If your line vapor lock is happening after a WOT, its getting heat soak from a header/exhaust pipe. Shield or wrap the fuel line prior to the pump. If you use the corvette vented fuel filter and your return line, it can't vapor lock up there (past pump) as the (boiling fuel) pressure is going to...

I personally have thought about EFI a ton. But living out west it doesn’t get too cold and my carb has worked great. Takes some work to start in the freezing but 2600$ to me is too much.

Okay cool, yeah I do have that fuel sender with that extra outlet, hopefully this helps my hot starts after shut off.

Man it's just hard to justify the price at this point. Would be nice not having to crank the engine over and over due to percolation and just knowing that it's going to fire up on first crank and be close to dialed in all the time but the cost is huge. Blueprint engines said they'd honor the...

Failure : I purchased a premade braided fuel line from Jegs to use as a return line from the fuel pump to the fuel cell as I had installed a new cell. The fittings leaked, I kept checking to see if they were tight and they were. I went to my local speed and had a new hose made and he told me...

I’ve said it twice here and multiple times on the forum in other places. We can preach it till we’re blue in the face, but people are going to do what they want to do. I wish I could hit the agree button multiple times on your post.

If nothing else, sump the tank. The vent MUST be the same diameter or bigger than pump feed line. Some will say it doesn’t matter but it does. Especially with a return line. Get rid of the filter before the pump. If your tank isn’t full of **** there is zero reason to have a filter before the...

Yes. https://www.oreillyauto.com/detail/c/wix/fuel-delivery/carburetors---parts/fuel-filter-water-separator/6bf814fc80d2/wix-fuel-filter/wix0/33054/v/a/1770/automotive-truck-1984-dodge-d150-pickup-rwd?q=fuel+filter&pos=1

I really feel like this is a sort of vapor lock situation. The return line from the engine compartment back to the tank is not hooked up and the regulator I have is not set up for a return line. I have ordered a regulator with a return and will try that first. If I wind up going with an electric...

All of the Pep Boys auto parts stores around here, did a huge clearance and closed up. A couple of months later, they reopened as Autozones. The Pep Boys tire and auto centers stayed open through all of that. One of their techs told me that Autozone bought up Pep Boys and all of them would do...

Good memories! Thanks for the story on the fuel issue. I have been considering running a return line and this has sold me on the extra work to do it. Thank you.

You can do a return line with that type of regulator but it’s not that great. You can buy a really nice return regulator that doesn’t creep for about 160 bucks. That’s cheap money.

I had the same problem with my bracket car on ethanol based gas, I now only run non ethanol fuel & I've had a return line since the car was built.

It worked out great for me. I’ll probably do all future swaps like that too. When I eventually go to put a 360 in the ole dart with my V8 904 trans I’ll definitely do it like that. Just have to rebuild that 360 first. Definitely needs a set of new lifters. I think that was the issue it had. I...

@TT5.9mag Yes, Agree. I will be running return from the regulator. Magna fuel makes the provision to run return from the pump housing to the tank, but I can see from Rat's explanation how that would be similar to deadheading. Im gonna go from Cell to pump with 10. From Pump to regulator with...

no worries mate , youuu can doooo it !

It is not large enough AND THAT LINE IS THE FUEL TANK VENT You can buy aftermarket senders that hae a second port, but it "is known" that aftermarket senders suck for gauge accuracy. If you pull the filler tube you could modify it for a vent and or weld a port in it for the...

Fired the Colt today before big rain headed our way. It's funny, I ran the fuel pump many times yesterday with no leak issues. I come out this morning and the gargae smells like a gas refinery. The fuel filter top bolt is leaking and 2 of the banjos on the carbs are leaking. The oil filled...

I think you're *** backward. 1/2" feed line and 3/8" return line. I was using 1/4" return with 1/2 " feed.

You can use any size return you want with most pumps. There is at least one Barry Grant pump I know of that uses the return line to control fuel pressure. Too small a return line and the fuel pressure is too high. Too big and you won’t have any fuel pressure. Other than that, the return line...

Yes. This is the one I am using.

yes, the mallory 4309 Mallory Ignition 4309 Mallory Fuel Pressure Regulators | Summit Racing im not sure if you can compare a return style regulator with a return filter, because they generally are intended to be used with different pumps according to the instructions, if the return line is...

That's just not true as a blanket statement. It totally depends on what pump you have, how many GPH it flows and at what PSI. Some manual pumps (which he's running) don't have enough flow to over come the loss from a large return, thereby starving the carburetor from sending too much back to the...

Thanks @Mattax you have a great attention to detail! That’s and extra boot that is in the middle of the spark plug wire. I plan to cut it off because it looks tacky but, both ends of that wire are snapped snug to distributor and spark plug. Also, you’re the first to mention the exhaust. We...

I had a 70s kneeknocker in there. Between that and the york compressor from the same time, it was just dead weight. Eventually I'll swap over to a unit that replaces the factory heater box and does it all. Modern compressors are lighter, and the heater box replacements are the same weight or...

From what little I know mid 70’s to mid 80’ Gran fury and Diplomats. If you find one make sure you get the fuel pump and bolts. The top of the pump is narrower to clear the plumbing of the oil return line. Also take all of the oil lines and fittings to the block and fuel pump. The bracket can be...

It has a stock tank with 3/8 fuel line and, 1/4 return line, a Carter CRT6903 mechanical pump from the pump it has all -6 an steel braided lines to the Holley HLY-12-803 regulator then, -6 an steel braided line through an Earls filter to a Holley 850 double pumper. I really feel the regulator is...

This may be what I end up doing. I can remove the stock line and use it for a pattern for the 3/8 supply and 1/4 return I plan to add.

LOL well that puts a whole different light................and I likely won't be much help. One big issue with "build your own" is that you can create a siphon situation if you are not careful.

Hello all. I am looking for a return-style fuel pressure regulator. I am running a pair of 1964 Carter 3705 AFB carbs on a Stage II Ramcharger cross ram. I have a 1/2" line from my pumps up to the front of the car. What size return line should I run, and what regulator do you all recommend? I...
