While going through my fuel system I'm installing a new 1/2 inch sender in the tank without a fuel sock. So, I want to install a pre-filter in the line before the fuel pump which is a stock stage 1 pump. To start with I'm retaining the factory 3/8 fuel lines in the frame. It's been suggested (by Larry the Wizard) that I install the billet fuel filter in place of the rubber section underneath the driver's door but, it may not fit in place of the rubber section. (The billet filter I'm using is about 5 inches long including the hose barbs) So, I'm asking if anyone has tapped a filter in back by the gas tank or, maybe up on the frame next to the fuel pump? If so, pics would be nice.
That would do it. I've got the RobbMC short billet filter coming in along with the 1/2 in. sender so, I'll see if it will fit under the driver's door. If not, I'll either use it or the WIX in back near the tank. Thanks, guys.
1 is supply line from pump 2 is from regulator to filter 3 is filter to 3/8 stainless to EFI 4 is regulator bypass back to tank. (high bypass to facilitate deadhead to EFI) I run this exact setup for both my 1964 Skylark with 2x4 EFI on nailhead and single EFI on my 1968 Skylark 430.
Or...dont know what genius first said "I think we should cut this pressurized line with flared fittings at both ends right in between carburetor and fuel pump overtop the exhaust then let's only use two teeny tiny little hose clamps" no no no keep that fire extinguisher away from me I will never need one
Well, perhaps your sarcasm refers to my post where I cut 5 inches out of the fuel line to install a tap for a fuel pressure gauge. I suggest that your concern is less than valid and here's why..................First of all that section doesn't even come close to going "overtop of the exhaust". It's actually further away from my stock exhaust manifold than the two rubber fuel lines that go into the fuel pump from the factory. In addition those two stock fuel lines are in "direct line of sight" to the manifold whereas the fuel line I cut that runs next to the timing cover is not even in sight of the manifold. As for the hardware I used, the rubber line is a high quality emission/fuel hose and the two hose barbs are secured with fuel injection quality clamps. (Not tiny little hose clamps). Also, the pressurized fuel line will never see pressure past about 8 psi. So I suggest that, although you certainly have the right to your opinion, your concern is without merit.
Me, too. How far does fuel spray when pressurized to 8 psi? And then the hot fuel vapor is blown around by the rad fan. He's completely correct. The rubber hoses at the pump have essentially no pressure in them--one is actually a suction hose. Air leaks in, fuel doesn't spray out. The other is a vapor return, restricted by an orifice in the pump, and simply draining back to the tank. Hose on the pressure side of the fuel pump needs to be considered very carefully, eliminated if possible, otherwise minimized and inspected regularly.
I use one of RobbMc's billet fuel filters under the driver's door on my 350 GS, it was recommended along with their 1/2" pick-up, fuel line and their pump for the 350
Allow me to reittreate Im not sure who th FIRST GENIUS WAS.... However any following ones are redily recognize I believe you have this as well in hand as I do my ABC extinguisher & ask th sensative types to stand back & hold your skirt down & parinoid type should be reashured that its not all about you day & wish to thank all for illuminatin th fire hazzard & lack of extinguishers in perportion to premium....topic...
