Q. Is the Hobbs pressure switch included with the DP system?
A. A 15 PSI Hobbs pressure switch and interface harness are included with the system as standard equipment. 15PSI is the best pressure at which to activate the secondary fuel pump in most Turbo Buicks. Ideally, the secondary pump should be activated approximately 100HP shy of the primary pump running out of fuel to prevent pressure spikes or lean conditions. Some customers have computers that can control both pumps via the jumpers (shown in our picture) on our dual harness. Some customers have upgraded return lines and choose to run both pumps all the time. We recommend using either your computer or our Hobbs switch to control the secondary pump. This reduces the electrical load, fuel heating, and wear on the secondary pump. The primary and secondary pump may be easily switched by swapping the control jumpers if you wish to balance out the run-time on the pumps. The DP harness comes with both control jumpers plugged in as shown in our ad. In addition to this the DP harness comes with a Weather-Pack connector so you can interface the secondary pump control to your aftermarket computer or any pull-to-ground signal.

Q. Can other pumps be used in the DP sender as an option?
A. This hanger can accommodate any 38mm body pump such as a 255, 340, 450 or 525LPH pump in single or dual configuration. CUrrently we are only offering this system with 2 x Walbro F90000274 or 2 x F90000285 pumps. NOTE: WE DO NOT ACCEPT CUSTOMER-SUPPLIED PUMPS TO BE INCORPORATED INTO OUR DP SYSTEM PERIOD!

Q. Is this DP system E85 compatible?
A. The DFPS-G71050 DP hanger uses Walbro F90000285 (Hellcat) pumps which are 100% Ethanol compatible. True E85 factory certified systems have their electrical connections fully isolated from the fuel which is impossible given the Turbo Buick’s tank design. Modern E85 Flex-Fuel systems are manufactured with special plastics and metals. Fuel system health will impact pump life.

Q. Can I buy the entire DP system in a D-I-Y format?
A. We DO NOT offer this item as a D-I-Y kit.

Q. I already have some other pumps. Can I use them with your system?
A. NOTE: DUE TO PROBLEMS WITH CUSTOMER-SUPPLIED PUMPS AND PRODUCTION FLOW ISSUES WE DO NOT ACCEPT CUSTOMER-SUPPLIED PUMPS TO BE INCORPORATED INTO OUR DP SYSTEM NOR DO WE OFFER IT LESS PUMPS. ALL DP SYSTEMS ARE SOLD AS COMPLETE TESTED SYSTEMS.

Q. I have a digital dash car. Do you have a 120-ohm level sensor for me?
A. Yes, please specify the digital dash level sender option when ordering your system.

Q. What size of fuel lines do you recommend with this system?
A. We recommend conductive PTFE (Teflon) braided -8 feed and a -6 return lines minimum. We do not recommend any type of rubber (braided or not) for use with modern-day fuels. These PTFE (Teflon) lines will be able to support over 90% of the full performance of this DP systems. For maximum performance, we recommend a -10 feed line. Please view our G7 PnP fuel line kits by clicking > HERE <

Q. Where is the biggest restriction in the fuel system?
A. The factory steel lines running up the front of the motor.

Q. Can I use a volt-booster with your system?
A. Yes, we recommend a voltage booster for increased system voltage which benefits pump performance under WOT only.

Q. What brand of fuel pressure regulator do you recommend?
A. Racetronix REG-G7B1 (factory location / best option) or Racetronix REG-FI886BS universal with aftermarket fuel rail configurations.

Q. Where do I get support and installation information?
A. All technical and warranty support is now provided by your Racetronix dealer ONLY!

Q. What are the performance specs of the DP system?
A. These are the typical test bench specs with 2 x F90000285 Walbro 525 Hellcat pumps using stodart solvent @ 20°C:
• 948 LPH @ 43.5psi @ 14.0v @ 37.3A
• 1038 LPH @ 43.5psi @ 16.0v @ 40.8A
• 798 LPH @ 80.0psi @ 14.0v @ 42.7A
• 918 LPH @ 80.0psi @ 16.0v @ 48.0A

Q. How much HP will this system support in a Turbo Buick? (Will it support my HP requirements?)

A. Multiply your HP by 0.42 which will give you the required fuel in LPH with a 20% safety margin. You must consider the flow at your maximum boost pressure. For example, if your base fuel pressure is 43.5PSI and your regulator increases 1LB of fuel pressure for every 1 LB of boost and you run 20 PSI of boost your maximum fuel pressure would be 63.5PSI. Using the flow data above, confirm that the DP system is able to provide the required flow at your maximum fuel pressure and voltage. This calculation does not factor restrictions in the fuel lines. Since the condition of each system tends to vary it is best to run a return flow test at max fuel pressure once the DP is installed to determine if upgrading the fuel lines is required. Note that some Racetronix customers have run mid-8-second 1/4 mile times at 160 MPH+ using our 680 LPH dual system, deluxe Teflon line kit on race gas.

Q. Are there higher flowing pumps that I can substitute in this system?
A. Currently the F90000285 Walbro 525 (Hellcat) pumps are the highest flowing available at this time.
