fuel pump(s) for hx35

[richard33]

My new setup will be 1600ccs, dsmlink, hx35, e85, built motor/head and a lot of boost. As of now, I have a single walbro 255 but I dont think that will be enough for the 30+ lbs of boost I want to run. Dual walbros is an option but I would rather have a single pump. Any other options?

Bosch 044

So keep the walbro in tank and get a bosch inline? Is that enough? I dont want running out of fuel hold me back from making power so I rather buy something that will definitely be enough

a walboro can be had for under 100 bucks and the bosch 044 is around 200. just run a walboro in the tank and one in the line. that will give you enough for just about anything you will ever do to your car.

If you're trying to save $$, run a dual intank setup. Just pipe them together with a "Y" fitting and call it a day.

^^^Does That Really Work? If So It's A Big Option Instead Of A Full Blown.

That will work well for a 1g, which has much more room to make the dual intank work. A 2g on the other hand is a different story, it has much more limited space from the top to the bottom which is why you see many more 1g guys doing this, and not as many 2g's. Although I believe it's possible to do with a 2g with more modification to the hanger, etc.

I would just pick up a bosch 044 and run it inline, should be good for 600hp on e85.

My single rewired 255 supported 32psi with 1000cc. I would add a bosch or boost a pump if needed.

 

[richard33]

Thanks guys Im not concerned about the cheapest way, just the fact that it will work. It seems like the bosch in line will work and is the best thing to do right now. What about the fuel lines? Do I need to swap out the stock ones or does it matter..

 

[cjridert1]

Probably have to switch your feed lines to work with the inline pump (AN fittings and whatnot). Anyone know if you can use -6 pushlock fittings on the stock feedline? This could maybe be an option, then again if you have the $$ -6AN SS lines will be fine.

Single rewired wally HP 255 is fine for an hx35 running gasoline. 60lb/min is about the limit of the higher flowing compressor. The intank has done that more than a few times. For extra insurance add the inline. Series setups really can take alot of boost (total fuel pressure) and your overall flow goes up as well. . .

Quick question, are you using a HOBBS switch to activate the second pump? Thank you.

Na. Im going to let them both sing and just get a higher amperage relay. Im sure either is fine; the mustangs come stock with a dual intank and they both are always on (as I unerstand it), seems like less variables keeping both running. Hypothetically, if mine fails, I dont have any fuel, rather than if the hobbs failed, Id end up running lean under load.

I'm using the Hobbs switch to trigger the second pump but you can also use the nitrous control on DSMLink too. They are both reliable setups to do the triggering as long you to configure the two relays right. It'll also prevent wear on the second pump when it isn't needed, reduces current draw from the electrical system and help prevent fuel-pressure overrunning at idle.

not with e85 and a lot of boost

That is awesome. Thanks for the heads up. I hope that feature will be available in the ECM link as well. Thanks again and hope I didn't hijack anything.

I didn't see you're running e85
