Hi,
I changed the Diesel filter on my '92 Bighorn LWB with 4JG2 engine.
While bleeding the system, the hand pump gave up and started sucking air.
So I bought another used primer, but ran into the same problem.
I guess, there's a kind of sealing in the pump what gives up over the years?

Before I buy another filter housing with the same problem, it's probably more reliable to replace the old primer with a new part.
If possible, I would prefer a solution as close to the original as possible.

What do you recommend?

Cheers,
Thomas
