Default Fuel Pump to Carb Plumbing

Getting ready to install fuel pump, which is a 110gph Edelbrock pump. I would like to get ideas on how to plumb the fuel line up to the carb. My set-up does not have a return line. I would like to install some sort of inline fuel filter somewhere like midway between the pump and the inlet of the fuel line to the carb. Possibly mount the filter to the front of the passenger side head or something? I did a search and came up with a few photos from Lars and a few other guys, but would like to see how others have routed their fuel lines/filters from the pump to the carb. Any photos that any of you can provide would be appreciated. Thanks!

This was a vendor supplied L-88 fuel line. Notice the cr**py fit. I cut that line and installed a fuel filter just n front of the right head. Since this was taken, I think it's on Rev5 of the fuel line. The latest one fits perfectly, lays right along the rocker cover with plenty of room to get the cover off and is all straight. All -6AN hardware and a high flow T fitting.

Can't see in this picture, but there's a short radius 90* bend at the fuel pump, the line runs straight up to the filter with a -6AN flare, the rest you can see.

Depends on the carb but you might be able to find a hardline with filter integrated as you can see in the picture. bought SS tube, a cheap tube cutter and a cheap bender. Added swadgelok AN couplings and after a day had a line from the pump going up and the 90 degree bend to the filter. (I prefered one piece but there was no way I could get it in).

I made this one from tubing and fittings from my local parts store. I used a stock replacement line from the pump and modified to fit the filter. It's a stock fuel pump.





I added a bracket for the filter later. It's a coil bracket from a Ford. It fits the ACDelco GF652 filter perfect and lines up with a bolt hole in the head.

I like those adapters on the filter and really like that bracket. I followed Lars' instructions and bent my own, and use that same filter. Will try to scrounge up some pictures.

The adapters are made by a company called Weatherhead. You can order them from Napa. The part# is WH 1446.

I did this one following Lars build paper. I like the bracket idea and will have to look into getting one.

Send Lars an e-mail and ask him for a copy of his paper on bending fuel lines, it will tell you pretty much everything you need to know.

....and being made of steel, transfers heat from the cylinder head into the fuel just before it enters the carburettor. Is this what you really want?

I'm not trying to be a smart-****, but I cannot see any benefit from adding that bracket. If GM chose not to add a bracket in that area, perhaps that is a good guide to all of us not to do so either. All I can see happening is that the fuel will enter the carburettor hotter than it should be, and this could lead to hot starting issues on a warm day.

Regards from Down Under.

The 63 - 65 used a filter bracket as did the 68 - 69 with the GF432 filter. No issues to date.

I am not a big fan of the stock style set up. I went electric and ran an fuel line. I came off the fender well and into the back of the carb to eliminate heat.


this set up could still be done on a stock engine and carb. you just mount the regulator and filter on the firewall or in the fender well.

There are reasons why fuel lines, filters and especially fuel pumps were all mounted at or hear the front of the engine and somewhat in line with the radiator fan airflow. Coolest part of the engine compartment. This is especially true for the mech fuel pump where vapor pressure can be critical.

Your biggest hurdle is going to be getting AN fittings to clear the crossmember. When I had my edelbrock mechanical pump I had to cut the 90 degree inlet fitting since it had more threads than the pump would take then I used a 45 degree hose fitting to the rubber line connected to the factory metal line on the frame, by doing this I gained enough clearance to get the pump in place. The rest was easier but the outlet line pointed at the harmonic balancer but with different angles I cleared it and went up past the lower radiator house.

I used a Mallory 3140 filter on the fender well then a fuel pressure regulator bolted to the cylinder head then a duel line to my Holley carb. The lines weren't custom made due to the cost but I bought the shortest available at my local speed shop to get things working at the time. I have since moved things around with the installation of Vintage Air and it looks better than in this photo. This was the only pic I could find and it has to be 2 years old but hope it might help some. Good Luck

Hey guys, thanks for all of the photos and suggestions. I kind of have in my mind how I want plum the lines/route hoses, etc. Unfortunately, there are no local engine shops around my area to buy any of the fittings and hoses, so I will have to place an order online. Might be a week or two to get everything ordered that I will need. In the meantime, if any of you have some close-ups of how your hoses are run from the factory fuel line on the frame to the inlet of the pump, that would be helpful. Thanks!
