build update!!!
as im waiting for my ecu to get back from ecmlink for an inspection and repairs if needed, i decided to get started on and almost finish the fuel system.
the fuel cell, has a -8 and -10 feed on the bottom and a -10 return on top, with a -8 breather valve with check ball.
with help from other dsm members on this site (not in person) @ForceFedRed @motomattx @biglady112 @bling5tatus @jimsgsx i was able to set up my mechanical fuel pump with a prime system, and also with some of my own garage ingenuity
-a description of how this works.
starting from fuel cell to pump to rail to fuel pressure regulator back to fuel cell.
main line, -10an out from fuel cell into a one way check valve, connected onto the check valve is a -10an fitting with a 1/8"npt hole.
prime line (for ease of starting), -8an out from fuel cell, to a 100micron filter, then to the walbro 190 inline pump, out from pump the line connects into the -10an fitting with the 1/8npt hole thats in front of the check valve. when this pump is turned on the fuel will fill the main -10an PTFE line, and the check valve will stop the fuel from back flow into the tank.
main line after prime system. -10PTFE line out from connector with 1/8" npt hole to another 100 micron filter, then -10an PTFE line straight to mechanical pump. from mechanical pump into a 10 micron fuel filter (above the fuel rail), then into the fuel rail, from the fuel rail into an aeromotive extreme flow fuel pressure regulator pt. #13132, the out from the fuel pressure regulator a -10an push lock line for the return back to the tank. and the cycle continues
pump mount. 1" square tube welded directly to the motor mount. why? because the pump has to move with the motor or the belt will come off.
i purchased a pully of the same tooth and the same hole size as the bolt for the cam gear. this was done for ease of centering. i then drilled a hole in the back of that gear and a hole in the cam gear in the same location and inserted a cut off piece of an Allen-key, this works as a dowel pin and will assist the rotation of the pump gear.
any questions please comment or message me. here are some pics of the set up so far.
@Bizarre here is a better write up for you.
