Im recently trying to modify my dual walbro setup to a single intank walbro feeding a Bosch 044 inline,and i want to run -10 feed from the tank lid and i dont know what the best way to go about modifying my fuel tank lid to accomidate the -10 line...

i know that i have to weld a -10 bung to the lid but what else must be done??? Does anyone have a writeup on this setup??? or does anyone sell the modified lid already???

Any help will be GREATLY aprreciated!!! thanks in advance!!!

You dont need that big of a line to feed your bosch. Just run a adapter (-6 an male to 12mm x 1.25mm).

I'm using a Walbro 255 going through the stock fuel system into a hardline to -6 adapter to a Bosch 044 with -6 into the fuel rail

-10 would be over kill

You could run 4 bosch pumps on a -10 line. Stick with a -6 line.

i run a -6 too ''

why dont you take a ride to lowcash racing im sure they would be able to give you a few tips and be able to show you a set up

well im just doing what i was told to reach my hp goals... right now im at 690 whp with my dual walbros. now im going to raise it up to 800+ hp. u still think -10 is overkill??

Yeah It's still overkill..... If you still don't feel comfortable with the -6, then just go to a -8 line.. But -10 is still way too much.

I run a single -8 feed line on my car with a pump capable of 2000+hp, so yes, still overkill. Besides that, a walbro/Bosch pump combo won't get you anywhere near 800whp.

Dual walbros in parallel flow a lot more than the walbro/Bosch combo in series.

hmmm, i was just reading on evans-tuning.com that they have reached over 800 with this setup..Not saying u dont know what your talking about just saying that they claim to have success with the setup thats all.

Thank you for your opinions tho.

It's a great setup, no doubt, but not for 800+hp...
