Fuel system for Weber IDA 48 need help

priobe · #1 (**permalink**) 03-12-2007, 09:20 AM

Hello All,

I would like to find out what most of you are using for a fuel system on the IDA 48's. I am currently using the banjo setup and experiencing leaks after awhile, I am guessing from the vibration of the motor even with new gaskets. I was thinking of using AN "T" fittings to get away from the banjo setup. Has anyone used this option? If so what is the size and thread pitch of the Weber Body.

Also, I am currently using a Holley "Blue" fuel pump for this setup. I am not happy with this pump because I am noticing a change in PSI from 3-0 psi and a nasty noise. I have read some post as to the Blue pump leaving people stranded.

I am currently looking into the Mallory 110 GPH or the Aeromotive P/N 11209 90 GPH. Does anyone have any suggestions with these pumps or a different one.

hello Priobe; my recomendations are edelbrock electric fuel pump, made by essex, part # 1791. also holley low pressure regulator adjusted to no more than 3 lbs pressure. in my opinion this pump is a two thumbs up.

Thanks for the reply on the post. Its seems kind of wierd the way the fuel enters the pump and leaves. I am not sure if this pump will work for me. I will look into it.
It also seems like most of the time when I post something pertaining to Weber carbs there are alot of views but nobody responds.

Thank you for your respond

Priobe,

I use the low pressure Holley regulator as well. Do you have a fuel pressure gauge after the regulator, a good investment IMHO. I use 2 VDO gauges from www.bugsandbuggies.com part number 153-002. Non-liquid filled, 1 1/2" dia.
I have mine set to 3psi.

i have gone through 2 of the blue holley pumps and both ceased up over a short period of time.

Yes, I have a fuel PSI set to 3 psi when the motor is cold and then I readjust it to 3 psi when it falls to 0 psi when the Holley blue warms up. I guess this is an added feature which I did not pay for.

Thats why I am looking to go with another pump.

yes, i have fuel pressure guage in line after the regulator as well.

priobe,
in order to get rid of the leaks at the banjos throw the weber gaskets away and get 2 sets each of EARLS STAT-O-SEAL 1/2 and 9/16. With that you are done.
If you insist in AN fittings, JAYCEE makes an adapter for the Webers to AN. Check their web page.
If you have trouble with the electric fuel pump, dump it, get the mechanical one back in, get a Holley fuel regulator (they have one for a max of 4.5 psi) and install a return line from the second regulator output to somewhere before your fuel pump with a restrictor inside( 1 -2mm hole) to drain the pressure away when stopping the engine. It works.

Thanks for the info. I will return my an fitting and save myself alot of money. I could take that money now and buy jets to tune these carbs.

I thought that the regulator from Holley was called a dead head regulator which did not use a return line. I ended up getting an Essex Regulator that made the return line possible.

Eljaro ,are you talking about the washers on either side of the aluminum fuel block that the banjo bolt goes through, one small on the inside and a larger one on the outside of the block? mine leak like crazy.

exactly those two damn leaking gaskets at both sides of the banjo or fuel block can be replaced by the Stat-o-Seal gaskets. These are very similar to seals used in hidraulics, basically a metalic washer with an o-ring embeded in the inside. Works wonders!

Summit carries them, I will order today. chuck

I use a Ford Racing mechanical pump and Aeromotive fuel pressure gauge and a Holley fuel pump regulator on my 289 SB. Canned the Holley electric pump a couple of years ago.

The car runs quite well with the mechanical pump.

I too an looking for the correct washers, but my fuel block is the one pictured. I like the small design of the Dowty seals, but not sure of what size. I also need the correct banjo bolts for this block. Any suggestions?
