Fuel pressure spring...

[jp0863]

Rebuilding the tbi on my burb. When I pulled it apart, the fuel pressure spring was broken. Where can I get a new one? Also what about replacing it with a higher pressure spring, any benefits?

13 psi seems the hot ticket.

get new or good used spring and adjustable parts here and gauge setup to dial it in. http://www.rvmorsemachine.com/newproducts.htm

some have reported the stock pump wont flow good volume at the 18psi mark unless you put in a bigger pump.

TBI's love the higher pressure.. I run 13.5 on my BB....

Mr Injector has the springs and other parts you may need when getting injectors serviced.

Stock motor and chip handles 13 to 14 nicely, making sure your throttle blades have a minimum air setting really helps idle when you have increased pressure. As the TBI wears the throttle blades close making it harder for fuel above throttle blades to mix with air.

15 PSI IIRC is max a stock pump will handle at WOT. It may do more at idle but drop when volume is maxed...
