Interesting set up. Ken- I really do appreciate you taking the time to help. I am beginning to understand it a little better. Now I just have to pay for it. I spoke with Summit tech today who conveyed some of the same concerns you expressed- i.e. not leaving fuel pressure gauges in place except for tuning.
Remember what I said in the beginning of my build thread... A build thread for dummies. So here is how I have decided to go:
1.Fuel tank…-6AN with 3/8” Teflon lined braided SS line goes to…
2. Summit Racing Inline Billet Fuel Filters SUM-230118R, Inline Mount, Billet Aluminum, red, 100 Microns, -8 AN Inlet/Outlet, Each SUM-230118r. This fuel filter allows for excellent flow. A 6/8 reducer will need to be on the filter as it is 8AN. It then goes to…
3. Walbro High-Pressure Inline Fuel Pumps GSL392, Electric, External, High Pressure, 255 lph,VPN-GSL392.
*I have been back and forth about having a fuel pressure gauge after the pump. My concern is if I spring a leak, I’m not digging the outcome. If I ran one, it would be…
4. Auto Gage, Fuel Pressure, 0-60 psi, 1 1/2 in., Analog, liquid filled, Mechanical, ATM-2176. It will work off of resistance, so if the engine is at idle, it will show actual pressure. When throttle is applied the psi will go down on the gauge as resistance is reduced. Then the next destination is to the factory supplied surge tank.
5.The surge tank should be mounted above the height of the final pump to the rails. This is important so that gravity can do its thing. The surge tank feeds to the Bosche fuel pump.
6. Bosch 044, Electric, 200 lph, External, Inline, Gasoline, Universal BCH-61944. After further investigation, it is actually 300 lph (even though it is listed on Summitt as 200 lph). From there it is off to another filter…
7. Fuel Filter, Inline Mount, Aluminum, Red, 40 Microns, -6 AN Male Inlet/Outlet, SUM-230100. Now on to the regulator…
8. Aeromotive A1000-6 Injected Bypass Regulators 13109 Fuel Pressure Regulator, 30-70 psi, Clear and Red Anodized, Universal, AEI-13109. I had considered the WIX all in one regulator/filter. While it saves $$ negating the expense of the extra filter etc., my concern is that it is not adjustable. Apparently, it regulates pressure to approximately 58 psi and flow rate cannot be changed. Additionally, I wanted a way to monitor pressure while in motion. Thus…
9. Auto Meter Ultra-Lite Analog Gauges 4371. This fits into the regulator port and carries an electrical signal to a gauge that is in the cockpit. My thinking is that now I can see fuel pressure while in motion, yet not have as much a concern for fire if analog gauges are left in place and they spring a leak. If an analog gauge was to be used here, it would be Autogage Analog Gauges 2177, Fuel Pressure, 0-100 psi, 1 1/2 in., Analog, liquid filled, Mechanical. Exiting the regulator, lines will go back to the surge tank or to the fuel rails.
10. Excess fuel is returned from the regulator back into the surge tank. The surge tank can then have overflow returned to the main tank.
11.The connection to the rail will not be with an AN fitting, but instead with Swagelok part number is #SS-600-6-6AN. Again, this reduces the chances of leakage under pressure…
12. The fuel rail will be reversed so it is on the driver’s side.
Also, I would like to give thanks to Fran for giving me direction. I feel like I have overcome a hurtle in my endeavor. I feel like I take a lot from people on the forum without being able to give much back. I hope my specifics on my planning and build can be helpful for someone else...
