I need rid of the rubber fuel line between the fuel pump and carb on my SBC. What I want to run is 3/8" steel brakeline with flare fittings at each end (with male adapters at the carb & pump) and include a small in-line filter that has flare fittings already on the ends (female flare). Does anybody know of a small filter that might fill the bill? Everything I see advertised is now either hose barbs or AN stuff. I really don't like either. I did a mock-up with some AN fittings but they looked to m***ive to me. I like the OEM SBC set-up with the small filter spliced in using rubber hose ******s and clamps...............just thought it would look cleaner with the flare fittings. Below is a picture of an AC Delco GF652 which might be the right size, but may have AN fittings. If it's the right size, with flare fittings it'll look great chromed.
So, how do you plan to avoid the vibrations that can harden your brakeline/fuel line and cause it to crack? Chevy mad that line out of rubber for a reason, methinks.
I'm running hard line from tank to pump except for a short piece of rubber between the framerail and pump to keep that from happening. It shouldn't be a problem between the pump and carb, should it?
That filter was designed to be mounted on the frame rail, and because of that, it's size isn't something that will fit or look "right" between the pump and the carb.
I have this one on mu Chop. The fittings are 1/8" female NPT fittings. it might work for you. THey are not pricy at all and you can get replacement filters / gl*** for it.
The AC filter you show uses o-ring fittings to seal, tuff to find. Voh shows the kind I would use if you can get it with a larger threaded hole, 1/8 pipe has a really small inside diameter. peace
Run the hard line to a filter on the frame and from there to the hose at the fuel pump. Pep Boys usually have them on a peg board. Get a universal in line fuel filter that comes with connector hoses. Make a bulge in the hard line by making the first step of a double flare. The short pieces of hose get replaced every time the filter gets replaced and never live long enough to fail. The one in your picture looks like a modern fuel injection filter that must withstand high pressures. (no hoses) It'll work but overkill $$ for me. There are still millions of cars with neoprene hose connectors. It's really not a problem to lose sleep over. IMHO. If you want to run a fuel filter up on the engine then get something old and cool looking....
I'm running an inline filter near tank in the hardline to the fuel pump. I could be wrong, but nothing can get in the line, so why run filter near carb? I do have a sintered filter at inlet of carb from factory.
I'm not a fan of the type that have the gl*** cylinder trapped at either end by a chrome cap. I've seen too many of them accidently get broken... Then what do you do?? HOWEVER! I've always liked the sediment bowl filters, when I can find a good quality one. Unfortunately there is someone out there making an AC gl*** bowl filter with a paper filter and the filter they provide for it is completely JUNK. Got it from a corvette resto place on-line somewhere. The paper element actually DROPPED OFF in the bowl on TWO of them. JUNK! SO! Does anyone have a good source for the sediment bowl filters that are of good quality?
You can still find those gl*** bowl filters at implement places. Maybe not as pretty as the ones pictured.
Every stock carburetored rig I have seen with a mechanical pump runs a hard line from the fuel pump to the carb if it hasn't been altered or modified. I'm like Kendeuce in that I put an inline filter between the tank and the fuel pump on everything I build or set up. That should keep any dirt out of the fuel pump. I don't and never did care for those sediment bowl filter setups as they often do leak especially if you change the filters on a regular basis. Fram a**** others makes an inline filter that bolts to the frame rail and has a replaceable cartridge. I have a couple of filters off 75 Cad Sevilles that were mounted near the tank and have a spin off cover and use the same element that most Cad engines used for years. Good flow, easy to service and not spendy.
My 800 Ford tractor uses a sediment bowl like that-hasn't had a filter insert-if there was one- for 30 years-but it's a tractor motor so it seems to like dirt.
I don't use anything but a hard line from the fuel pump to the carb. I generally run one of those red Holley inline filters (takes the old Ford fuel pump element) before the fuel pump. I get nervous with plastic, gl*** and fuel on top of a hot engine. Just my 2¢. Bob
I am running dual Carter/Weber carbs on my inline 292. I am using 5/16 steel line between the pump and the carbs with a filter in between.I think it was for 1983 ford ****** and it looks like your photo. One end is inverted flare which worked great the other was 1/8 NPT but with the NPT to IF adapter it worked fine.
Most SBC if stock had hard line from pump to carb. I read somewhere once that GM policy did not allow anything but steel on the pressure side of the pump, in the days of engine driven pumps. Mopar inserted a small filter with rubber connectors, but supplied new rubber and clamps with each filter. 2nd on the Seville filter...I think it will have some sort of flare fittings. If not, look for aftermarket with pipe threads and get receptacle fittings for the flare.
