I'd like to be sure I'm getting clean gas through the system. Would there be any problem installing a clear fuel filter before the fuel pump to check for debris?
I have mine installed after the fuel pump. I have to change it about every 5,000 miles because they get to where they don't want to let gas through for some reason, meaning when you floor it or climb a big hill, it will start to loose power and cut out. Mine never has much of anything in it, but I figgure it never hurts to have an extra filter there.
I don't think you would have a problem with it. Just keep an eye on it and be sure it doesn't become clogged. You should be fine.
Yes. I used clear line on my '74 Grabber because my uncle had it laying around and gave it to me. It was the kind that resistant to chemicals, acids and solvents. You can see it here in my gallery: It didn't melt or anything, but after several months it started to yellow (as you can see) and it got kind of hard. When I swapped the engine over to my '72, I just used standard black hose.
I use the a clear FRAM fuel filter between my fender apron and fuel pump ... works great ... I wouldn't mess with one of those cheapo glass ones ... Here is the one I use .... available any any Wal-Mart ... http://cgi.ebay.com/ebaymotors/FRAM-Fuel-Filter-G10MDP-fits-5-16-line-B1078_W0QQcmdZViewItemQQcategoryZ35597QQihZ006QQitemZ160011836020QQrdZ1QQsspagenameZWD1V
I agree, the glass filters are horrible. I tried using them and it seems like the fittings break too easily.
i was having problems with a flooding carb. the solution was two filters. one near the fuel tank made of metal 3/8" and a glass fuel filter after the mechanical fuel pump/ holley fuel pressure regulator one year ago and no more floodding. you have to keep a eye on the glass filter !! they come lose sometimes !!
i mounted one of the ...big rig...filters on my mav. it is plumbed between the fuel pump and the carb. it is about the size of a large screw on oil filter and filters water also. i can't find the pic. of it ..frank...
And you made fun of my air filter that filters oil . My opinion is that although you can install a gas filter before the pump, you should consider the pump is not really designed to suck too hard. If the filter before the pump begins to get dirty, you will notice driveability problems sooner than one getting dirty after the pump. If I were to install one before the pump, it would be a large clear one. You should have a sock on the end of your pick up tube, that should be all you need before the pump. This leads me to wonder, how about a magnet placed just inside the sender opening? Placed as low as possible though. Any body done that?
One benefit of having the filter before the pump is that there is no pressure ... just vacuum so there is not chance of it leaking.
Dan makes a good point. I have had problems with mine leaking in the past when I didn't have the clamp tightened down enough, and that's just not good. When I put my '69.5 together, I think I am going to put the filter before the pump. I'm going to re-route my steel line so that it comes out behind the shock tower instead of in front of it. Then I can hide the filter behind the shock tower.
It's recommended that you use a stainless steel or nylon mesh type filter before a fuel pump, whether it's mechanical or electric. Mesh filters have a lot less resistance to flow compared to paper filters so the pump doesn't need to suck as hard. Many electric pumps can't suck at all, that's why you have to mount them lower than the fuel supply to keep them primed.
keep the hood closed then you can hide the shock tower the filter is hiding behind ...all but Jamies friend frank... J/K
