I'd look hard and double check for any leaks in the system before writing off the booster, but it wouldn't surprise me if that was the case...
What was the reason in replacing it in the first place? leaking?

Can someone tell me what the ideal inlet fuel pressure is for the DB pumps?
I know the DS likes 8-9psi at idle, which is what I've been running, I just want to make sure that it isn't too much. I tried searching with no luck.
Thank you
Nick
I know this may seem like a stupid question, but I'm assuming you have already verified that all the glow plugs are good and getting power correct? If these are cold start symptoms, that would be my first look.
Prior to my last IP taking a dump, it was intermittently doing exactly what you...
Any reason why you want to replace the injectors? I think a lot of people replace injectors when it really isn't necessary.
Personally I would pull them and have them tested to check the pop pressures and spray pattern. I've only replaced one set over the years, and even in that case I could...
Let me know if you need a parts donor or another to rebuild for a spare. Ive got a couple dead FRB5's and a 10. Personally had horrible luck with all of them so I switched to the Raptor which I should have done a long time ago.

It's alive! Finished up everything yesterday and was even able to get out for a quick road test!
For the throttle cable bushing I ended up using a door pin bushing from a Ford truck that was almost the perfect size. Only had to slightly up-size the inside diameter.
The wiring was much easier...
Got to spend a bit more time on the truck this morning. Installed the new water pump and cover, alternator, thermostats, and brand new IP hard lines from Leroy. I'm now onto my least favorite subject. Electrical. Anyone converted a OBDII truck have any pointers? Bobbie Martin's guide explains...
I had a hell of a time locating an OEM cable. New and aftermarket was not an option. I had even ordered a cable for a 6.2 out of desperation hoping to adapt it if needed. I don't usually consider myself a lucky person, but a stop at the pick and pull junkyard proved otherwise. Found a '93 6.5...
I had seen what Leroy did by rotating the housing, but then id have to re-route the upper hose (that i already purchased new) and possibly the upper intake. I ended up making my own bracket to utilize the upper hose and housing as-is.
The three brackets pictured above are as follows from...
Currently have the new pump mounted in the truck. Resealed the valve covers, new glow plugs, front main seal, fluidampr and pulley installed.
Trying to come up with a throttle bracket design that will work around the dual thermostat housing has proven to be a little bit of a challenge. I...
My DS4 gave up again after 45k miles/10 years. Not a bad run I guess, but with dreams of never replacing another PMD I decided to go the mechanical route. I've had great luck with our DB2 6.2s and was never let down by their reliability.
Started amassing parts a few weeks back and finally have...
Thanks for the replies. Should be able to sleep a little easier now!
I've finally started on reassembly today with my DB2 conversion and this held me up a bit.
I will say this, for anyone building their own install tool, use a high quality throw out bearing or something of that nature. I...
Finally getting around to installing the Fluidampr I purchased from leroy 4 years ago.....
First off, I can't comprehend how anyone could have possibly installed one of these with a mallet as stated on some of the forums. I built an install tool with an old crank bolt and holy s**t did it take...
Yes, the crank position sensor. I have a manual transmission so I'm not worried about the transmission inputs.
But since you mentioned RPM's.....does the tach receive signal from the CPS or the alternator? I wouldn't want to lose that function.
-Nick
Can anyone tell me if the CPS serves any purpose after this conversion? I know the cold advance for the pump is run via the HPCA, but is the CPS still used for the glow plug circuit? Thinking I might just replace it while I'm in here as it is so easy to get to now.
Also, if I were to find a...
@GM Guy I know where you head is at with the DS4 (in good operating condition). I will miss the ability to have my on demand high idle switch. Although the DB2 is able with the solenoid, the ability to fit it in there with the bracket is probably not too easy. Other than that, I can do without...
Thank you for the offer, but the earlier posted pictures answered every question I had in regards to clearances and part numbers. Keep that "rare" crossover for your next DB2 build!
-Nick
Since starting this post I was able to find quite a few pictures of modified brackets over on the other place. Seemed the best place to look was those "upgrading" to a dual thermostat housing with the factory '93 DB2.
I have since decided to keep my dual stat housing for a couple of reasons...
Thank you deejaa!!
Exactly what I was looking for! and that verifies the part number too.
Hard to tell how much room I would actually gain for the throttle bracket. Seems to me the upper hose outlet would be the limiting factor on both the single and dual housings. I'm still going to try and...
