bought another dump truck its a 1987 ford L8000 tri axle with a 7.8 ford diesel.But it has what looks like a p7100 pump sorta but there is'nt a afc hausing right on top. any one have any expeirence with these pumps. it does say bocsh on it thanks for the help

 

no one knows anything about this truck.or pump i find that hard to beleive.This forum gets me everytime i post a thread i never get any replies.So thanks anyway

 

Sorry, I can't help with your question on the pump. Maybe a Ford site. Many engines use a Bosch pump and from what I understand there are a few P series designs, I had what appeared to be a Bosch P series on an old Case 680 backhoe. Good luck with your search.

 

post it in the general diesel section on this site, i think more people will see it and respond. I'd help but i'm still getting familiar with my own 12v, lol.

 

It is a Bosch A pump. There is a little bit of power to be had behind the little plate on the back. A 10mm socket and a screwdriver are all you need after you get the plate off. Loosen the locknut and a full turn can yield you as much as 50-60hp. Don't get too greedy though as anything more than a turn and a half won't get you anything more without injectors. Also, look and see if on the back of the pump there are two flat head screws (one big one smaller one) with lock nuts. If you like an idle with a lope then leave them alone. But, if you don't then not adjusting the bigger of the two after adjusting the one under the plate will get you an idle with some serious lope. The smaller one is your max rpm limiting screw. That is if the truck A pumps are like the Ag A pumps. Other than that I have no real clue.

 

tahnks for the info ckt i will check it out as soon as my driver comes in.I hope it is like you say it is.My main problem is the turbo dosent spool up fast enough.There is stud on the back of the pump like the one on my 98 12valve do you no if it will give me quicker boost if i spin that stud in ?

 

depends on where it is located and what stud you are talking about....

 

its on the very back of the pump with a little sheet metal nipple covering it.is this the screw you are talking about adjusting
