in line fuel filter ok ?
 

47 ford truck

anybody use an inline fuel filter between the tank and stock fuel pump?
will it screw with the fuel pressure too much?
are there any "old school" ways to check fuel pressure after the pump?

thanks for any input , trying to chase a ghost and not very carb smart

Re: in line fuel filter ok ?
 

i always use an inline filter between tank and pump and between pump and carb and haven't had any pressure issues to speak of. i also use a pressure gauge and regulator and i don't recall any old school ways to check the pressure without a gauge. it is fun to look for the coolest gauge and they are out there. i recently picked up a real old airplane gauge/regulator but i seem to have misplaced it for now so can't post a pic.

This is just my theory, but I think the mechanical pumps are better at pushing than pulling, so a filter between the pump and carburetor is better. Consistent with this idea, I once installed a filter between the tank and pump in my 51 tudor (near the pump inlet), and it starved for fuel climbing a hill on a hot day. I removed the filter (~5 years ago) and it hasn't happened since, for what its worth (knock on wood)!. Good luck, Ken

I'm running a 500 cfm four-barrel on my 276, and I'm feeding it primarily with a stock mechanical pump; I have an electric pump back by the tank for priming and emergencies.

I have an inline filter between the tank and the electric pump, and another one between the mechanical pump and the carburetor.

My mechanical pump puts out an honest 3.5 gph, and the four-barrel has never been starved for fuel.

starting to sound like the in line filter is not my problem

starts and idles fine, once it warms up and you get 5 miles down the road it dies, will not start back up until it sits awhile

not even close to overheating, new electronic ignition (set at 19 on the vacc guage),plenty of fuel in the filter and bowl, the carb was rebuilt by someone? unknown

thanks
back to the drawing board

if you have a filter in between the tank and fuel pump i dont think you need one inbetween the carb and pump.

Maniac,
Your problem is your coil, not fuel. Next time it stalls and won't restart, pull a plug wire and hold it next to a stud nut while cranking with ignition on. Odds are that you'll find a weak orange spark. Should be 1'2" long, very bright blue.

Once the coil gets warm, it fails and won't produce a strong spark until cool again.

Remove the coil and send it to Skip Haney for rebuild.

i have a filter between the tank and the pump, i drive my 36 all the time and have no trouble with the fuel system at all

I have one between the pump and carb and a glass bowl pump w/ceramic stone in the glass bowl.Never had troubles with 2 filters. Stock 36.i know wrong pump but works for me. ken ct.

the coil was on my hit list, but i thought it should be okay since its new
any way to check the coil before it dies 5 miles from home?

New like as in nos script one,most are no good even though {new} Have it rebuilt,can only be done if script. Send to skip haney in Fl. and get a napa # IH-200 condenser. ken ct.

Another thought - is your gas tank cap properly vented? I had a 52 tudor awhile back that ran great for a few miles, then would die. I pulled my hair out trying to troubleshoot the problem, then thought about the tank. Sure enough when the problem occurred and the car died I opened the cap and released the vacuum that had formed in the gas tank. Turns out someone in the past had replaced the stock gas cap with a non-vented cap. Quick work on the cap with an 1/8" drill bit fixed the problem.

Sounds like the coil as others have said. If it runs rough before it dies, it could also be crud in the gas tank.

If the truck is new to you, and having problem out on the road.
I have a 52 f1 and did it, on my new ride.Drain the tank,clean and blow out gas line make sure it not blocked.I have put filters before and after fuel pumps.Most of the time on old cars its gas problem.These mini filter they may look clean but can be pluged.
