Morningall, ,just going through my bits cupboard and came accross a fuel king pressure regulator ,I bought this during the build and never used it. Do many of you guys use or can enlighten the pros and cons of using or not using one? My set up is a rear mounted spun tank above the motor,stock mechanical fuel pump , in line glass filter feeding a copy mexican carb on 1600 twinport. All running pretty well no flat spots ,enough power, little rich on start up due to auto choke set up never  been quite right . Best left alone   ? Thanks in advance 👍

You tend to use a regulator with aftermarket carbs like the Webbers and Dellortos.  This is because these carbs do not run well with a feed above 2.5psi.  The stock mechanical and also electrical fuel pumps will put out more pressure than this.

I have a filter king regulator, separate filter. Use it to set pressure to feed my twin Kadrons.

Hi Buddy,

Sorry but I cant comment on the regulator but I saw that you've said there is a "glass in line filter", from past experience and comments from other users, if its one of those washable motorcycle/kit car filters be careful as they leak badly or break all of a sudden.
Your choice but just passing on some chat and info.

Cheers H

As Hunter say, be careful with the glass filters. Fire waiting to happen. I've a cartridge type in an aluminium housing. The filter is removable for washing or replacement 👍

the filter king with a glass bowl as one unit is fine the only suspect area on older ones will be the seal and ethanol suitability.

Snoopy, think Hunter means the glass cartridge in line type 🤷🏻‍♂️

The glass on the Filter King is probably thicker and stronger than the metal its attached to - near bulletproof 

understood that but some may not have seen one as the glass bowls were mainly on diesels the inline Chinese glass version is best avoided. any filter apart from the glass filter king type should be on the gravity fed part not the pressurised part of the system.

I have a filter king for my buggy.

You need to keep the filter high up out the way of stones but easily accessed. The glass is handy to visibly see if the filter needs swapped out. Not an issue with the aluminium cover but needs opened to check the filter. So a bit of a trade off.

Good because the set up is a quality unit. A bit of a step up from in line lawn mower filters.

thanks for that ; should i swap for a plastic chuck away one with the paper element inside ?

Better/safer than a inline glass one

These glass ones are dangerous




Wheras these plastic ones are significantly much safer






The Malpassi Filter Kings units with glass bowls are superb, however, you should NOT leave the fuel gauge attached, as that is dangerous.

Better/safer than a inline glass one 

noted 👍I have a new plastic one here
