As far as I know the Mazda and Ford never had inline pumps. The injector pump drew the fuel from the tank. The Mazda B2000 had an electric pump on the frame though for gas models. Also, the check valves are under the hand primer assy. remove the assy and spin the filter off and you will see them. If your injector pump stopped pumping fuel from the tank it was because your check valve in the primer housing was bad and the fuel would syphon back to the tank when you shut the truck down not a faulty pump. If the check valves are good, lines are clear, and filter good you should NOT need an additional fuel pump in the line! If you do somethings wrong and needs looking into. Also check your water seperator on the frame, maybe corroded and has a pinhole???

i know it shouldnt need the pump, but its not a problem of it not starting after its shut off, just driving down the road it wants to die after a few miles, even if i turn the pump on run it for about 2 miles then shut the pump off, in about 2 more miles itll run out fuel again but if i flip the pump back in itll pick right back up and be ok, the spare motor in my barn is the original out of the truck and it had that problem so i figured it was maybe the ip or because the motor had alot of either sprayed down it from previous owner so im sure that didnt help anything for it so then i put the other motor from the junk truck(it ran and started fine ALL the time, couldnt drive it thought because it had no rear axle or basicly any back half of the truck) in the truck only for it to do the same exact thing....so i dont see why both of the check valves in filter housing would be bad? ...the water/fuel seporator i cant get the handle behind the seat to move, but i havent done much else with it to make it move or looked for any air leaks, but it doesnt leak any fuel...i thought about swapping the seporators, or is there anyway i can remove it as i dont see the other one pulling to easy either?

Ok, mazdadieselrool, to tell someone that the "only problem" is this or that, or the "only fix" is this, is usually wrong. Yes, if everything is working as it should, there should be no reason for a pump, but it's not working as it should. Many people have commented that they have a simular problem, but different fixes. That's the point of the forum. Share your stories, problems, and fixes. But don't be a know it all.
My IP lift pump is bad! I had it tested. It failed. Completely. So, do you think that my IP is the only one like this or could do this? No. Didn't think so (infact my friends VW IP lift pump just failed the other day, so we replaced the IP. Works like a top now). I shared my story in hopes that others can benefit from it. It's not going to be the fix-all for everyone.

fatguppy first off until youve bought a B2200 brand new back in 1982-84 then drove it 579,000 miles over 15 years you can talk smack to me. You were prob driving 1980 Camaros back then. Until then zip it! Im not a know it all I was offering advice. Ive just been driving these since 1983! How did you determine your lift pump was bad in YOUR pump? He stated the old engine in his truck did the SAME THING. Now the new engine in the parts truck ran fine UNTIL HE INSTALLED IT IN HIS GOOD TRUCK. HELLLLLOOOO. What does that tell you? Its NOT the pump its in the lines somewhere! My Ranger had a bad fuel heater and I bypassed it and it was cured. You have a problem from the tank to the pump with air getting in the lines or check valves being bad and they DO go bad at times. Dont believe me? Remove the filter housing and spin the filter off and inspect them. They are tiny metal reed types. If they are OK check all your lines and hoses or swap the fliter housing from the junk truck to your good one and test it. FWIW Ive heard all the stories of pumps going bad on these but have never seen just the lift pump going bad, either the throttle shaft o ring leaks or the pump gets destroyed from water in fuel. The breather mod I have never done on either B2200 I have owned and havent had oil issues ever. Ive heard of floating valves on these but have revved the hell out of both of mine on the pike each time I drove them and never had an issue. Its a bullet proof engine with few issues.

Nope, never had a camero. Never wanted one. And nope, never drove a new b2200/ranger diesel. But I have driven my 1983 diesel for the last 20+ years and +300k miles. Rebuilt 4 of these engines, done 6 perkins 4.134/s2 engine swaps into rangers and mazda's. So I've done a little work to them! I agree that these engines are great. I wasn't talking smack. You were quite sure in your diagnosis, yet you hadn't seen the truck, just heard about it. I have no problem with advice. That's what this forum is for. Just please temper it so that it comes across as advice and a possibility, not fact. I'm sure you've experienced quite a bit with these engines/trucks and we would probably all benefit from that experience. But just because you havent seen a falure of a certain type, doesn't make it not so! My IP lift pump was drawing less than 0.5 inches of vacuum while running. This was tested right at the pump inlet. So I'd say it failed, especially since my '84 pulls 7 inches of vacuum. My friends VW - 0.0 inches of vacuum. Same style of pump - Bosch VE. So they can fail. This is the first one I've had that failed this way. I had one pump shaft shear in half this last year! It was a high mileage pump and I'm sure there was damage from water and junk in the fuel from the previous owner. I had bought the truck 4 months prior and it was pretty neglected. I'm sorry you got your feelings hurt. I wasn't that hard on you really! I can be much more of a bear sometimes, just ask my wife! But I'll try to keep my comments a little nicer from now on!

ill take everyones advice given, the first thing ill do is bypass the fuel heater as its easiest(i did forget to mention i did reuse the fuel heater off the original motor and put it on the motor in the truck only because the plug in broke off on the one that was on it)....its still to cold here to do much of anything, even in the garage because id have to put it in there a day early and let all the snow and ice melt off it before id work on it...i hate working on stuff when getting dripped on by everything....so ill probably just continue to use pump till its nice out then figure out whats wrong...i work 6 days a week now so really dont have time to do much until then....thanks for all the advice, when i get around to fixing it, ill be coming back and re-reading it all to check every thing out on it to make sure i didnt miss anything

Wayne; I've had a boost pump on my Mazda for years, and would like to point out that it does no harm if the pressure is low. Mine was originally intended just to help push vegetable oil from the heated tank in the bed up to the engine. Mine also has a fuel pressure/suction gage, so I highly recommend. The gage is tapped into the fuel line just before the IP. It should never indicate more than 8 inches Hg suction, which would otherwise indicate a clogged filter or other restriction. By your description, the filter is clogging and can't quite keep up with the fuel demand. Then again, if you've changed filters and it is still happening, then it is more likely something else, such as a clog somewhere else, or an air leak. An air leak will make itself known when the pump is used - you'll find fuel leaking out somewhere, since most leaks work both ways. I had a problem with my Ranger shortly after buying it. The water trap drain valve was stuck and took some work to free up. It then drained about a cup of dirty water. The vehicle had sat for a few years before I bought it, so that might have been condensation. I can imagine the trap getting clogged and causing a restriction, although I've never experienced that particular problem. The Mazda fuel pickup inside the tank is just an open tube, but I don't knon what the Ford has. Can someone tell us if the Ford uses a screen inside the tank that might be clogged?

the ranger is just an open tube as well, at least mine is for sure...ive already had both sending units out so i could fix the fuel gauges...and to replace front tank...i would like to drain the water seperator but cant get the handle to budge but i also havent tried to hard but that will be on my list for sure too...there is the few hoses that go onto the seperator that i havent changed yet but all the steel lines look rusted too, so maybe ill just run all new fuel line in the summer...my truck sat in my friends yard for about 2 years, then behind my barn for about 7 years....and other truck i got sat in my neighbors field for 4 years just up the road and i never even seen it there before. the one from field popped right off with a pop bottle of diesel on the the fuel supply line and ran good, my friends old one they used ALOT of either on it and it was addicted really bad, it would NEVER start without either anymore, so that motor is now sitting in my barn as a parts motor if i ever need any

Wow looks like I found a great place new owner of a 84 Ranger 2.2 perkins. Its has an elect fuel pump on the frame next to the water separator that someone disconnected. Last owner said it won't stay running without it. I'm going to shut it off and see what happens. I'm sure I should get the fuel running back thru the separator agian.. More to follow and thanks for any advice
