filter king close call

[stagmuffin]

i had a issue with my malpassi 85mm filter king the other day and it came about when i decided to change filters . i have been running the paper element type filter and decided to change to the fine stainless mesh type morso for convenience as it can be flushed and refitted . well i removed the old cleaned the glass bowl and fitted the new st/st one upon tightening the knurled bowl nut i started the car and shortly later it leaked so i took the whole unit off as it is difficult to see the seal when fitted, i assembled off the car and refitted all seemed fine anyway went for a run today and when i came back i could smell petrol fumes i opened the bonnet to find fuel peeing down onto my exhaust manifold quickly shut it all down and luckily no harm but close i had missed a hairline fracture in the glass bowl which expanded when warm and could of caused a fire killing my stag .ive removed the unit and refitted the old type filter with new fuel hose while i track down an aluminium replacement bowl instead of glass its know wonder they are not allowed the glass in motor sport . im going to rethink the whole position of the fuel supply under bonnet to try and keep it as far away from the exhausts as possible . so if you have one of these fitted please check them and your fuel pipes .

Hi StagMuffin, I have a Filter King fitted but it is fitted in the boot directly ahead of the pump tucked up on top of the wheel arch. It has always had an aluminium bowl as it was transferred from my Spitfire after I finished racing.

hi Ian ,any pictures i may move mine as im not happy with it up front in all the heat anyway and if it were that far away it would be safer less prone to fires i would hope .is yours 67mm or 85mm im trying to find the ally bowl but not in stock anywhere at present for the 85mm which i have. so ive got a temp set up with the old type filter,i did notice my engine seemed to be somewhat less responsive after reverting it is slightly hesitant at times but ive no way of governing fuel pressure delivery to my holly without the F/k

Hi Steve, I'll try with the photos today. Because the space restriction I had to remove the pressure gauge off the top of the unit but I have refitted it on a bracket mounted on the firewall. I am running an Eidelbrock 500 4 barrel and very pleased with it. I guess by 67or 85 you mean the diameter of the bowl, I'll measure mine.

Hi Steve, I cant find how to load the pictures I took. The method in the forum heading doesn't work. I'll try to describe it. My unit is 65mm. I can't remember if I used the original mounting bracket or fabricated one but I pop riveted it to diagonal brace that runs inside the back guard, very fiddly. It is spaced equidistant between the pump and the inner wheel arch and tucked in so the carpet trim board just covers it. I cut the outlet pipe from the pump and with suitable hose replumbed it through the filter. If I can work out how to send the pictures I will. Hope this makes sense and helps.
Cheers Ian

Ian that's great and a good idea ,its miles away from any heat and im guessing there is ample room to perform a filter change and also if a leak occured it is not as iminenlty dangerous as on in the bay over hot exhaust manifolds !! i will look at it this week end .
thanks

thanks Ian that looks like a nice neat solution ,i think i will be following your lead . what would we do without the youngsters lol, have you fitted a pre as well as post pump filter ?i know the plastic one is a flame trap for the vent just curious about the pre cant decide whether or not it is worth doing while im there.

Hi Steve, No prefilter, didn't actually consider one.
