Intank Fuel Pump Upgrade & Fuel Pressure Regulator - VL RB30 Turbo - Walbro 255

This is my VL running a very conservative "OEM plus" style turbo kit. VL's run 2 fuel pumps, an internal lift pump and an external high pressure pump. I'm upgrading this convoluted 2 pump system and replacing the internal with a Walbro 255 high pressure fuel pump and deleting the external. This should quieten down the noise and provide more than standard fuel flow. Of course an adjustable fuel pressure regulator is on the cards also!
Lastly I will be hacking the inside dash to throw a dirty boost gauge in a shitty location to keep an eye on boost levels ;)

Great! Thanks. I’m doing this upgrade on my Vl this weekend.

Awesome! In case you want to do the wiring upgrade, I’ll be uploading a new video of me installing a Walbro 525 in my XR6 with heavy duty wiring. If I decide to upgrade the wiring on the VL (I’ll inspect for any melted or brittle wiring since the upgrade) I’ll do the same as what the video will show as it’s pretty straight forward. Thanks for watching!

Did you happen to send the Return to the Centre Crimped return on sender?

[@PangazShed]

I used the original location as the submersible hose in tank was still in one piece

[@SMRR35]

Have you run into any problems with replacing the two standard fuel pumps with the one Walbro 255? Does the wiring and relay need to be upgraded?

[@PangazShed]

No problems as the original has a lift pump in tank and a high pressure outside of tank. The 255 is higher in spec that it can handle the lifting and sending to the rail no worries. I didn’t upgrade the wiring as the 255 isn’t a power hungry pump. I would if I went for 460/525 which I recently done to my XR6. But the wiring upgrade was simple really.

Hi mate what turbo smart fuel reg did you use and has it been working ok for you?

[@PangazShed]

Hi there, I used the TS-0404-1015. And it’s been working good. Cheers

Can i just slap the walbro 255 in without upgrading fuel reg. Itd be more for reliability over the two pumps.

[@PangazShed]

You should be able to. I done a major pump upgrade on my XR6 without changing reg, but the factory reg on those are capable. I’m not sure if you would like to trust an old RB30 reg though. Cheers!

[@nickbest573]

I've ordered fuel reg. So I may re watch this. Thanks
