve-fuel-supply-pump/#findComment-493457 Share on other sites More sharing options...
Hans Remmers Posted March 27, 2022 Share Posted March 27, 2022 Depending on the year there are at least 2 completely different options for that and they did not interchange. The Ambac and Robert Bosch used totally different pumps. There should be an aftermarket new available through PAI or another manufacturer still. I have a used for a Robert Bosch. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69441-e6-350-4valve-fuel-supply-pump/#findComment-493459 Share on other sites More sharing options...
63BMack Posted March 27, 2022 Share Posted March 27, 2022 The diesel and injection place I had my pump rebuilt. rebuilt my suppy pump too, don't know why it can't be rebuilt unless he has the tachometer drive supply pump. Did Mack quit using the tach drive pump on the e6 4 valve.

Vladislav Posted March 27, 2022 Share Posted March 27, 2022 As said above PAI offers supply pumps for that engine. Units put onto Ambac and Bosch injection pumps differ. But even that seems being possle to climb up with some re-machining or use of adapting parts. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/69441-e6-350-4valve-fuel-supply-pump/#findComment-493474 Share on other sites More sharing options...
Joey Mack Posted March 27, 2022 Share Posted March 27, 2022 the last 2 RW's I worked on had E-6 4Valve engines, with Ambach pumps, lift pump did not have a primer, and the tach cable was going into the top of aux. drive shaft housing, driven off the aux. drive shaft.... jojo Quote Link to comment https://www.bigmacktrucks.com/topic/69441-e6-350-4valve-fuel-supply-pump/#findComment-493481 Share on other sites More sharing options...
Vladislav Posted March 27, 2022 Share Posted March 27, 2022 To me it looks like you can install a primer pump just in place of the 2nd plug. Or better to say that spot supposed to suit the primer but Mack "simplified" the things for a operator at a certain time to not bother his mind with such a unnecessory item as a primer. And plugged the 2nd hole.
