TexasEd 188 Report post Posted August 14, 2020 I saw a post a while back about the proper fuel filter location. I think it said it was supposed to be between the tank and the pump. Mine is between the pump and the carb. Where is is supposed to go and what type is the correct appearance? I have a 69 with 302. Thanks Quote Share this post Link to post Share on other sites
Redstang69 2 Report post Posted August 14, 2020 I could be wrong but the original carbs were Autolites and they had the filter built into them. I'm far from a pro though, so don't take my word for gospel. 2 Caseyrhe and 69RavenConv reacted to this Quote Share this post Link to post Share on other sites
69RavenConv 286 Report post Posted August 15, 2020 I want to say the OEM filter was located at the input to the carburetor. It was a metal (brass?) fitting with a screen-type filter element inside. Maybe an inch or two long that threaded between the hard fuel line and the carb body - badically part of the carb like Redstang said (welcome to the site!). But it's been years since I looked my original 2100 and my memory is getting old. I inserted an aftermarket filter between the pump and my Holley carb years ago. 1 Caseyrhe reacted to this Quote Share this post Link to post Share on other sites
LoneWolf2U 136 Report post Posted August 15, 2020 Stock was inline pump and carb. 2vs were screwed directly into carb. Using a stock puller pump place filter before carb. Using a pusher pump place it between tank and pump. good rule of thumb. 1 69RavenConv reacted to this Quote Share this post Link to post Share on other sites
rmarks 20 Report post Posted August 15, 2020 The 1969 Autolite 4300 carb had the fuel filter screwed into the carb itself. See pic: 1 69RavenConv reacted to this Quote Share this post Link to post Share on other sites
Brian Conway 264 Report post Posted August 15, 2020 FWIW; After my purchase of the M6905 Carter fuel pump I needed to change the filter location on my Holley 3310-1 carb.. Moved on to the Holley filters that fit into the fuel bowl inlet. Quote Share this post Link to post Share on other sites
TexasEd 188 Report post Posted August 15, 2020 Great. My Autolite carb is damaged and in a box. It is replaced with a Holley and I have the filter in between carb and pump (Carter mechanical pump). I'm using a filter that I don't like the look so next change I'll put a smaller diameter one on. Quote Share this post Link to post Share on other sites

JayEstes 172 Report post Posted August 16, 2020 I have a 69 302 coupe - I believe I’m still running original equipment on the carb. It has the 4100 carb with fuel filter screwed into it coming straight out of the front. Small section of rubber hose connects the steel fuel line.

Does that heat up the choke if the car is hot but has been sitting? 1 JayEstes reacted to this Quote Share this post Link to post Share on other sites

Always has for me; there is a water valve to turn off (reduce) flow through the heater core when it is off. 1 JayEstes reacted to this Quote Share this post Link to post Share on other sites

Terry, my factory AC cars have water valve on heater hose, non-AC cars do not and coolant always circulate through heater core. 2 Mach1 Driver and JayEstes reacted to this Quote Share this post Link to post Share on other sites
JayEstes 172 Report post Posted August 18, 2020 Heater line past choke seems to work fine for me but I may be missing the gist of your question.. if the car is already warm, the choke setting doesn’t matter as much as when cold. Best thing about that choke is it doesn’t require electricity - even less stuff to worry about. And as Aslanefe says, there is a vacuum valve on AC cars to cease water flow thru this hose if controls inside set right (mine does have the original Tecumseh AC compressor on there - Rebuilt, but not hooked up right now however) Quote Share this post Link to post Share on other sites
69RavenConv 286 Report post Posted August 18, 2020 I always assumed Ford routed the heater hose this way to better gauge/utilize engine temperature at the choke. Imagine driving 55 mph down the road in Minneapolis in January and how long it would take to open a non-electric choke without the hose. Quote Share this post Link to post Share on other sites
TexasEd 188 Report post Posted August 18, 2020 Thanks for the explanations. I have a factory non-AC car with Dealer AC and installed on a 302. It originally had the manifold heat riser but that rusted away in the 80s and has had a Holley with electric choke since then. I sometimes have issues starting my car when the engine is warm after sitting a while. The choke closes while sitting and the car wants it open. Maybe it's an adjustment issue but it is fine after 60 seconds of running. It would be cool to remove the electric line and use the heater hose to open the choke. Having the non AC car with dealer AC makes it interesting for me. I'm getting ready to tear down to the heater box and restore everything and put in an R134 conversion AC system that uses the dealer AC routing. Quote Share this post Link to post Share on other sites
