GrayZee Posted March 3, 2004 Share Posted March 3, 2004 I had a idea to replace the old rusty fuel tank with a custom made new tank, but with a high performance option. I thought why not make it with a flange on top of the tank to accomodate a in tank fuel pump? I asked some questions at the local parts store for a suitable pump. I wanted a pump with these features.. readily available anywhere cheap! able to feed a high HP engine I came up with a pump from a mid 90's chevy pickup fuel pump, and as a added bonus I found out that those pumps have a built in fuel level sending unit. I did plan on getting one of those autometer fuel level gauges (the ones with the ford ohm rating) to match the rest of my gauges. The ohm rating is close to the nissan sending unit but it isn't the same. So if I were to use this chevy pump idea, I would just buy the autometer gauge designed for chevys (perfect match!) This tank is still in the pre-design stage but I have a buddy that has the ability to make some dies and press out new tanks. Problem is that unless there are several people interested it wouldn't be worth his time to fabricate the dies. I've got a extra tank that I'm gonna show him this weekend. We'll have a look at designing a new tank, but in the meantime I'd like to get some input from you guys what you think of this idea and if anybody would be interested? Also if anyone has some views on a more suitable fuel pump I'm open to ideas. I have no idea what the gallon/min rating of the chevy pump is(anyone know?) but I'm sure it'll feed a modestly hybrid'ed Zcar. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted March 3, 2004 Share Posted March 3, 2004 Walbro GL392... chevy fuel pump won't keep up with a high output turbo engine I am sure. The walbro is just an inline pump, but it can be had as a drop in as well. (maybe a toyota supra spec'd walbro would be good) The walbro's are becoming quite common and easy to find. They are also much less expensive than most of the competition. Quote Link to comment Share on other sites More sharing options...
GrayZee Posted March 6, 2004 Author Share Posted March 6, 2004 You say a fuel pump designed for use with a Chevy V8 isn't enough to feed a turbo'd L28? What if it was a pump for a Chevy SS 454 V8? Quote Link to comment Share on other sites More sharing options...
Drax240z Posted March 6, 2004 Share Posted March 6, 2004 The problem isn't flow at 40psi, the problem is what does that chevy pump flow if it has to put out the 40psi base fuel pressure, + 25psi boost pressure? I am willing to bet that a standard 454 chevy pump will do diddly at 65psi output pressure... certainly not supplying the volume that a boosted engine needs when under boost. I might be wrong, the 454 pump might put out enough fuel at 65 psi to still support 400hp, but I personally doubt it. Hence the popularity of the Walbro pumps... they'll pump a lot of fuel at higher pressures. Quote Link to comment Share on other sites More sharing options...
