Belt driven fuel pumps
So guys , educate me on this please ! I've been reading thread after thread on fuel pump set ups using dual wahlboro pumps ,return lines ,and so on . Would it be just as easy or even easier to run a belt driven fp ? I understand they run return lines and big regulators too but idk ....they sound like they'd get it done nicely . Tell me the pros and cons . Thanks

Con: the guy at Aeromotive told me that I was going to boil the fuel on a street vehicle because it runs all of the time, as opposed to extra electric pumps that can be turned on as needed, with a Hobbs switch or other ways.

Curious on this topic myself, as multiple fuel pumps become necessary and cumbersome with E85. Two walbro 450s running simultaneously pulls a huge amount of current, could only imagine 3. |
Walbro450s at 80psi pull something like 25amp each, thats pretty impressive. If I needed more than 2 walbro450s I would do a mechanical pump. Very much doubt you would boil the fuel. Electric pumps run all the time as well.

There are some smaller belt driven pumps out there, so even if you're not trying to build a 5000 hp daily driver, you can find something to work.
The biggest complaint with multiple electric pumps is that if one or two fails, the motor will/can burn up. With one pump (whether it is electric/mechanical), if it goes bad the engine just stops running. I had twin Magnafuel 4303's on my last set up. Ran both all the time, but it's not a street truck. Never had delivery issues once I put the right regulator on it. |
Well it's not that I want go crazy with the hp but I'm just trying to figure out my options if or when the flex fuel pump is topped out . The way I understand mid to upper 500 hp range is about the limit. Keep in mind I've done nothing to my truck yet so I'm just putting together some plans . And putting money back !lol. I was gonna start buying parts but I figure if anything ever happened to the truck ....god forbid.. I'd have a bunch of parts to sell or store .
Yeah, I like the idea of one pump if it's possible. Not only that , if I could set it up not to have to worry about keeping the tank 1/4 full or more would be nice . But I'm sure if it was so easy someone would have done it already .. right ? Lol . |
there's no good reason to do a belt pump with that low of hp

If yiu do it right you dont have to keep a 1/4 tank. I have dual pumps and i run my gas down until the low fuel level light comes on. It has been setup this way for 6+ years and i have never had a problem. People that hack up the fuel buckets have issues.

More than likely your truck isn't fast enough to have problems.
