dual pump setup ?

I'm using stock fuel pump with valve to switch between two tanks.
one D2 one WVO heated. Into stock dead head fuel line setup.

Over 50k mile since conversion.

I know the stock fuel pump will die after a while due to heat wvo.

Looking to do a dual stock pump setup for a while due to funds.



anyone do this?

do both pumps run at same time?
How do you switch the pressurized fuel?
Seen some setup with check valve to other ports on head are these reliable?

wanna keep it simple


thanks and happy veggin.

I would imagine that running one stock pump strictly on vegetable oil would be less reliable then running one on both veggie and diesel since atleast the diesel can clean it out instead of letting the vegetable oil stay in the pump while the truck isn't running. And usually when running two pumps they are both connected to a relay so that when you turn one off the other turns on.

I tried the single pump for both VO and diesel but the problem is that the pump is going to see over 120+ degrees many times and you are just going to cook your pump. Its going to leave you stranded on the side of the road. It happened to me but luckily I took the advice of people on this forum and carried a spare fuel pump with me from Napa. Bad thing is that the one from Napa lasted all of 300 miles so I ordered a FASS.

anyone do this? I never used two stock pumps for reasons outlined above
do both pumps run at same time? No. Control with a relay- 30AHow do you switch the pressurized fuel?
Seen some setup with check valve to other ports on head are these reliable? This IS the most reloable method
