I have looked in the archives for this subject and couldn't find it. Now the question what size fuel pump should I install ie how many gallons per min? Is there even a standard to this. My 1989 Eagle NJT has a diagram for the placement of a priming pump. Or should I say that one was there before I got the bus and most likely removed by NJT. So should I just install a pump inline or try to reinstall the priming pump back in place. Replacing the priming pump to me doesn's slove the problem or does it. Someday my bus will be finished and I promise I will stop asking so many questions but as always guys thanks Tony | ||

most buses don't have them,have no idea where yours was,or if it had one, get back close to the fuel tank & put one in the line & run a 12 volt wire to a switch,so you can use it when you need to fill the lines with fuel,just a small elec. pump will do,the one at advanced auto parts (used to be Western auto)can be had for about 30.00 | ||

Ahoy, On my -01 Eagle, I incorporated a check valve in the fuel line from the tank. (The check valve may have been on the Eagle, or from a GM4106). Any truck supply house will have an acceptable item. I then connected my fuel pump acros this check valve. Inlet on the tank side, discharge on the engine side. That way, you don't have any potential restriction from (possibly) too small a pump. Work fine. I can't imagine being without such an easy and simple system to use when you change filters. Some of the flails and horror stories of those who try to get along without a booster go well beyond entertaining | ||

Bob, I really like the idea of the check valve in parallel with the primer pump. Although I did not think to do that when I installed my primer pump I certainly would have if I had thought of it. Great idea. Richard | ||

Here is how I did mine. I used a ball valve instead of the DD check valve just because it was available and MUCH less expensive. The wires are disconnected because I had "borrowed" the pump for another project and I'm just now re-installing it.   | ||

A simpler version is to plumb a Scrader fitting or similar after the stock check valve and just get a SS pump up fire extinguisher. The 2 gal or so will prime most any diesel , and has the advantage that it can be used to find air leaks. Pressurize and watch for drips. FAST FRED | ||

Good idea FF. Would a regular garden/yard sprayer work? I think the electric pump would work as well to find any air leak as long as the system is under pressure. If you use the fire extinguisher idea, do not forget to always keep it full of fuel and always carry it with you. Richard | ||

Would a regular garden/yard sprayer work? IF diesel doesnt disolve it ? I think the electric pump would work as well to find any air leak as long as the system is under pressure. DA Book requires about 60 psi to find leaking jumper tubing. EZ with a SS pump up can, can harder with most auto pumps. FAST FRED | ||

Hello. I use the metal garden sprayer, no ill effects on its day job as yet! When I run out of things to do, Len's system is the way I'll do it. If I can't remember to manipulate that ball valve, then the Alzheimer's is getting too bad to drive, best I lose the prime and can't remember how to get it running again! Remember, we really don't want to make it that idiot proof!!! happy coaching! buswarrior |
