bad idea to do it this way?



this would make it much simpler. no need to cut/weld or modify the stock fuel pump assembly at all. except for mounting the 2nd fuel pump.



so basically all i would be doing is adding a second walbro, then Y it off to the stock outlet the original fuel pump is connected to.

double the possibility of failing go with a single large pump

i dont want to have the sump and all that. and even then, that one could fail and theres no fuel. if one of the walbros fail, and the others working my chances are better to save the engine...



plus, theres more people running dual walbros than a single large pump. even then they use a walbro to feed the larger pump. so you still end up with the same thing in a different form.

cobras run dual pumps from the factory... I dont see a problem, now the good question is do you really need two fuel pumps?

For the 10AE ?

sen2two

nah, for my black one. i thought about adding dual walbros to her and having it retuned whan gabby skern was in orlando a little while back. but decided shes fine the way she is.



and yes, i will be needing 2 walbros. looking to make 600+ with the garrett 1.10 i have on there. and it only has a .86 rear

pushing two into one line would mean having to use a bigger single line otherwise the increased volume capacity would be wasted, altho i guess you wouldn't see pressure fall as easily.



doing it that way basically makes the size of the fuel line your determining factor, if you start having fuel starvation issues youd need to replace all the line to a bigger one, whereas two individual lines guarantees enough fuel flow.



as far as "twice as many things to go bad" i can count on one hand the number of times ive seen a walbro suffer an issue not caused by the user.

ive only seen one walbro fail. not to worried about it...



i agree with needing a bigger fuel line. so on yours, did you run 2 feeds all the way up? as in, one pump per fuel rail, and then join the return with a Y fitting?

I thought of that today, but then you will need two regulators, and the return line will need to be pretty good sized.

Im pretty sure kev ran a line to each rail from each pump and only used one regulator. I did the same but I had to y off after the pump. ive personally seen 3 walbros fail at seperate occasions, and your return line should not be larger then -6 i believe.
