mundawg Posted May 25, 2008 Report Share Posted May 25, 2008 Hi all, Was looking for some advice for a fule system for my 4age into ke70 and was just wondering what people think. Is a surge tank the way to go, or can i just get by with a vl inline send pump. Any help would be much appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
Sam_Q Posted May 25, 2008 Report Share Posted May 25, 2008 keep the fuel above a quarter and you should be fine just using the vl pump. A tip though when you buy the pump buy the whole bracket with the ruber mounts as those pumps arnt quiet Quote Link to comment Share on other sites More sharing options...

Sam_Q Posted May 25, 2008 Report Share Posted May 25, 2008 yes thats right, which has to be a low pressure pump... or you could run both pumps externally. Quote Link to comment Share on other sites More sharing options...
turbo_rolla Posted May 26, 2008 Report Share Posted May 26, 2008 i've run both external and intank setups and recently changed over to internal lifter pump and Vl pump under the car now. Was all in the boot before with an external VL lifter pump flowing into a surge tank, then going through VL high pressure pump to send it up the front. Did the job, but was noisy as f$#k in the boot :lolcry: i've now got a custom setup with a VL INTANK lifter pump mounted on the ke70 gear, running to VL pump mounted under the cap - HEAPS better, alot quieter (can hardly hear it in cabin), and wont get busted by the cops if they pop the boot to see all your fuel setup in there. Havent had any problems with fuel cutout yet, but if you keep it above a 1/4 like sam Q said you'll be fine :yes: Quote Link to comment Share on other sites More sharing options...
Taz_Rx Posted May 27, 2008 Report Share Posted May 27, 2008 yes thats right, which has to be a low pressure pump... or you could run both pumps externally. This is all good, provided you don't use an in-tank pump (as a lifter) that has a relief valve on the pump body. Its sort of like a regulator, but once it starts making edequate pressure, it will relieve itself by shirting fuel out of the body of the pump. Fine in-tank, external = boot full of fuel. :lolcry: Any carby pump (fuelpro, facet, carter, holley etc) will always make a good external lifter. Another thing to bare in my when selecting a lift pump is weather the pump is self priming, (can push well, but suck too) carters for example. Holley pumps are not self priming and need to be gravity fed by mounting it below tank level. So workout WHERE you want your setup, then select appropriate pumps. :yes: Quote Link to comment Share on other sites More sharing options...
Sam_Q Posted May 27, 2008 Report Share Posted May 27, 2008 sorry what do you mean by this: "external = boot full of fuel" good info too BTW Quote Link to comment Share on other sites More sharing options...

Sam_Q Posted May 27, 2008 Report Share Posted May 27, 2008 so your basicly saying that this would happen if the pump was mounted in the boot of a car and would relieve itself. I think its lunacy to put a fuel pump in the boot of my car personally... Especially how much room there is under corollas/sprinters Quote Link to comment Share on other sites More sharing options...
greenmac80 Posted May 28, 2008 Report Share Posted May 28, 2008 I'm thinki putting a single external vl bosck pump rigged up to the drain plug of my fuel tank. just trying to keep the cost down because external lift pumps are quite expensive! how easy is it to put an intank pump into a fuek tank that isn't made for it? good or bad? this is to power my silvertop.

D1doony Posted June 3, 2008 Report Share Posted June 3, 2008 the simple and most effective fuel system is just to run a VL pump I'm running a VL pump in mine, and it only surges when its right at the end when you kick it out round a corner. cost me something like $30 Quote Link to comment Share on other sites More sharing options...
