fuel pump INOP
I installed a walbro 392 pump a year ago and it appears dead. I have been running B99 BioDiesel for about 4000 miles. the truck will start and idle rough.
pump has 12v. makes no noise. 2 pressure gauges say 0 psi. I get no fuel from the drain when opened and engine running.
anyone else had problems with the 392 and Bio?

Can't comment on the Walbro, but haven't had any issue with the stock and B20-B99 for about 5500 miles now or so. Here is a bump, maybe someone can give you there .02.

Isn't there a Carter pump that can be picked up for "cheap" at an AutoZone or something? Like $100-ish I think?
EDIT: Have a look at THIS THREAD. Maybe if you reach out to Clay he'll be able to give you the Bosch part#.

My 392 only lasted a few months when I installed it last fall. I'm running regular diesel and not bio. I ended up installing some pump I got from O'Reilleys. Paid around $150 for it. So far so good....

Thats a decent price on the Bosch from the dealer. I went with a Airtex (I think) from Auto Zone for 142 bucks and its working fine.
Youd be paying right around 350 shipped from Ed and would have to wait on it.

First, you drain the fuel bowl. Then you lay directly under the pump. Then you use your special little tool to disconnect the quick-connect fitting. Then you lay there while all the fuel in the feed line from the pump to the bowl runs down your arm to your chest making you squirm out from under the truck.

Don't forget doing so in a down pour on a truck too tall to fit in the garage...
found the 'other' set of quick connect tools. Not sure if B99 is better or worse running into your armpit.
got the new pump in, took awhile to get the air out. had to drive around the block a few times.

Man, Went to the shop yesterday to get new Sneakers put on the jeep. My buddy told me that he had to 7.3's in this week. Said one was fuel pump and the other was ICP sensor. And with recent events with these two on here lately. I am thinking now of picking up one of each to toss under seat. I travel with the camper and hate breaking down and locating parts.. Waterpump,ICP,and fuel pump. Under my seat? Overkill huh. But then i will never have anyone of those fail seeing i will have a spair.
