    Cool Fuel-pump

    Where to mount fuel pump mk4 3 link suspension. Any suggestions as to what works best. Here is the pump I'm considering if that helps. Any recommendations are appreciated thanks.

    Some use an external pump. But an in-tank fuel pump is more common and has advantages aside from not having to find a place to mount. An in-tank pump is quieter and runs cooler. Something to consider.

    I ran an external pump on my first car and mounted it under the passenger side seat pan. It drove me absolutely nuts. Under 40mph all I could hear was it loudly droning. After less than 2 months on the road I bit the bullet and retrofitted an in tank pump. Game changer.

    I'd be going for something with better "broke-down-on-the-side-of-the-road-in-the-middle-of-nowhere" availability like a Walbro GSL392BX.

    Could you give me some details as how you accomplished this. Because now the hanger that comes with the kit won't take a pump and the pumps on summit racing site that includes hanger don't have enough lph to supply my engine. They are only rated at 176 lph my engine needs 300 lph that excludes a 33% cushion

    Cobraman, many of us use the Pro-m hanger and a Walbro 255 or 340 pump. It has 3/8 (6AN) fittings for output(Feed) and return. Check their videos out.

    I used a unit from quantum fuel systems. It’s a little more bang for your buck than the pro M unit. I went with a bigger LPM so I have the option to run a supercharger down the road. Anyhow fits the same. You will have to slightly modify your tank opening however. Not a big deal, lots of folks have done it. I did it the first time with fuel in the tank with snippers and needle nose.

    A 255lph Walbro is more than enough. They are a dime a dozen. Buy a hanger kit that includes the 255 and call it a day.

    I've used this exact setup on four builds. A SBF, two Coyotes, and an LS. Bullet proof. I've seen a couple of builds use this pump from Aeromotive. Seems like a decent option. I've used their regulators and have always been impressed with their quality. https://aeromotiveinc.com/products/8...YGiYf0-3fE019Z
