I read on a site last night that a weber 45 DCOE like 3psi 3.5 tops.The stock pump on my 83 puts out 4.5 psi.Anyone know who makes a resonable priced FPR?



Thanks

Thats what my first thought was too.But if I start it and leave the pump fuse in it floods out but if I turn the pump on for a second and then off repeatedly I can keep it running for awhile.Just annoying.I have new plugs in it too to help the motor start.RE-A plugs at that.$75 for 4 plugs.

Yea I run a weber 48 Ida downdraft, anything over four psi and mine acts like a snowblower pop,pop,vroooooom,pop,pop.. I use the big port holley fpr with the intake scaled down to 3.5 psi with one port to the carb and one port to a fuel pressure guage inside the car... I am going to buy a new fuel pump (have the holley blue pump) because it is so loud... but other than that runs nice...

my sidedraft ran liek crap if i had like 10 PSI per the holley POS gauge...anything between 4 and 7 and it was ok. flames were also much fun...

lets see, i dropped a whole second one day at the track by upping the fuel PSI and launching at a higher rpm...



i have a weber/dell performance manual. let me know if u need anything looked up.

I have one you can have for like $5,



But I think you would be better off finding one that varies with engine load. Especially since you are running a DCOE. The bowls are too small to keep the engine fed at high RPM. If the pressure is too high at idle the needle won't seat and it will flood. If its too low it will starve, lean and bang!! Then you will need an engine and a VFPR.

What make is it?Do you think it will work for up to 7500rpm shifts?It for my daily driver 83.My Turbo is EFI.
