Introducing the only simple and affordable plug and play fuel pump upgrade solution for the 350Z and G35. (Using an OEM fuel pump assembly.)
3 steps: Remove your stock fuel pump assembly, install the VQfuelupgrades.com upgraded assembly, and tune! (We also recommend upgrading to larger fuel injectors before tuning.)
No need to cut, drill, trim, file, or modify your stock fuel pump assembly. We do all the work for you!
Choose your fuel pump upgrade:
- Stage 1+ DeatschWerks 265lph (Model# 9-651-1000)
-
- Almost double the flow of the stock fuel pump! This will be the most common option that fits the needs of most VQ owners. Recommended for all naturally aspirated builds on either pump gas or E85! Will work with boosted VQ's but on pump gas only. We do not recommend Stage 1 for boosted with E85 fuel. Good for up to approximately 500whp.
- Stage 2+ DeatschWerks 345lph (Model# 9-307-1000)
-
- Works with boosted VQ's up to approximately 550whp.
STAGE 3 AND 3+ RECOMMENDED TO CONVERT YOUR FUEL SYSTEM TO RETURN-STYLE WITH A HARDWIRE RELAY KIT
- Stage 3 Walbro 450lph (Model# F90000274)
- One of the best pumps for the fully built and boosted! Tried and tested on countless builds, and known to be rock solid and reliable. Good for up to approximately 750whp. We also strongly recommend converting to a return fuel system at this point and adding a fuel pump hardwire kit for better power connection.
- Stage 3+ Walbro 525lph (Model# F90000285)
- New for 2018! Known as the "Hellcat" of in-tank fuel pumps! The highest flowing ultra high performance fuel pump in the market today! Good for up to 800+whp on a single in-tank pump which was unheard of... until now.
Core Option:
- I will send my stock core in to upgrade.
- Choosing this option means you will send us your stock fuel pump assembly and we will install your fuel pump upgrade into it.
- I will send in my core after. (Add $250 *refundable core charge)
- Choosing this option gives you the least amount of downtime for your car which is perfect for daily drivers! We send you an already upgraded core with the pump of your choice. Send us your stock core back and the $250 core charge is *refunded. *To be eligible for refund, the fuel pump assembly must be unmodified and undamaged. Please also refer to stock core return deadlines.
- I want to keep my core (Add $300)
- Choose this option if you would like to keep your stock core. We send you an already upgraded core with the upgraded pump of your choice and you will not need to send us back your stock fuel pump assembly. Keep your stock fuel pump assembly just in case you ever need to go back to stock!
- I want a brand new OEM Nissan fuel pump assembly (Add $355)
- Choose this option if you would like us to upgrade a brand new OEM Nissan fuel pump assembly. You will not need to send us back your stock fuel pump assembly.
VQfuelupgrades.com fuel pump assembly features and process:
- We start with your Nissan/Infiniti stock core fuel pump assembly that you sent into us, or a core from our current inventory. (Cores are OEM assemblies pulled from working vehicles. The assembly will show signs of normal wear and tear.) We can also start with a brand new OEM fuel pump assembly as well.
- The stock 150lph fuel pump is removed and replaced with your upgraded fuel pump of choice. Pump bracket and pump itself are both physically modified to ensure proper fitment. Then the upgraded pump is secured into place.
- Swirl jet is modified to support the higher flowing pump.
- Stock fuel pressure regulator is also modified to relieve extra fuel pressure buildup. This prevents abnormally high fuel pressures. (*This step is skipped if converting to a return fuel system, which requires an external adjustable fuel pressure regulator and return correction).
Return Correction Option:
*Please note when adding the return correction option, there are other parts (not included) that are needed to complete the return fuel system conversion. OEM fuel pump assembly with the return correction option installed will NOT work with the stock returnless fuel system. However, the fuel pump assembly can always be re-modified in the future when converting to return.
Hardwire kit:
Adding a hardwire kit is recommended when choosing Stage 3 or Stage 3+ due to the extra current/amps drawn by the Walbro 450/525.
STOCK CORE RETURN DEADLINES:
- Core returns must be shipped by the following deadlines in order to receive refund on your core deposit:
- If your core is shipped within 15 days you will receive the full $250 refund.
- If your core is shipped within 16-30 days you will receive a $150 refund.
- If your core is shipped within 31+ days you will receive a $50 refund.
Compatibility:
2003-2009 Nissan 350Z
