Hi all--- The good news is- my engine is going great. Just have a "how-to" type question.
I am running a ford f-350 chassis with a 1-st gen C I installed. I upgraded the fuel pump to a 2-nd gen with the piston.
I just did it simple. Ran a 3/8 copper line from the engine back to the rear fuel tank (and a 5/16 return line)
I got a NAPA fuel strainer that has a screw-off canister and quick drain on the bottom. I installed it just forward of the tank
on the side of the frame forward of the rear wheel. Everything seems to be working fine.
However---- If I want to drain the QD or change out the strainer element--- I need a way to do it WITHOUT losing the prime
or letting air in the line. I first inclination was to install a stainless ball valve into the strainer where the fuel line goes out. That would
isolate from strainer to engine--- but Its a downhill slope from the strainer to the tank about 2 feet away. Seems like I would need
something like a manual pump in that side of the line to suck the fuel up from the tank and refill the strainer and blow out any air
bubbles before opening up the ball valve on the front side. Are there any small , simple but reliable manual pumps for this purpose ?
Like a better version of a plunger pump from a coleman lantern ----- It would have to be something that represented NO flow
resistance when not being used.......
As an alternative--- do these fancy Airdog type electric pumps have any provision to self prime/purge after a water drain or
filter change ????? and--- if the airdog thing fails--- will the engine fuel pump still suck the fuel to the engine ? Are there any
tangible benefits from an airdog type pump ?
(my power is only turned up very slightly--- still using the stock smallest injectors for MPG)
Aircraft engine use little piston pump primers that work like the colemon type. better quality ---
How do yall do water/filter dumps and not get air in the lines.........
Thanks ahead of time
