my 83 ranger has been starting to act like it runs out of fuel? When i take off from my house i can make it maybe 2 miles then it will start bogging down and losing power and eventually die. It will restart but takes a little bit but then will do the same thing, but if i let it set there and idle it will run forever just idling. So to see if it was a fuel issue i put a Mr.gasket diesel fuel pump(part number 12D) in the fuel line and put a needle valve after it to slow the flow down(4-7 psi is what the pump puts out) and now it seems to be all good...i have driven it about 100 miles with the electric pump and it has not died once. Does anyone know if running this electric pump will harm the injector pump, i put the needle valve after it so the electric pump wouldnt try to push to much fuel into the injector pump, but im just wondering if this electric pump will make a different issue after so long

Wayne most likely your fuel filter was starting to plug and the pump pressure over powered the back pressure caused by the plugging filter. Changing the fuel filter on the Ranger is the first thing to do with any engine problem. I keep several spares on hand.

Yep, I was thinking fuel filter, too.

running a boost pump will make your filter housing and the fuel pump/injection pump to leak. as i tried the same thing, to control dual fuel tanks. i now use a solinoid to switch between tanks.
strange you are suffering the same thing i just experienced. i first tried changing the fuel filter. as my oem tank was the one causing the truck to run out of fuel. i switch over to the in bed tank. and the truck would start running smooth again. switch back and i would stall out or idle very slow. i could see that the fuel line was collapsing when using the oem tank. since the fuel filter didn't work, i disconnected the fuel line before the filter. and tried blowing air back to the tank. it finally let air through the line. as i blew the sock filter off the suction tube in the fuel tank. i reprimed the fuel line and then re-hooked up the fuel line. the truck runs great now. some day i will pull the bed and tank. and replace the sock on the suction tube. maybe in my next life..
my truck has over 250,000 miles on it. so the sock filter probably has acumilated a bit of rust and gunk. the inline filter will have to catch everything from now on..

i changed the fuel filter right when it started doing it, hoping maybe it was plugged up, but the one i took off was only on there maybe 5000 miles, i still put the new one on and did not help....tempforce as for the sock on the suction tube ive already had my bed off and both sending units out of each tank and neither had a sock on them...i couldnt imagine anyone else has takin the tanks out since my freinds dad owned it before me since 1987 when it had 43000 miles on it when he bought it???i did blow air threw the line and it seemed to go back into the tank just fine or at least it didnt seem to be struggling to go back....i put a new front fuel tank in shortly after i got the little truck on the road again, only because the original had a huge rust hole towards the top, but the rear tank i just took out and cleaned out as best as i could and neither tank has given me any trouble until now....it does do it on both tanks, but i havent tried putting a tank in the bed to see if it will stay running that way.......but if thats not the issue is there a fuel pump built into the injector pump?? i would imagine there would be in order to "suck" the fuel up from the tanks...but other than this recent issue ive driven it about 10000 miles so far and its been running good...and with the electric pump on there it runs just the same as it was before....but i dont want to have to leave it on there and risk causing a fuel leaks somewhere...

I had a similar issue with mine. It turned out to be the fuel pickup in the tank. A few inches up from the end of the pickup, there was a check-ball and spring to let fuel in the side of the pickup if the end gets plugged. As it turns out, debris got caught up in the spring and plugged both inlets. Mine didn't have a sock in the first place so I just took tubing cutters, cut it off above the check valve, and ran rubber line the whole way. I haven't had any issues since. If you want to check yours, put a "T" and a vacuum gauge in the fuel line right after it comes out of the tank. Run the fuel line into a bucket after your pump. If you get more than a few inches of vacuum after turning on the pump, you have a restriction in your pickup line somewhere. If this checks out o.k., I would check for the system sucking air somewhere.

Easy way to tell if there is a plugged anything is to watch the push primer handle on the fuel filter. It will get sucked down when the engine is running.
This happened to me when some water froze at the bottom of my sediment bowl and blocked the inlet tube.

I recently also went through a similar thing with my truck, an '84 Mazda. In my case, I ended up dropping the tank from underneath (I'd recommend to anyone-pull the bed), only to find a significant amount of FOD in it. There were several 8-10" 'ribbons' of rubber which I had to remove with a set of mechanical fingers. Since I only recently acquired the truck, I have no idea how they got there, but they would periodically be drawn against the fuel pickup in the bottom of the tank, resulting in fuel starvation. Interestingly, there was no fuel sock or strainer whatsoever--I'm inclined to believe that it came from the factory this way.

i keep forgetting that the mazda used a low pressure fuel pump. my ranger only uses the injection pump's / suction fuel pump. i didn't know that the fuel tank pickup used a check valve, as when i had the bed off, i saw a inline check / rollover valve.
the only other suggestion is to try to run the truck with the tank fill cap removed, as the vent will sometimes fail.

I had an 83 Ranger diesel that did the exact same thing. Turned out to be the fuel heater above the intake manifold had a crack in it somewhere and it sucked air in, no fuel leaks though. I by-passed it and it was cured.

My solenoid valve seemed to be culprit for intermitent stalling. Strange as hell why it didn't stall out for good.

sorry havent responded in a few days, been really busy with work....and not to mention its only 10 degrees outside so not very fun to be outside for long....but anyways i havent had time to actually do anything else with the truck, i have just been driving my other one only because as the fuel problems started i saw i had a small leak coming from the bypass hose that goes from the water pump to the head, and then to my surprise my whole fan assembly was very wobbly, so now the water pump needs changed, ill probably do that tomorrow, already got new "reman" one ordered...costed 148 bucks from rockauto....but with the fuel problem i did hear someone else mention before there is some sort of check valve built in the fuel line similar to what you are saying mhuggler...so i will check into that once i get the water pump changed...tempforce so the mazda uses a low pressure fuel pump in the tank?? if they did how much psi does it put it?? only wondering because if it uses one and doesnt leak why will the ranger one end up leaking??...thanks for the answers everyone....also what kind of antifreeze does everyone run in there trucks??? i know the 6.9 and 7.3 idi's had to use a certian type of antifreeze to prevent cavitation, which seems most people use the factory international stuff and if not that CAT antifreeze....im thinking about using the CAT antifreeze...

I use caterpillar extended life coolant (elc) in mine and it works well. The part number for a 1 gallon jug is 101-2844.

i don't know if the mazda uses a pump or not. i was going on what a different member of the site said that owned a mazda. so if i'm wrong. thanks for correcting me...
i just mention that my ford did leak at the primer valve and at the upper portion of the injection pump when i was using a boost pump between the tank and pump... when i removed the boost pumps. most of the leaks quit..
i still had to replace seals afterwards.... i had a extra primer/filter assy. and just replaced it.

I use an electric diaphragm pump from an early carb'd Honda. Puts out 1 - 2 psi and I don't have any leaks from high pressure. I installed it when my IP quit drawing fuel. It would develop an air bubble in the filter which I would have to purge out daily. You can use a higher pressure fuel pump, just "T" the main fuel line to the return line at the IP with a smaller ID hose. Gives the pump ability to free flow (drops pressure) and keeps fuel flowing to the IP. A lower pressure pump is best though.
