Post up your FI fuel systems
Like the title says. My fuel pressure drops at WOT from 60lbs to 45lbs and It's scarring the crap outta me so I want to see how to remedy this.
Mine:
60#morton Injectors
Walbro 255l intank pump
KB boost-a-pump
What else to i need? I am runnin about 13 to 14lbs of boost.
TIA
Mike

I hope I don't have the same problem. I am waiting for Racetronix's Rail Mounted Fuel Pressure Regulator.

Your regulator is most likely causing that drop. How is your AFR?

I never drop below 14 psi or much above that either.
Running 12 lbs of boost.
I would be afraid of getting a lean condition with loss of pressure. I would be careful with WOT until you remedy the fuel pressure situation.Last edited by cham; 08-08-2005 at 04:14 PM.

I was thinking about maybe putting in another fuel pump in the tank and a pressure regulator. I will check that out.

You might want to pull your pump out again and check the rubber fuel hose going to it. I had similar problems with my fuel pressure on my walbro 255 come to notice the hose was tearing in half and exploding. If you can get a hold of some real high pressure fuel hose swap it out. Some reason the hose they gave me with the kit lasted two weeks. Threw in a goodyear hose just to give me some time till I got some high pressure hose and that only last 2 weeks. At idle I would have 70psi at the rails but on the gas I would lose pressure.

I will tell you guys what I have in the making.
60 #'s Motron
2 255's walbro intanks
2 Aeroquip Socketless Hose Ends -6 AER-FBM1512
4 Aeroquip Socketless Hose Ends -8 AER-FBM1513
1 Earl's Performance Bulkhead Adapter Fittings EAR-983308ERL
1 Earl's Performance Bulkhead Nuts EAR-992408ERL
1 MagnaFlow Y Fittings MRF-MP-6286
1 Russell Aluminum Fuel Line Adapters (For the return from fuel rail.)
20 ft Summit Fuel Line Combination Kits -8 SUM-PUMPKIT3 (This might change if my stainless tubing comes in and I custom bend it to look like stock )
4 ft of Summit Fuel Line -6 (For the intank Y block setup. You dont want to go cheap here. The cheap ass hoses they send with the pumps wont hold.)
Speed INC fuel rails
Speed Inc fuel filter
Speed INC fuel pressure reg with boost reference
Hot wire fuel pump kit http://cgi.ebay.com/ebaymotors/1999-...spagenameZWDVW
Blocked off the T and removed the OEM fuel filter. This way you can use the old feed line as a return. This is not a cheap setup. This is all in all about $600 to $700. Not including the price of the injectors. But this would support 850 rwhp no prob. IMHO
And here is what inspired me to do this. http://www.cofba.org/users/smokinhawk/fuel.htmLast edited by JMBLOWNWS6; 08-13-2005 at 09:57 PM.

True but it is nice to have more than enough fuel pressure. Just a peace of mind thing.

Nice job hiding the coils and plug wires. I cant find any of them. Where did you stick the 8 coils in that packed engine bay and why cant I see your plug wires?
