I think there must be a check valve built into the 3 port djet pump
I believe mine is not working (Hard starting symptoms) Has anyone pulled theirs apart? Pictures or a thread? I'm also wondering if adding an in line check valve would work? |

Ok it's just a bypass
So has anyone ever added a check valve? I imagine it adds some restriction to the system What would be the other reasons this is a bad idea? I'm having a hard start situation If I turn the key it is a 25 second crank before it starts If I turn the key off/on about 5 times and let the pump prime Then it will start instantly So I'm loosing pressure I figure it's either a bad/leaky injector or a situation where the system s draining back to the tank I will test fuel pressure and injectors when I get home But might also test the drain-back by adding a check valve? |
