2H leaking diesel @ primer pump. Pump won’t compress down to locked postiton

[TysonFunk]

Just found an issue with my 86 2H. I drove down a logging road to camp last night and just got home now. Saw the litfter/primer pump was leaking diesel. About a drop per minute. It seems the primer pump has sprung up and will not compress down to locked position. I’m afraid I will introduce air into my fuel system if I leave it be. Does anyone know how to compress it? Seems like there’s too much pressure on it.

Pics for help

Thanks in advance!

Its time to replace it.. they are readily available. Find the Bosch unit preferably.

In the meantime.. maybe crack the bleeder nipple on the fuel filter, and see if that will then allow the pump to be pushed back down.

Here’s the link. I have ordered two. The first one looked like what is pictured and the second looks like our original pumps. I prefer the slim design pictured which is on my BJ40. The other is my spare.
Amazon product ASIN B0190VNTZW

Crack the bleed nipple push it down and screw in that will stop the leak until you replace it.

replaced my fuel filter the other day on my 2h and went to prime it and it was spewing fuel till i realized i was a dummy and didnt open the bleeder screw. after opening it stopped leaking fuel. is the fact that it leaked at all a bad sign or was that just because i was trying to pump it while the system was closed? doesnt leak otherwise once closed.

It shouldn't leak when open. They are cheap and easily replaced!

might keep my eye out then for a the metal one i saw earlier in this thread. the plastic one doesnt instil confidence hahaha. pretty sure my leakin g was due to trying to pump wihile the nipple was closed. but sill change regardless thanks

It would be the extra pressure there since the bleed screw wasnt open, that would show the the internal seals are not the best and your hand primer should be replaced. it may draw in air if not.
