For those interested, I replaced the stock in tank(low pressure), with a 86 fiero tpi pump on the cosworth, should have the same pickup/sending unit as the other vegas,as the tank it self is different on cosworths not the pickups or in tank pump. I had to cut the end off that holds the sock(and the pump) and extend it about 2.5 inches because the fiero pump is longer, its easy and would work great on any tpi motor. simple cheap and do it yourself, I am also pretty sure other intank gm pumps are the same as well,, P.S. the fiero pump is only $15 on ebay, sure beats a $130 walbro, or equivalent, with some research you could do the same mod for a TBI system as well(using a gm TBI pump they have a pressure of 18psi , A very wise elderly friend of mine taught me to spend time thinking, before spending money with my wallet. I came up with this fix because of the high cost of a replacement secondary(high pressure) pump on a cosworth,,,TImmy

If you don't have time/money to do it right the first time,how will you have time/money to do it again. Timmy
