Picked up 5 mpg and cured 90% of my Weber woes with a Holley fuel pressure regulator. Part # 12 804. It's even preset at 3 lb. At least mine was.

I have a spare one in the garage if anyone wants it. I have Dellortos, and the pressure regulator came with some spare parts I bought. Just cover the postage and its yours.

Cheers,

ducinthebay, PM sent!!

How did you know which Holley fuel pressure regulator to buy? Where did you purchase yours? Was installation difficult? I recently purchased a 1987 Paso but don't know much about the Weber and the associated problems you mention. Thanks, Horse

Went to my local auto parts and went through catalog.Good parts guy was a big help! Installation was easy as there is alot of room under all that bodywork. Made a bracket and mounted it to the motormount bolts on right side.

I contacted Holley and they did tell me that a bracket would have to be modified for it to work on the Paso. Can you provide any details on your bracket design and how it has worked for you. That would be greatly appreciated. Thanks!

didn't modify the stock bracket at all. just made a bracket to mount the holley bracket to and mounted that to a motor mount bolt.

Sounds good. Next time you have the fairings off can you PM me a photo? I would really appreciate seeing one.

sorry! pretty much computer dummy. Lucky to be doing this! Just cut a rectangular piece of 1/8 steel wide enough to span the two motor mount bolts in the v and long enough to hold the regulator. Make sure it doesn't rub on anything, bolt it up and enjoy! Not a cure all, but worth the trouble.

Hi, thank you for this important info, I'm thinking to do the same.
I still have some problems with weber carb around 5,000 RPM ...before and after 5,000 is just fine.
Do you think will resolve this problem?
I never use one of those, how do you connect it?
Thanks a lot, salvatore

Thanks mickster, I used your info, went ahead and bought one of these on E-bay last week and installed it today. Initial try looks good, easy to start now and best of all not stalling anymore! I did not really see a need to mount the regulator in my case, maybe the fuel lines have already been modified, I don't know,but the regulator weighs almost nothing and fits quite nicely under the tank, I just used a cable tie, and all seems well.The regulator has one inlet and two outlets, one to the carb, and the other goes back to the suction side of the pump as a bypass. All good,thanks for sharing, you helped me out.Cheers.
