others will say you need an electric pump, i disagree.

Others will say for the same money you can install an electric pump that will do the same job with less physical effort.

I have one of the old hand pumps with the DD emblems I never knew you leave one in line like on the CAT and Mack engines that were mounted to pump we just used ours on the DD to prime then removed it

That is how I found the rotted fuel lines . I added an inline fuel pump from napa . Previously I would fill the filters and she ran for short time but never spilling diesel well the inline pump showed me ! And now the pump stays put so if ever ran out of fuel well you all know that.

I have had mine inline ever since i have had my coach. use it every time I change filters, and I use it also to pump it up just to see if I still have prime. If the pump holds pressure I know I'm good.
When (besides here) was the last time you saw an electric pump on a Detroit...
I guess I'm older than old school...

I know they work Donald they do on a Cat,Cummins and Mack I just never saw one left in line on a old DD fwiw DD has always had a electric pump on their marine engines still do even with the newer engines they are used for polishing the fuel also on the marine engines but I don't think the little inline pumps would work for polishing fuel. MCI had a electric pump for some of their buses the hand pump should be fine they have worked for 50 years I know of IMO it is what ever that works for a individual.DD still sells the hand priming kit the last time I checked 400 bucks with case,fitting and hoses, quick disconnect on the hoses and fittings a little pricey IMO

I know that most people would use a pass thru pump, I just don't like the idea of the pump possibly causing a blockage...with the hand pump locked the fuel has to go to the engine...
just my way.
and yup i probably have the only permanently mounted hand pump on a detroit.
regardless I would not leave home without one, at least in my tool box.
