Sensor in Secondary Fuel Rail ???

ooooooooooooo sounds good

That does look rather nice!

Just to add, most sensors run 1/8th NPT thread

Good effort!! If you need someone to supply you with Goodridge, get in touch

Can you not run the sensor in the FPR - those things usually have spare positions for fitting fuel pressure gauges and what not ?

Just a thought to save you machining the rail or doing extra work.

that is a very good point and i can see no reason why he carnt??

I did consider it but for me to machine a block of aluminium isn\'t a big job. Probably just machine it out of 3/4in alloy bar !

When I got home tonight I tried to prime the system without the plenum on. Can\'t really see too well but the FPR went to 42psi on open to atmosphere. Had a feel round and all is feeling ok.

One question, Once you turn the ignition off should the fuel system hold its pressure. If it doesn\'t is that a sign of a leak ?? Trying to play it safe.

If I made this a kit there would be a few changes to try and improve the fitting of the kit. On a plus side it would be easy to make a 4x1600 kit with -8 lines off this design.

Plus on the FPR sensor side not too keen on if it will look a bit heath robinson when on the front of the plenum, the sensor looks quite naff, would rather have it mounted on the fire wall.

oops, plus the sensor looks like its an M12 thread. Need to get some m12 nuts to check though !

Top job mate, one Q is what size hose and AN fittings did you use,looking to do that on mine, Also where you bought it from.

shaunwil · February 16, 2009, 07:32:03 PM

Its all -6AN lines.

I was thinking about doing something similar to this, but I\'m keeping the 8mm lines.

Basically I was just going to hack apart the seconday rail, leaving the sensor bit in the middle and then welding (when I say I someone else would do this bit) the two end bits on.

The reason I was thinking of doing this is because even though I\'ve got a rotary art seconday fuel rail (which is fricken maaaahooosive), the standard fuel rail seems to have the sensor offset. I didn\'t want to tap the new fuel rail to add the sensor in the middle of the rail and mess up the flow.

Here\'s my version in case anyone is interested.

Just cut the ends off the old secondary rail and got some new fittings welded on by a company in Farnham.

Not tried it yet, but think it should work.

Was thinking of placing it in between the new secondary rail and the FPR

Cool, I\'m going to be buying some 1inx2in bar and machine a sensor block.

Ordered my material and Drills and Taps. Done a quick model of setup :

Will be a -6AN inline jobbie.
